token_riskPre-trade safety score for any Base token — Pass a token contract address and get a risk score + flags (ERC-20 conformance, ownership renounce, upgradeable proxy) computed live from Base. Built for trading bots and agents that vet tokens before buying. Required input: address. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
pre_trade_gateOne call before you trade — GO / HOLD / STOP — The single call an agent makes before touching a Base token: token risk + sellability (honeypot/tax) + route/price-impact + deployer reputation, collapsed into one GO/HOLD/STOP verdict with an auditable receipt. Cheaper than the four checks à la carte. This is the tool to bind first. Required input: address. Priced $0.10 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
sign_guardShould the agent sign THIS calldata? GO/HOLD/STOP — The check before the riskiest moment — signing. Decodes raw unsigned calldata (approve / permit / transfer / setApprovalForAll), shows the exact intent (who gets power over what, and whether it's UNLIMITED), and screens the destination + spender for OFAC sanctions and dangerous owner powers, in one GO/HOLD/STOP verdict + receipt. No simulation needed — pure decode + onchain risk. Catches the unlimited-approval drain vector before it's signed. Required input: data. Priced $0.06 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
spend_auditWhich apps/agents can pull funds from this Base wallet? — Base Account spend permissions let an app or agent spend a scoped, recurring allowance from a wallet — the primitive behind autonomous agent payments on Base. This reconstructs a wallet's ACTIVE spend permissions from onchain approve/revoke events and flags the dangerous ones: unlimited allowance, no expiry, unrecognized spender. The Base-native, agent-era drain check that ERC-20 approval tools can't see. Required input: wallet. Priced $0.05 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
agent_wallet_auditEvery way this wallet can be drained without a fresh signature — The complete fund-movement authority on a Base wallet in one call: ERC-20 approvals (a spender you approved can pull the token) PLUS Base Account spend permissions (the agent-era scoped recurring allowance) — one drain-surface verdict with the ERC-20 revoke queue to act on. Approval tools miss the spend permissions; spend-permission tools miss the approvals. The only combined check for agent wallets that must know their whole exposure before holding funds. Required input: wallet. Priced $0.06 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
wallet_delegationIs this EOA secretly running someone else's code? — Since Pectra an EOA can carry EIP-7702 delegated code (the 0xef0100 designator): every call to the wallet executes the DELEGATE's contract with the wallet's funds — a malicious delegate is total takeover, invisible to approval tools. Reads the designator, resolves the delegate and verdicts it: not_delegated / delegated_known (Coinbase's EOA→SmartWallet path) / delegated_unknown (🚨) / smart_contract. The drain surface no other Base tool checks. Required input: wallet. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
commerce_escrowAuth/capture payment reconciliation on Base — First tooling for Base's Commerce Payments protocol (AuthCaptureEscrow): reconciles two-phase auth/capture payments — in escrow, captured, charged, voided, refunded, or payer-RECLAIMABLE because the operator missed the capture window. Filter by payment= (infoHash), payer=, receiver= or operator=, or omit everything for the network feed. The order-reconciliation read merchants and agents need before trusting onchain commerce. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
commerce_operator_auditShould you trust this Commerce Payments operator? — Commerce Payments flows are DRIVEN by an operator — it authorizes escrow, captures for merchants and takes the fees. This audits one before you rely on it: 90-day volumes, fees taken, capture-vs-reclaim record (missed capture windows = merchants left unpaid), distinct payers and merchants. verdict: healthy_operator / mixed / sloppy_operator / no_activity. No other tool reads this new Base commerce protocol. Required input: operator. Priced $0.05 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
