## 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 canon-geography-fact-check-a64772ed -d '<json body>'
```

Example prompt: Can you fact-check the geographic details about the Sahara Desert — like its size, location, and which countries it spans?

## When to prefer this

Use this endpoint when an AI agent needs to verify or retrieve accurate, fact-checked geographic information about a specific location and accuracy is critical. Prefer over general web search when you need academically sourced or verified geographic data rather than unverified web content.

## Known failure modes

- Missing required 'location' field returns a validation error
- Unknown or ambiguous location string may return no results or a failure response
- Payment failure (insufficient USDC on Base) results in a 402 Payment Required response
- Network timeout if the research pipeline takes too long
- Malformed request body returns a 400 Bad Request
