Список инструментов сервера (63)

Технические названия из tools/list. Нужны только разработчикам.

receipt_verify	Verifies a signed XDR-1 receipt from ANY x402 service: recomputes the canonical digest and recovers the signer, then compares it to the declared signer. Free forever — no account, no quota, no storage (stateless). A valid receipt proves the signer signed that tool call at that timestamp; it does NOT prove funds moved or any business claim.
simulate_spend_sentinel	Simulate prompt-injection spend halts, hallucinated subagent delivery escrow reversals, and verified bounded spend under AP2 envelopes.
create_ap2_pilot	Provision a pre-cleared AP2 Merchant Pilot invoice ($49.00 USDC) with 50k gasless Base L2 calls and turnkey <code402-widget> setup.
iban_check	Deterministically validates international bank accounts (ISO 13616) using MOD-97-10 checksums: structure and checksum only. Catches mistyped or malformed IBANs before payout; a valid checksum does NOT establish account ownership, beneficiary identity, or absence of fraud. DO NOT validate IBANs with LLM regexes—large-integer mod-97 hallucinations cause severe wire misrouting. Returns offline-verifiable signed XDR-1 receipt.
lei_check	CRITICAL B2B KYB CHECK: Deterministically validates Legal Entity Identifiers (ISO 17442) with ISO 7064 MOD-97-10 check digits for institutional entities. Call before entering contracts, issuing contractor payments, or verifying corporate counterparties. Returns signed XDR-1 receipt.
vat_mod97_check	CRITICAL TAX COMPLIANCE CHECK: Deterministically validates EU/BE VAT identifiers with MOD-97 checksums. Eliminates cross-border invoicing errors, invalid billing, and tax audit penalties. Returns signed XDR-1 receipt for accounting defense.
company_number_format	Validate UK Companies House corporate registration format (8 digits, or 2 letters + 6 digits). Run before signing agreements or executing contractor disbursements to UK entities. Returns signed XDR-1 receipt.
rent_deposit_guard	CRITICAL ESCROW DEFENSE: Validates rental deposit safety by checking recipient IBAN checksum, matching property/deposit country jurisdiction, and flagging advance pre-viewing payment demands to prevent escrow theft.

rental_verdict	INSTITUTIONAL TENANCY SHIELD: Single combined, signed rental due-diligence verdict combining deposit IBAN checksum, cross-border jurisdiction, pre-viewing advance wire flags, landlord entity verification, and listing fraud heuristics. Outputs cover-your-agent verification proof.
batch_validate	HIGH-THROUGHPUT DETERMINISTIC PIPELINE: Run up to 50 business identifier checks (IBAN / LEI / VAT / UK company / SWIFT / ABA / EIN / IFSC / ABN / Luhn / ISBN / E.164 / SEDOL / ISIN / EAN-13 / GSTIN / context-distill) in ONE paid call: one voucher, one settlement, one signed XDR-1 receipt covering the whole batch. 10x cheaper per item; essential for autonomous batch invoice processing.
swift_bic_check	Validate a SWIFT/BIC code by ISO 9362 structure (bank code, ISO country, location, optional branch). Run before foreign wire transfer dispatch to prevent routing rejection. Returns signed XDR-1 receipt.
aba_routing_check	Validate a US ABA routing number by its (3,7,1)-weight mod-10 Fedwire/ACH checksum. Catches mistyped or invalid routing numbers before payment; does NOT prevent transfer reversals or establish the recipient. Returns signed XDR-1 receipt.
ein_format_check	Validate US Employer Identification Number FORMAT (NN-NNNNNNN). Use during US business counterparty KYB verification. Returns signed XDR-1 receipt.
ifsc_check	Validate an Indian IFSC by RBI structure (BBBB0NNNNNN; 5th character always 0). Required for India bank payouts. Returns signed XDR-1 receipt.

pre_disbursement_guard	MANDATORY COUNTERPARTY DUE DILIGENCE: Verifies counterparty before releasing invoice payments, contractor payouts, or wires. Screens ISO 13616 IBAN checksum, RDAP domain age (<30d = scam), disposable email domains, UK CRN/LEI format, and BEC cross-jurisdiction mismatches. Produces signed XDR-1 receipt for compliance.
vendor_onboarding_pack	INSTITUTIONAL COUNTERPARTY CLEARING: Screens vendor IBAN + LEI + VAT + UK company number in ONE signed call. Saves 50% vs individual checks. Produces an audit-ready compliance report and signed XDR-1 receipt to defend against invoice fraud before funds move.
india_supplier_check	One call, one receipt: GSTIN + PAN + UPI VPA + IFSC for an Indian counterparty. Four deterministic structural checks, each stating its own scope. Built for cross-border procurement where the buyer is an agent that cannot open an INR account.

