ProofDesk — Launch QA API for agents

# ProofDesk Launch Audit API > Deterministic source-level launch QA and declared metadata extraction for HTTPS pages on a temporary managed-host allowlist. No account or API key. Pay per request through x402 v2. ## Canonical resources - Public API: https://proofdesk-audit-api.konstanta-work-x.chatgpt.site - Source and assisted orders: https://github.com/SpaleRuby/proofdesk-audit-api - OpenAPI 3.1: https://proofdesk-audit-api.konstanta-work-x.chatgpt.site/openapi.json - Free example response: https://proofdesk-audit-api.konstanta-work-x.chatgpt.site/api/example - Health: https://proofdesk-audit-api.konstanta-work-x.chatgpt.site/api/health ## Paid endpoints ### Full launch audit — $0.04 USDC POST https://proofdesk-audit-api.konstanta-work-x.chatgpt.site/api/audit Content-Type: application/json Body: {"url":"https://example.com"} An unpaid request returns HTTP 402 and a PAYMENT-REQUIRED header. Payment options are $0.04 USDC on Base mainnet or Solana mainnet. The response is JSON with a score, pass/warn/fail counts, evidence, prioritized fixes, and a bounded same-host link sample. The report checks technical SEO and launch-readiness signals including title and description metadata, canonical and social tags, meta robots directives, page structure, and links. ### Declared metadata extraction — $0.01 USDC POST https://proofdesk-audit-api.konstanta-work-x.chatgpt.site/api/metadata Content-Type: application/json Body: {"url":"https://example.com"} The metadata endpoint returns the title, description, canonical, language, viewport, meta robots, favicon, Open Graph, and Twitter Card values declared in the fetched HTML source. Missing declarations are returned as null and listed in missingFields. It does not render JavaScript, fetch linked assets, probe links, or emulate a social platform preview. ## Scope For temporary network-safety containment, the URL hostname must be one of these provider-owned managed-hosting domains or a subdomain: github.io, pages.dev
