Input: a transaction hash. Returns strict JSON: summary (1-3 sentences), action_type (swap, erc20_transfer, nft_mint, bridge_out, approval_for_all, ...), assets_moved[] (token, amount, from, to), counterparties[] (labeled where known: routers, bridges, marketplaces), risk_flags[] (unverified_contract, unlimited_approval, approval_for_all, known_drainer, first_time_counterparty, nonstandard_token_symbol, impersonated_token, transaction_reverted), checks, gas_paid_usd, timestamp, basescan_url. Risk checks fail open, so read `checks` before drawing any conclusion from an empty risk_flags: it reports whether each check ran (ok / partial / unavailable / inconclusive / not_applicable), and no flags alongside a non-ok status means not checked, not clean. Deterministic onchain decode - no LLM in the response path. Base mainnet (chain id 8453) only. PRICING: 50 free calls per IP per 24h - shared by everyone behind one address - then $0.02 in USDC on Base via x402 - attach payment at _meta['x402/payment'] and retry, or use POST /explain over plain HTTP with any x402 client. Heavy use: $9 buys a 30-day pass (10,000 calls) via the buy_pass tool or POST /pass. No account, no API key.