morpho_healthIs this Morpho lending position about to be liquidated? — First lending tooling in the catalog. Reads a Morpho Blue position on Base (the largest lending venue on Base) and returns its liquidation health in one call: health factor, current vs liquidation LTV, and the exact collateral price drop that triggers liquidation. Built for borrowing agents and treasuries that need to know how close they are before the market cuts them — Morpho's own API is deferred. Pass wallet= and optionally market= (defaults to cbBTC/USDC). Not financial advice. Required input: wallet. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
morpho_vaultShould you deposit into this MetaMorpho vault? — A MetaMorpho vault spreads your deposit across Morpho Blue markets — your real risk is WHERE the curator put it and WHO can move it. Reads the vault's live allocation (concentration, per-market collateral + liquidation LTV), idle share, performance fee, timelock, and control (curator/owner/guardian, and whether one address holds both). Returns a diversified / concentrated / control_risk verdict: the read before parking funds in a yield vault. vault= required. Not financial advice. Required input: vault. Priced $0.05 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
morpho_liquidatableWhich Base Morpho positions are liquidatable right now? — Built for liquidator / MEV searchers. Reconstructs the active borrower set on a Morpho Blue market from Borrow events, prices every position onchain in one multicall, and ranks them by liquidation health — flagging positions liquidatable NOW (health <= 1.0) and those one small move away, with the collateral price drop that tips each over. market= optional (defaults cbBTC/USDC), maxHealth= cutoff (default 1.1). Not financial advice. Priced $0.06 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
gas_payerWho pays this wallet's gas? Is it a sponsored smart account? — A smart account's gas can be paid by a PAYMASTER instead of the account itself — invisible to every 'does this wallet spend ETH' heuristic. Reads a wallet's UserOperationEvents across BOTH EntryPoints (v0.6 + v0.7): is it a smart account, its op count and success rate, and WHO sponsors its gas (self vs which paymaster, per-sponsor share). A fully-sponsored account is typically app- or agent-operated. wallet= required, days= optional (default 30, max 90). Not financial advice. Required input: wallet. Priced $0.05 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
paymaster_checkShould you trust this Base gas paymaster? — Given a paymaster address, audits whether it's a healthy, active gas sponsor. Reads its UserOperationEvents across both EntryPoints: sponsored op volume, distinct accounts served, success rate, total gas sponsored, and concentration (the share coming from its single busiest app). The read to run before integrating a paymaster (Coinbase / Pimlico / Alchemy / custom), or judging who funds a counterparty's gas. paymaster= required, days= optional (default 30, max 90). Not financial advice. Required input: paymaster. Priced $0.05 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
safe_checkReal M-of-N multisig, or a 1-of-1 that just looks like one? — Multisig / treasury intelligence. Given an address: is it a Gnosis Safe, its owners and M-of-N threshold, version, activity, and — critically — its enabled MODULES. A module can move the Safe's funds via execTransactionFromModule with no owner signatures, so each one is an address with unilateral control. Returns a multisig / single_signer / has_modules verdict: the counterparty check before you trust funds to a multisig. address= required. Not financial advice. Required input: address. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
first_funderWhere did this wallet's money originally come from? — Funding provenance in one call. Traces a Base wallet back to its EARLIEST transaction and resolves who first funded it: a recognized exchange/bridge (real on-ramp, lower risk), an anon EOA (possible sybil/burner — trace the cluster), or a contract. Returns the first funder, whether it's a contract or EOA, the initial value, and wallet age. The sybil/origin screen no other Base tool gives — the counterparty check before you transact. wallet= required. Not financial advice. Required input: wallet. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
fresh_bridgeIs this wallet's USDC freshly bridged, and from where? — Cross-chain inflow detection. Reads a wallet's recent USDC MINTS and correlates them with Circle CCTP receives to tell you whether its USDC is freshly bridged in (and from which source chain — Ethereum, Arbitrum, OP, Polygon, Solana…) vs natively issued. Freshly bridged capital is new money / a possible cross-chain hop — a real signal for trading and liquidation agents that no other Base tool surfaces. wallet= required, days= optional (default 30, max 90). Not financial advice. Required input: wallet. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
