  x-claim-boundary: 'Read-only checks: no test purchase, settlement or paid-delivery verification, code changes, or guaranteed marketplace indexing. Reports are time-bound observations, not launch certification, seller trust, or contract-safety guarantees.'
  x-guidance: 'Use x402 Preflight to check your endpoint before launch or while debugging x402 configuration and client compatibility; buyer-side inspection remains available. Start with inspect_x402_endpoint: POST /api/preflight/inspect is free and read-only. For deeper payment, Bazaar discovery, CORS, redirect and cache evidence, use audit_x402_endpoint: POST /api/x402/preflight/audit with a JSON body. GET /api/x402/preflight/audit is a compatibility alias, not a separate capability; resource_url is required and target method must be GET or HEAD. Only use order_x402_remediation after explicit purchase approval; it creates a durable order for an asynchronous diagnostic report with findings, evidence, and fix recommendations. The receipt is not the completed report, and implementation or human consultation is not included. max_price_usd is a target comparison policy, not our service fee. A price-limit BLOCK does not establish a broken integration; ALLOW is not launch certification. Inputs must be public HTTPS targets. Never include private keys, payment signatures, authorization headers, cookies or access tokens as tool input. The live HTTP 402 challenge overrides advertised pricing. Reports are time-bound observations, not guarantees of settlement, delivery or seller trust. Read-only checks: no test purchase, settlement or paid-delivery verification, code changes, or guaranteed marketplace indexing.'