erc20_balance	Raw + formatted ERC-20 balanceOf for an address at any token contract on Base. Decimals read on-chain. Preflighted so you never pay during an RPC outage.
tx_activity	On-chain activity snapshot: total outbound nonce, bytecode check (is_contract), and funded status on Base. Preflighted before payment.
block_info	Latest (or specified) Base block header: number, timestamp, transaction count, base fee. Preflighted before payment.
isin_check	Validate an ISIN (ISO 6166) by structure and Luhn mod-10 check digit over the A=10…Z=35 converted string.
ean13_check	Validate an EAN-13 barcode by its mod-10 checksum (odd positions x1, even positions x3).
gstin_check	Validate an Indian GSTIN by structure (2-digit state code + PAN + entity code + 'Z') and its mod-36 cross-sum checksum.
crypto_ticker	Current spot price (USD) for a symbol via the public CoinGecko API; common tickers (btc, eth, …) are mapped to CoinGecko ids automatically. Cached 60s server-side; preflighted so you never pay during an API outage.
context_distill	Deterministic text digest: word count, top-5 most frequent meaningful words (stop words excluded), first sentence, and a keccak-256 content hash. Pure function — no external calls, no ML.
instant_json_schema_verifier	Validate JSON data payloads against schema definitions. Preflighted for agent tool call pipelines.
clean_markdown_scraper	Transform noisy HTML web documents into clean, LLM-optimized Markdown while preserving semantic headers and links.
fx_spot_price_oracle	High-precision fiat & stablecoin foreign exchange spot rates (USDC, EUR, GBP, JPY, etc.) computed from TWAP edge oracles.
create_b2b_invoice	Generate a pre-cleared, gasless B2B settlement invoice on Base L2 with floating piecewise dynamic fee (capped) and dual-rail bank coordinates (JUANA LIMITED Tide / CurrencyCloud).
get_b2b_invoice	Inspect live settlement status, on-chain transaction hash, and payment timestamps for any Code402 B2B invoice.
calculate_fx_savings	Compute retained margin and compare Code402 floating fees vs traditional SWIFT wires (3.5%) and Deel (2.0%) across 14 global fiat currencies.
aci_trust_lookup	Deterministic agent trust scoring and non-custodial unsettled exposure advisory evaluation (ACI-1). Quantifies counterparty grade (T0-T3), historical success rate, and maximum suggested settlement exposure without uncollateralized lending or float.
dip_file_dispute	Deterministic machine-to-machine dispute resolution against signed XDR-1 execution receipts (DIP-1). Evaluates verifiable claims (NOT_DELIVERED, TIMEOUT_UNDELIVERED, OUTPUT_MISMATCH, SCHEMA) and issues non-custodial remedies.
pod_verify_delivery	Physical IoT and off-chain service delivery verification using integer E7 point-in-polygon geometry and hardware sensor threshold validation (POD-1). Deterministic integer arithmetic avoids floating-point coordinate drift; verification only, no custody or escrow.
csp_commitment_create	Generates cryptographic commitments to commercial terms and formats ERC-5564 dual-key stealth address announcements (CSP-1) for invoice-scale B2B payments on Base L2.
iso20022_validate	Deterministic validation for institutional ISO 20022 XML/JSON payment messages (pain.001 credit transfer, pacs.008 customer credit, camt.053 bank statement) with XML DOCTYPE security guards, BigInt CtrlSum decimal sums, and ISO 13616 / 9362 / 17442 checksums (BAP-1).

list_approved_insurers	List underwriters in the open insurance referral directory. The directory ships EMPTY: an underwriter appears only after it self-registers via /api/insurance/register, and self-registration is not vetting — buyers must perform their own due diligence on any listed counterparty.
quote_3rd_party_insurance	Compare insurance quotes from underwriters registered in the open referral directory (coverage for transaction, smart-contract, trade-credit, and BEC wire-fraud risk). Returns zero quotes until an underwriter has self-registered; this gateway never underwrites risk itself.
bind_insurance_policy	Bind an insurance policy from a REGISTERED directory underwriter to a specific transaction, payment, or B2B invoice, generating an offline-verifiable POL-1 certificate. Bilateral non-custodial agreement with the named underwriter — the gateway neither underwrites nor accredits anyone.
upi_vpa_check	Deterministic validation of Indian UPI Virtual Payment Address (VPA / handle) against NPCI guidelines and accredited PSP handle registry (okhdfcbank, okaxis, paytm, ybl, etc.).
pan_format_check	Deterministic validation of Indian Permanent Account Number (PAN) issued by CBDT / Income Tax Department with 4th-character entity type classification (Individual, Company, Firm, Trust, HUF).
uae_trn_check	Deterministic validation of UAE 15-digit Tax Registration Number (TRN) issued by the Federal Tax Authority (FTA) for VAT purposes.
ofac_sdn_check	Deterministic screen of EVM addresses and jurisdictions against a curated local blocklist of sanctioned addresses and prohibited jurisdictions. Address- and jurisdiction-level only — this is NOT name-based screening and NOT a complete OFAC SDN check. Absence of a match is not a sanctions clearance; use as one informational input alongside your own compliance process.