safe_to_sendIs this address safe to send, approve or sign to? — Before your agent sends, approves or signs to an address: one GO/REVIEW/STOP verdict. Screens OFAC sanctions, Coinbase/Basename identity, wallet vs contract, how long the address has existed, and whether contract logic can be swapped AFTER you send. Every factor returns what it found and what it could not read — a check that did not run never reads as clean, so GO means everything material was actually screened. Not financial advice. Required input: address. Priced $0.01 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
address_trustIs this counterparty Coinbase-verified or an anon/sybil? — The 'who am I dealing with?' check for agents. Reads Coinbase's ONCHAIN verification (an EAS attestation by verifications.coinbase.eth) — meaning the address is tied to a KYC'd Coinbase account, the strongest sybil-resistance signal on Base — plus the address's Basename. Returns a verified/named/anonymous verdict + trust score. Pair with sign-guard/spend-audit for a full pre-transaction gate. Identity is a signal, not proof of honesty. Required input: address. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
basename_profileFull onchain identity behind a Basename or address — Resolves the complete Base identity behind an address or Basename: resolved address, avatar, description, website and social handles (X/Twitter, GitHub, Farcaster, Discord) read from Base's L2 Resolver text records. Lets an agent turn a counterparty address into a real profile — beyond just the name. Complements address-trust (verification) with the human context. Required input: name. Priced $0.02 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
whale_flowIs size moving to the exits right now? — Flow, not snapshot: the largest transfers of a Base token in the last 24h, classified by whether whales are sending INTO DEX pools (sell pressure) or pulling OUT (accumulation) — a net sell-pressure read that decays in hours. Complements holder-forensics ('who could dump') with 'is anyone dumping now'. CDP-indexed events. Required input: address. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
watchlist_diffWhat changed on my tokens since last check? — Retention in one call: pass up to 10 tokens to snapshot them and get a watchId; call again with that watchId to get only the DELTAS since last time — liquidity ±%, price ±%, became-honeypot, sell-tax spiked, liquidity pulled. The second call is worth more than the first. Built for agents holding positions that re-check daily. Priced $0.06 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
address_intelInstant profile of any Base address — EOA vs contract, ETH + USDC balance, transaction count and activity level — straight from Base RPC. Useful for counterparty and wallet checks. Required input: address. Priced $0.02 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
gas_oracleLive Base gas estimates — slow / normal / fast — Returns current Base gas fees (baseFee, maxPriorityFee) and three tiered suggestions (slow, normal, fast) in Gwei, derived live from the Base RPC. Built for agents that time or cost-estimate transactions. Priced $0.01 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_safetyCan this Base-native (B20) token freeze or seize your funds? — Live — B20 is Base's native precompile token standard, and unlike ERC-20 a B20 issuer can freeze holders (Policy Registry) and even SEIZE your balance (burnBlocked) at the protocol level. This reads those powers — seizable, freezable, paused, rebase, uncapped-mint — into one hold/caution/avoid verdict, and separates a real tokenized stock from one merely wearing an equity ticker by reading the transfer-policy admin on chain, not a list: all 13 Coinbase equities, and the next on day one. Required input: address. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_gateOne GO/HOLD/STOP before you touch a B20 token — The single call before trading a Base-native B20: seize (burnBlocked) + freeze (Policy Registry) + rebase + pause + uncapped-mint, collapsed into one GO/HOLD/STOP verdict with an auditable receipt. Pass wallet= to also check if YOUR address is already blocked on that token. The B20 tool to bind first. Required input: address. Priced $0.10 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_transfer_preflightWill THIS transfer (from→to) clear right now? — The per-transaction B20 rail check: pass token + from + to (+ optional executor) and get one GO/HOLD/STOP on whether this exact transfer clears NOW — sender policy resolved against the sender, receiver policy against the recipient, executor policy against the operator, plus live transfer-pause. Every other B20 tool is per-token due diligence bought once; this is the check an agent runs on every payment. No ERC-20 tool can see it. Required inputs: address, from, to. