## 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 blockint-ai-647bf42c
```

Example prompt: Search the C3 community fraud reports database for anything mentioning the wallet address 0xAbC123... or the project name 'QuickSwap Finance' — show me up to 50 results.

## When to prefer this

Use this endpoint when you need free-text search across the entire C3 fraud report corpus — ideal for investigating specific wallet addresses, domains, project names, or crime types across all 64,000+ reports in a single query. Prefer this over the paginated list endpoint when you have a specific keyword or entity to look up rather than browsing all reports by filter.

## Known failure modes

- Missing required query parameter 'q' returns a 400 Bad Request error
- Limit exceeding 100 returns a validation error
- No matching reports returns an empty results array
- Service unavailable or payment failure returns a 402 or 5xx error
- Very broad queries may return noisy or irrelevant results up to the limit
