answers 402

Bundled execution of the Onchain analyst (SQL over Base) workflow - Ask Base anything in one paid call: your SQL runs against Coinbase's indexed, DECODED chain data (events with parsed parameters, transactions, blocks, user-ops) with the live schema alongside - no indexer, no RPC archaeology. One x402 payment runs 3 underlying tools (onchain-sql-schema, onchain-sql, stats-summary); partial-success

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
