## 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-fact-check-academic-research-31df2516 -d '<json body>'
```

Example prompt: Can you fact-check this claim for me: 'Drinking 8 glasses of water per day is scientifically required for good health'? Search academic sources and tell me if it holds up.

## When to prefer this

Use this endpoint when an AI agent needs to verify factual claims against academic literature, check the credibility of a scientific or news claim, or find scholarly sources to support or refute an assertion. Prefer over general web search when academic rigor and source quality matter.

## Known failure modes

- Missing required 'query' field returns validation error
- Empty or very short query may yield no results
- Payment failure (insufficient USDC balance) returns 402
- Claim too ambiguous for reliable verification
- Academic database may not cover niche or very recent topics
