## 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 sitesignal-openapi-json-inventory-f672de17
```

Example prompt: Can you inventory the OpenAPI spec at https://petstore3.swagger.io/api/v3/openapi.json and tell me all the operations, schemas, security declarations, and any documentation gaps?

## When to prefer this

Choose this endpoint when you need a structured audit or summary of a public OpenAPI 3.x or Swagger 2.0 JSON document — particularly for identifying documentation gaps, security declarations, and available operations — without manually parsing the spec. Prefer this over generic web scrapers or metadata extractors when the target is specifically an OpenAPI/Swagger JSON file and you need API-domain-aware analysis.

## Known failure modes

- Invalid or unreachable URL returns an error indicating the document could not be fetched
- Non-OpenAPI or malformed JSON at the URL results in a parse failure
- Swagger 2.0 or OpenAPI 3.x documents outside supported versions may produce incomplete results
- Very large OpenAPI documents may be truncated or partially inventoried
- Private/authenticated URLs will fail since only public documents are supported

## How this service works

Inventory operations, schemas, security declarations, tags, and documentation gaps in one public OpenAPI JSON document.

## Output

Returns a structured inventory of the target OpenAPI document including: all API operations with their HTTP methods and paths, schema definitions, security schemes and declarations, tags, and identified documentation gaps or missing fields.
