## 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 orbonomy-fact-check-search-ac2fb6c0 -d '<json body>'
```

Example prompt: Can you fact-check the claim that 'the moon landing was faked' and return the top 5 results from the Orbonomy fact-check search?

## When to prefer this

Use this endpoint when you need to programmatically search a fact-checking database for verified claims about a specific topic, statement, or news story. Prefer this over general web search when you specifically want fact-checked, verified content rather than raw search results. Good for misinformation detection workflows, journalism tools, or content moderation pipelines.

## Known failure modes

- Missing required fields (query or limit) returns a 400-level error
- Query returns no results if no fact-checks exist for the topic
- Payment failure via x402 protocol blocks the request
- Rate limiting or quota exceeded errors
- Malformed input schema causes rejection
