OpenAPI Specification

openapi: 3.2.0
info:
  title: AI Discovery Site Audit — AEO/GEO Fix Pack | agent402.dev…
  version: 1.7.0
  description: 'Primary product: five fixed remediation slots for JSON-LD, metadata, robots.txt, llms.txt, and sitemap.xml. Copy-paste code is included only when observed evidence permits; otherwise the slot reports an explicit review, none, or needs-input action. Includes a $5, 22-check technical SEO/AEO/GEO audit and seven fixed agent-discovery findings for one public HTTPS page with at least one public IPv4 DNS answer. Existing auxiliary x402 tools remain available on their documented paths.'
  x-guidance: 'Use siteReleaseAudit for the primary $5 AI Discovery Site Audit. First POST the exact body to the free /site-release-audit/eligibility support route; it checks bounded main-document delivery but returns no score, findings, root observations, or remediations. Then submit the unchanged body promptly with an x402-capable buyer client that validates the exact v2 Base-USDC terms and supplies PAYMENT-SIGNATURE. Plain curl is only a 402 probe: it inspects the challenge, is not checkout, and does not pay. Direct x402 cancels settlement on a 4xx/5xx report response; Payan challenges before seller input validation and wrong input can still settle. Inspect GET /site-release-audit/sample.json and GET /site-release-audit/methodology.json for the current v1.1 contract. GET /site-release-audit/proof/v1/case-study.json is the immutable seller-controlled base proof; it predates and does not prove root-file observation.'
