lion_declare_needFREE. The primary way agents bootstrap research on Base. Tell LION a clear, specific need in plain language (e.g. "pre-trade risk + holder concentration for Base memecoins"). LION records it, returns an immediate useful free Quick Intel sample (now with sample_enrichment_vector + tx_context_teaser for stronger value preview), and gives the exact paid upgrade path to the $0.005 flagship bundle (full numeric vectors + decoded tx receipt + calldata + volume + credits). Always include &ref= for conversion tracking from free to paid. Start free, get value, pay only when you need depth. Recommended flow: declare_need -> quick_intel sample -> paid bundle or credits.
lion_quick_intelFREE. Zero-commitment sample of LION quality. Returns compact attention_score + momentum + signals + sample_enrichment_vector preview + tx_context_teaser for any entity. Every response includes the exact machine-actionable upgrade to the $0.005 flagship bundle (full numeric vectors + decoded tx receipt + calldata + volume tiers + credits repeat).

lion_composite_bundleTHE MULTI-CHAIN KEYLESS RPC for AI agents - keyless onchain reads on BOTH Base (eip155:8453) AND Ethereum (eip155:1), no API key, in ONE call - PLUS Ed25519-attested company enrichment as a verifiable trust moat. A broader, verifiable alternative to Ethereum-only keyless RPC (e.g. OneSource). Onchain: pass address=0x... (native balance + contract flag) and/or tx=0x... (receipt: status/block/from/to); add chain=base (default) | ethereum | both. Enrichment: pass identifier=<domain|name|ticker> (+ fields or format=apollo_org) for firmographics (Wikidata CC0) + financials (SEC EDGAR), each field source-labeled + confidence-scored, the whole body Ed25519-attested (verify offline via ?verify_helper=1). Granular in-band pricing in ONE invoice: flat-rate 0.001 USDC per onchain read (per chain) + pay-per-field 0.002 USDC per enrich field (band $0.001-$0.05). Keyless x402 on Base (payment always USDC on Base); company/org-level + public onchain facts only, no PII.

lion_enrich_v1VERIFIABLE keyless company/org enrichment - unlike black-box aggregators, every response is cryptographically ATTESTED (Ed25519 over a SHA-256 of the body; verify offline via ?verify_helper=1) so your agent can PROVE the data is untampered, and every field carries an explicit source + confidence. Field-granular: name ONLY the fields you need and pay only for those (0.002 USDC per field on Base, vs flat-bundle incumbents). Each requested field returns {value, confidence 0-1, source, as_of}. Available fields (expanded 2026-06 for better coverage+conversion): firmographics (inception_year, employees, country, industry, parent_org, stock_exchanges, legal_form, website, description, employees_count, employees_as_of, industry_list, stock_exchanges_list, legal_form_detail) from Wikidata CC0; financials (cik, sic_industry, exchanges, fiscal_year_end, state_of_incorporation, revenue_usd, net_income_usd, total_assets_usd, recent_filings) from SEC EDGAR; web-attention (attention_score, momentum, mention_count). Clearer attested output: top-level .attestation (alg/signer/verify_helper_url/note) + .sources_covered on 200 bodies for agent moat parsing. Use a company NAME for firmographic/web fields, a US TICKER for financial fields. Keyless, no API key, no signup; company/org-level public data only, no PII.

lion_keyless_base_rpcThe MULTI-CHAIN keyless RPC for agents - delete the API key. POST a standard JSON-RPC request (single or batch up to 10) of READ-ONLY methods (eth_call, eth_getBalance, eth_getCode, eth_getLogs, eth_blockNumber, eth_getTransactionReceipt, etc.). Reads BOTH Base (default) AND Ethereum mainnet - add chain=ethereum (query string ?chain=ethereum) to read Ethereum (eip155:1). LION forwards across a free public RPC failover set for that chain and returns the JSON-RPC reply, plus decoded_events (labeled ERC-20/721 Transfer/Approval) for any eth_getLogs. No API key, no signup, no node. Read-only; write methods rejected before payment. GRANULAR per-method pricing (matches/beats granular incumbents like OneSource): eth_blockNumber/eth_chainId $0.001; eth_getBalance/eth_getCode/eth_getTransactionCount $0.002; eth_call/eth_getTransactionReceipt $0.003; eth_getLogs $0.005; batch = sum of its methods. Broader than an Ethereum-only keyless RPC. Payment is always USDC on Base. Pay-per-call via x402, or prepay once (lion_credits_purchase) and call with Authorization: Bearer lct_... with no new signing.
