How this service works
Use to detect breaking changes and API drift in a public OpenAPI/Swagger spec (JSON or YAML URL). Compares the spec with the service's last stored snapshot of that URL (first check records the baseline) and returns a deterministic JSON change report plus a Markdown summary. 0.10 USDC per completed analysis.
Output
A deterministic JSON change report listing all detected additions, removals, modifications, and breaking changes between the current spec and the stored snapshot, plus a human-readable Markdown summary. On the first call for a given URL, the spec is recorded as the baseline and the report indicates no prior version to compare against.
Example use cases
CI gate for API breaking changes
“Before I merge this PR, check https://api.myservice.com/openapi.yaml for breaking changes against the last recorded snapshot and tell me if anything is incompatible.”
Weekly API drift monitoring
“Run a drift check on https://petstore.swagger.io/v2/swagger.json and give me a Markdown summary of everything that changed since the baseline was recorded.”
First-time API spec baseline
“I want to start tracking my API for drift — can you run an initial snapshot on https://api.example.com/v1/openapi.json so I have a baseline to compare against going forward?”
Technical details
Endpoint
POSThttps://agent.prh.news/v1/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, structured change detection between two versions of a public OpenAPI or Swagger spec without maintaining your own diffing infrastructure. It is ideal for CI/CD pipelines, automated API governance workflows, or scheduled monitoring jobs where a canonical JSON diff and Markdown summary are required. Prefer it over manual diff tools when you want automatic baseline management — the first call records the snapshot so subsequent calls always compare against the last known state.
Side effects
- URL is not publicly accessible or requires authentication — returns error indicating inaccessible spec
- URL does not point to a valid OpenAPI/Swagger JSON or YAML document — returns parse error
- Network timeout fetching the remote spec URL — returns fetch failure
- Payment not completed (x402 protocol) — request not processed
- Invalid URL format or query string included — returns validation error
