X402 · Audit

Purpose: audit an x402 endpoint for 402/openapi/well-known consistency before listing or paying it. x402 seller self-check (consistency audit) for any paid endpoint: fetches the unpaid 402 and cross-checks PAYMENT-REQUIRED header vs JSON body vs /openapi.json x-payment-info vs /.well-known/x402 listing. Flags price/payTo/method mismatches, resource URL mismatch, non-USDC asset, testnet, missing Bazaar metadata, slow responses. Never pays. Use before listing your endpoint or before paying an unknown one. Failed calls (HTTP 4xx/5xx) are not charged.
