## How to call it through Zero

```sh
zero fetch --capability api-auor-io-bdc0040d
```

Example prompt: What are all the available filter options I can use when searching for people through CrustData — like what values are valid for job title, industry, or location filters?

## When to prefer this

Use this endpoint before constructing a CrustData people search request to discover which filter values are valid and supported. Prefer this over guessing filter values or hardcoding them, especially when filter options may change over time or when the agent needs to validate user-supplied filter inputs against known enumerated values.

## Known failure modes

- Invalid or unrecognized query parameters return 400 Bad Request
- Payment not provided or insufficient results in 402 Payment Required
- Service unavailable returns 503
- Empty filter list returned if CrustData schema has no filters registered
- Rate limiting may return 429 Too Many Requests
