## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability taskcraft-openapi-check-981f896c
```

Example prompt: Can you check my OpenAPI spec for duplicate operation IDs and broken references? The raw file is at https://raw.githubusercontent.com/myorg/myrepo/main/openapi.yaml

## When to prefer this

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.

## Known failure modes

- 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

## 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.
