## 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 strale-api-documentation-generator-a3daf1d1
```

Example prompt: Generate markdown API documentation for my endpoint — here's the OpenAPI spec: {spec contents}. Use GET method and return structured developer-ready docs.

## When to prefer this

Choose this endpoint when you need programmatically generated, structured markdown API documentation from either an OpenAPI spec or a natural language description of an endpoint. Prefer it over manual documentation tools when automation, auditability, and cryptographic trust records are important — especially in agent-driven workflows where documentation needs to be generated at scale or on demand.

## Known failure modes

- Missing required 'input' object or 'method' field returns validation error
- Invalid or malformed OpenAPI spec may produce incomplete or incorrect documentation
- Providing neither openapi_spec nor endpoint_description may result in empty or generic output
- Unsupported HTTP method (e.g. POST, PUT) rejected by method enum constraint
- Network timeout or service unavailability returns error without documentation