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_portfolioWhich B20s in your wallet can freeze or seize you? — Scans a wallet's B20 (Base-native) holdings for protocol-level freeze/seize powers and whether YOUR address is ALREADY blocked on any of them — the risk no ERC-20 portfolio tool can see. Returns per-token seizable/freezable/rebase flags plus a wallet-level verdict. Built for agents holding Base positions. Required input: wallet. Priced $0.06 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_controlWHO can mint, seize, freeze or pause this B20? — b20-safety tells you WHICH powers a B20 has; this tells you WHO holds them. Reads the token's role-based access control (mint / burn / seize-via-burnBlocked / pause / admin) from onchain role events and reports the exact controllers, how centralized they are, and whether admin has been renounced. The issuer-control map an agent needs before holding a regulated Base-native asset. Required input: address. Priced $0.05 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_seizure_historyHas this issuer ever actually SEIZED holders? — Every other B20 check reads what the issuer CAN do; this reads what they HAVE done. Scans the token's actual burnBlocked seizures (the BurnedBlocked event) — whether the issuer has ever burned a blocked holder's balance, who was seized, and how much. verdict: enforced (has seized) / armed (can, hasn't) / no_seize_power. Pass wallet= for one address, or omit address= for the network-wide feed. Priced $0.05 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_authenticityIs this a REAL B20 — or a lookalike contract? — Run FIRST on any 'B20'. A scammer can deploy a normal contract at a vanity 0xB200… address and fake the whole B20 read surface — the B20Factory precompile is the one authority that can't be spoofed. Verifies factory registration + bytecode absence (real B20s are chain-native precompiles with no code). verdict: genuine / fake_lookalike / not_b20. The 2-cent check that keeps every other B20 answer honest. Required input: address. Priced $0.02 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_config_auditBricked scopes, dangling policies, frozen lists — The B20 misconfiguration lint. Base's docs warn: a scope bound to a NON-EXISTENT allowlist silently denies EVERYONE — transfers brick. Audits every policy scope for dangling bindings, ALWAYS_BLOCK, renounced (frozen) lists and live pauses; verdict bricked / critical_misconfig / misconfigured / clean plus a can-this-token-even-move flag. Pre-launch lint for issuers, stuck-funds guard for holders and merchants. Required input: address. Priced $0.05 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_policy_membersThe FULL blocklist/allowlist — every address, with history — b20-freeze-check answers one wallet; this enumerates the WHOLE list. Replays the Policy Registry's BlocklistUpdated/AllowlistUpdated events into the full membership of a B20's blocklist/allowlist: every address ever blocked or whitelisted, when, by whom, and the current member set per scope. Compliance-grade visibility no other tool provides. Pass address= (token) or policy= (registry policy ID). Priced $0.05 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_genesis_auditWhat the issuer did in the initCalls bypass window — createB20's initCalls run with role AND transfer-policy gates BYPASSED — a one-tx privilege window only the issuer ever gets. Reconstructs what they did in it: pre-mints (how much, to whom), role grants, policy bindings, blocklist seeding — the token's true starting conditions. verdict: blocklist_seeded / premined / configured_launch / bare_launch. Required input: address. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_mint_watchWho is printing this token, right now — b20-supply shows the dilution ceiling; this shows the actual printing. Every mint (incl. batchMint) in the window: amount, recipients, and the share of current supply it represents — heavy_dilution / active_minting / minor_minting / quiet. The live issuance feed for agents holding B20 stablecoins and RWAs. Pass days= (1-90, default 30). Required input: address. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_rebase_historyEvery silent balance rescaling this token ever did — An Asset B20's multiplier rescales EVERY holder's balance in one call — no transfer, no per-account event, nothing in your tx history. b20-rebase shows today's value; this replays the full MultiplierUpdated history and flags DOWNWARD moves that silently cut every holder. The operator's rebase track record, before you hold a rebasing RWA. Required input: address. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_pegDeclared currency vs what the market actually pays — A B20 Stablecoin's currency() is SELF-DECLARED — the standard verifies nothing. This is the missing check: declared peg vs actual DEX market price. 'Says USD, trades at $0.71' in one call: on_peg / depeg_warning / depegged / no_market (the peg is a pure claim with zero price discovery) / unverifiable_fx for non-USD pegs. Run before settling in any B20 stablecoin. Required input: address. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_dossierInstitutional AI report on a Base-native B20 token — The premium tier of the B20 suite — no ERC-20 tool can produce it. Composes the full B20 picture: seize/freeze/pause/mint powers, WHO holds them (admin renounced?), allowlist-vs-blocklist access model, supply-cap dilution headroom, metadata mutability, and ACTUAL seizure history (burnBlocked) — then Claude writes an institutional due-diligence verdict: issuer-control score, seizure risk (enforced/armed/none), red flags, and a hold/avoid recommendation. Required input: address. Priced $0.75 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_memoPayment IDs & compliance tags on a B20 token — B20 adds memos to transfers/mints/burns (transferWithMemo) for payment IDs, compliance tags and settlement correlation — a field ERC-20 has no equivalent for. Reads a token's on-chain Memo event history, optionally filtered by a specific memo (bytes32) or the caller wallet. The settlement-reconciliation primitive for agents paying over B20 stablecoins. Required input: address. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_supplyMint headroom & dilution history of a B20 — The dilution half of B20 rug risk (b20-safety covers seizure). Reads supply cap vs minted supply (how much can still be minted) plus the on-chain SupplyCapUpdated history — an issuer that RAISED the cap diluted, or set up to dilute, holders. Uncapped mint is flagged as the worst case. Pair with b20-control to see who holds the mint role. Required input: address. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_metadataCan this token rename itself? Has it? — A B20 with a METADATA_ROLE holder can call updateName/updateSymbol — change its own identity after launch (an impersonation / bait-and-switch vector ERC-20 has no protocol equivalent for). Reads whether the metadata is mutable (role holder exists) AND whether it has ALREADY been renamed on-chain (NameUpdated/SymbolUpdated history). Trust the address, not the label. Required input: address. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_permitGasless-approval (ERC-2612) readiness for agents — Every B20 has ERC-2612 permit built in — approve a spender by signature instead of a transaction. Reads exactly what an agent needs to build a valid permit: the token's DOMAIN_SEPARATOR, the owner's current nonce (so the signed payload can't be rejected/replayed), and the EIP-712 domain/type struct. Read-only — signs nothing. Required input: address. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_policy_adminWHO administers the blocklist that can freeze you? — b20-control reads the token's own roles; the address that can actually add you to a blocklist lives in the Policy Registry. This reads WHO administers each active transfer/mint policy (policyAdmin), and whether that control is being handed over (pendingPolicyAdmin) or renounced. The other half of 'who can freeze/seize you', straight from the registry. Required input: address. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_access_typePermissioned (allowlist) or blockable? Decoded per scope — A B20 transfer policy is either a BLOCKLIST (allowed unless listed) or an ALLOWLIST (allowed ONLY if listed — a permissioned/whitelist token you can't even receive uninvited). b20-safety flags that a policy exists; this decodes its TYPE per scope (send/receive/execute/mint) — the difference between 'the issuer can block bad actors' and 'this is a permissioned RWA you can't hold uninvited'. Required input: address. