x402 pre-payment decision playbook

Prepare Coinbase Bazaar readiness for Coinbase Bazaar publishers

A service can be payable but still hard for agents to discover or trust. This playbook maps the decision to observable Ontario evidence so an agent can fail closed before payment.

Decision question: Can Coinbase Bazaar publishers rely on this x402 endpoint without listed services that are payable but not agent-readable?

Only after Coinbase Bazaar publishers can inspect service metadata, manifest quality, readiness report, price clarity, and discovery fields. If the evidence is missing, stale, or contradictory, the agent should fail closed.

Required evidence

  • Confirm the endpoint maps to a real payment resource for service teams preparing x402 metadata before marketplace discovery.
  • Require service metadata, manifest quality, readiness report, price clarity, and discovery fields.
  • Reject when there is missing service metadata, broken manifest, no report_id, or no clear payment resource.
  • Link the final decision to a public report, manifest, benchmark row, or policy outcome.

Reject conditions

Reject or send to human review when there is missing service metadata, broken manifest, no report_id, or no clear payment resource.

Do not let a positive-looking badge or directory row override a stale or contradictory live check.

Agent workflow

  1. Start with the no-payment evidence path.
  2. Run the Ontario verifier or policy endpoint shown below.
  3. Compare live endpoint behavior against manifest and discovery metadata.
  4. Store the report_id or policy decision with the agent's payment log.
  5. Send the payment only when the agent's own policy allows it.

Trust boundary

Ontario Protocol provides readiness and trust signals based on observable endpoint behavior, manifest metadata, payment challenge behavior, report history, and public evidence. It does not guarantee endpoint safety, service quality, financial outcome, or future behavior.
