## How to call it through Zero

```sh
zero fetch --capability sitesignal-docs-to-openapi-b8d79d90
```

Example prompt: Can you pull the public API docs at https://stripe.com/docs/api and extract all the observed API operations into an OpenAPI JSON draft — don't invent any schemas, just what's actually documented there?

## When to prefer this

Choose this endpoint when you need a machine-readable OpenAPI draft grounded strictly in what a public documentation page actually says — ideal for integrating with third-party APIs that lack an official OpenAPI spec, auditing API surface area, or bootstrapping client generation. Prefer it over manual spec authoring or LLM hallucination when accuracy and source-fidelity matter. Not suitable for private or auth-gated documentation.

## Known failure modes

- Documentation URL is not publicly accessible or returns non-200 response
- Documentation page contains no recognizable API operations
- URL points to non-documentation content (e.g. marketing page)
- Rate limiting or bot protection on the target docs site blocks access
- Output truncated if documentation is very large and exceeds bounded fetch limits
- Invalid docsUrl format triggers schema validation error

## How this service works

Extract source-observed API operations from public documentation into a conservative OpenAPI draft without inventing schemas.

## Output

Returns a conservative OpenAPI draft (JSON or YAML) containing only API operations explicitly observed in the provided public documentation, including paths, HTTP methods, and schemas found in the source — without hallucinating or inventing missing details.
