StatusUnknown

How this service works

Check OpenAPI 3.0 and 3.1 documents for duplicate operation IDs, broken local references and incomplete definitions. Structured reports over an x402 API.

Output

Returns a JSON object with a status string (e.g. 'no_errors_in_checked_rules'), counts of errors, warnings, operations, and limitations, an array of findings objects with details about each issue, a truncated flag, a limitations array, and the detected OpenAPI and schema versions.

Example use cases

Pre-publish API spec validation

“Before I publish my API docs, can you run a check on my OpenAPI 3.1 spec at https://raw.githubusercontent.com/acme/payments-api/main/openapi.json and tell me if there are any duplicate operationIds or broken local references?”

CI pipeline spec linting

“I want to validate the OpenAPI definition at https://api.swaggerhub.com/apis/myteam/inventory-service/1.0.0 — can you check it for errors, warnings, and any incomplete definitions?”

Petstore example spec audit

“Can you run a validation check on the official Swagger Petstore OpenAPI spec at https://petstore3.swagger.io/api/v3/openapi.json and summarize any issues found?”

When to prefer

Choose this endpoint when you need a fast, structured lint report on a publicly accessible OpenAPI 3.0 or 3.1 document, specifically targeting duplicate operationIds, broken local $ref references, and incomplete definitions. It is ideal for pre-publish checks, CI validation steps, or auditing third-party API specs hosted on GitHub or SwaggerHub. Prefer it over generic OpenAPI validators when you need a machine-readable structured findings array suitable for agent consumption.

Side effects

URL points to a private or inaccessible resource — returns an error or empty findings
Document exceeds 1 MB size limit — rejected with a limit error
URL contains query parameters or redirects — not accepted per constraints
Non-OpenAPI 3.0/3.1 document submitted — may return unsupported version error
Malformed URL format — schema validation failure before any check is performed
YAML/JSON parse failure in the target document — returns parse error in findings
