## 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 omniapi-ai-faq-endpoint-c5ba8d11 -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need quick, structured answers to AI-related questions or terminology lookups without needing to call a full LLM inference API. It is most useful for FAQ-style retrievals where the question is well-known and the answer is expected to be pre-indexed, rather than requiring open-ended generation.

## Known failure modes

- Missing required 'query' field returns a validation error
- Unrecognized or out-of-scope queries may return empty or generic responses
- Payment failure via x402 results in HTTP 402 and no response body
- Service downtime on Vercel hosting may cause 5xx errors
- Malformed JSON request body results in a 400 bad request error
