Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 docs-to-openapi-skeleton-generator-eb2a208c -d '<json body>'
```

Example prompt: Take my API documentation — it's a markdown file describing endpoints, request params, and response formats for a REST API — and generate an OpenAPI skeleton from it so I can use it as a starting point for a full spec.

## When to prefer this

Use this endpoint when you have existing API documentation in prose, markdown, or other unstructured formats and need a machine-readable OpenAPI skeleton as a starting scaffold. Ideal for bootstrapping OpenAPI spec creation without writing YAML by hand. Prefer this over manual spec authoring or generic LLM prompting when you want a structured, async job-based conversion with a trackable result.

## Known failure modes

- Invalid or unparseable documentation input returns an error status
- Insufficient API description detail may produce an incomplete or empty OpenAPI skeleton
- Payment failure via x402 protocol prevents job creation
- Timeout or processing failure returns a failed status on the job
- Ambiguous documentation with no recognizable endpoint patterns may yield minimal output

## How this service works

Purchase: Docs to OpenAPI Skeleton

## Output

Returns a job_id, a status string indicating processing state, and a thread_id for tracking the async conversion job. The actual OpenAPI skeleton document is likely retrieved separately using the job_id once the job completes.

## Response schema (JSON Schema)