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_announcementsOn-chain issuer notices & corporate actions — B20 Asset tokens can post on-chain announcements (Announcement: id, description, uri) — issuer notices, corporate actions, redemptions — a channel ERC-20 has no equivalent for. Reads a token's announcement feed (active vs ended) from CDP-indexed events. The issuer-communications primitive for agents holding tokenized/RWA B20 assets. Required input: address. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_stablecoinDeclared peg currency + issuance & control — B20 Stablecoin tokens self-declare a fiat currency code (currency() → USD, EUR, …). Reads that declared peg alongside the issuance profile (supply, cap) and control powers (seize/freeze/pause/uncapped-mint) — a one-call 'what is this stablecoin and who controls it' for agents settling in B20 stablecoins. The currency code is the issuer's claim, not attested backing. Required input: address. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
base_withdrawalWhen can a Base→L1 withdrawal be finalized? — Beryl (2026-06-25) cut the single-proof withdrawal window from 7 days to 5, with a dual-proof fast path at ~1 day. Given a Base withdrawal-initiation tx, this decodes the L2ToL1MessagePasser event (the withdrawalHash, target & value needed to prove/finalize on L1) and estimates the finalization windows under the post-Beryl rules. For agents managing cross-chain liquidity. Required input: tx. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_launch_radarFreshly minted B20 tokens on Base — Lists the newest B20 tokens created on Base (from the B20Factory precompile) — variant, symbol, decimals, block. B20 is Base's native token standard and dozens launch hourly. A discovery feed for agents hunting new B20 launches early. Run b20-safety on any address before touching it — new ≠ safe.

b20_policy_watchDid this token BECOME seizable after launch? — The B20-only rug vector: a token can launch clean and later attach a sender blocklist (PolicyUpdated) — silently becoming seizable via burnBlocked. This reads the token's full policy/pause event timeline (CDP-indexed onchain events) plus the live policy state, and tells you if — and exactly WHEN — it turned seizable. Required input: address.

b20_guardReal-time alerts the moment a B20 token turns seizable — The live layer over B20 Policy Watch: a network-wide onchain webhook captures every B20 PolicyUpdated/Paused sub-second. Pass a token address for its live guard status, or call with no address for the feed of tokens that JUST attached a sender blocklist (turned seizable) across all of Base.

b20_freeze_checkIs YOUR wallet blocked or seizable on this B20 token? — Checks whether a specific wallet is authorized under a B20 token's transfer-sender policy. If it isn't, that wallet can't transfer and can be burnBlocked() (SEIZED) by the issuer. The personal companion to b20-safety — 'can this token freeze MY funds?' Required inputs: token, wallet.

stock_positionHow many shares does this wallet actually control? — B20 Asset tokens do NOT apply multiplier() to balanceOf() — measured on chain: a multiplier moved 1.0→2.0 while holder balances read identically. Coinbase settles splits and dividend adjustments on its 13 tokenized equities through that multiplier, so reading balanceOf as a share count is wrong by exactly that factor the day one fires. Returns both numbers per holding: what an unadjusted integrator shows, and what is owed. Wallet balances only; LP/lending is declared excluded, never zeroed. Required input: wallet. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.
b20_rebaseAsset-variant rebase multiplier & scaling risk — Reads a B20 Asset token's rebase multiplier — the factor that scales every holder's balance.

exit_liquidityCan you actually get OUT of this position? — Give a Base token + a trade size in USD → estimated buy AND sell price impact, whether you can unwind that size without collapsing the pool, and the largest safe exit.

sellabilityCan you actually SELL it — or is it a honeypot? — The hard honeypot question, answered three ways: security simulation (honeypot, cannot-sell-all, sell/buy tax, transfer-pausable), a LIVE transfer simulation we run ourselves from a real holder (reverts/taxed?), and exit liquidity.

holder_forensicsBenign vs dangerous concentration — who can dump — Goes past 'top-10 = X%' to classify the holder base: how much the creator & owner still hold, which top holders are infrastructure (LP/CEX/bridge — benign) vs unlabelled wallets (the concentration that can actually dump the price), and the largest non-infra wallet. Separating benign from dangerous concentration is the analysis others skip. Required input: address.
