Costs $0.01. Use this to grade an endpoint before trusting/publishing it; use settlement_assurance instead when you already have a transaction hash and want to prove a completed PAYMENT settled correctly.

  Parameters:

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

Costs $0.03. This is the most complete post-payment check; use payment_proof if you only need a plain pass/fail, tx_status for raw status, or x402_audit to grade a seller endpoint by URL (no payment yet).
