The analysis is delivered only by POSTing {\"url\": \"<spec URL>\"} to https://agent.prh.news/v1/check with an x402-aware HTTP client: the endpoint replies HTTP 402 with x402 v2 requirements (0.10 USDC, Base mainnet, exact scheme); pay and retry the same request to receive the JSON and Markdown change report. Call compare_openapi for the immediate stateless 0.25 USDC before/after product. The canonical service contract is https://agent.prh.news/openapi.json.

      "description": "Developer tool for OpenAPI audit, API analysis, Swagger analysis, and API contract change validation (not general OpenAPI conformance linting). The paid analysis detects breaking changes and API drift by comparing a public OpenAPI/Swagger JSON or YAML contract with the service's last stored snapshot of that URL (the first check records the baseline). It returns deterministic JSON classifying endpoint, method, media-type, status, request/response field, type, requiredness, and structural oneOf/anyOf branch changes as breaking, potentially breaking, non-breaking or informational, plus a Markdown summary. It does not infer schema satisfiability or branch overlap; not and external references are unsupported. Cost: 0.10 USDC per completed analysis via x402 on Base (eip155:8453), settled only after the analysis is computed. This MCP tool itself is free: it validates the URL and returns the x402 endpoint and payment terms; it does not run the analysis or move funds. Canonical service OpenAPI: https://agent.prh.news/openapi.json. To get the analysis, POST {\"url\": \"<spec URL>\"} to the returned endpoint with an x402-capable HTTP client.",
