Payment path

  • Inspect the recommendation and sample payload.
  • Send the selected POST route without payment if you need to inspect the expected HTTP 402 challenge.
  • Pay the listed route price with a buyer-controlled x402 client on Base mainnet.
  • Retry the exact same POST and expect HTTP 200 with structured JSON.
