Does this x402 endpoint really deliver? x402 Doctor buys it once with the example input its own listing declares (at most $0.1, USDC on Base), checks the answer against the declared output schema and measures the charge on chain. Answers with a job id at once; the result is public, usually within 30 minutes. For sellers who want proof, and buyers before a big order.
