This batch turns Ontario's real verification surfaces into structured decision pages: what to check, when to reject, which API to call, and what evidence an agent should keep before signing an x402 payment.
Only after x402 facilitator integrators can inspect scheme, network, asset contract, payTo address, maxAmountRequired, and facilitator support. If the evidence is missing, stale, or contradictory, the agent should fail closed.
Primary API: /facilitator/supported
Only after agent marketplace operators can inspect benchmark score, payment correctness, price clarity, schema quality, network clarity, and report history. If the evidence is missing, stale, or contradictory, the agent should fail closed.
Primary API: /api/benchmarks?protocol=x402
Only after enterprise procurement teams can inspect report_id, grade, score, timestamp, issues, integrity endpoint, and historical observations. If the evidence is missing, stale, or contradictory, the agent should fail closed.
Primary API: /api/verify/reports
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.
Primary API: /api/x402/list-service/validate
Only after security reviewers can inspect preflight result, endpoint readiness, report history, payment challenge consistency, and fallback policy. If the evidence is missing, stale, or contradictory, the agent should fail closed.
Primary API: /api/agent/can-pay
Only after autonomous agent wallets can inspect target URL, max price, network, report freshness, and policy outcome. If the evidence is missing, stale, or contradictory, the agent should fail closed.
Primary API: /api/agent/can-pay
Only after paid API providers can inspect 402 status, PAYMENT-REQUIRED header shape, accepted requirements, and retry expectations. If the evidence is missing, stale, or contradictory, the agent should fail closed.
Primary API: /api/verify/x402-readiness
Only after paid API providers can inspect normalized listing payload, endpoint URL, owner contact, category, price, and report link. If the evidence is missing, stale, or contradictory, the agent should fail closed.
Primary API: /api/x402/list-service/validate
Only after MCP tool builders can inspect accepts entries, methods, network, asset, price format, facilitator metadata, and freshness. If the evidence is missing, stale, or contradictory, the agent should fail closed.
Primary API: /.well-known/x402.json
Only after autonomous agent wallets can inspect fresh report_id, HTTP 402 behavior, manifest fields, OpenAPI hints, robots access, and remediation warnings. If the evidence is missing, stale, or contradictory, the agent should fail closed.
