## 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-f565d62d -d '<json body>'
```

Example prompt: Can you fact-check this claim for me: 'Coffee consumption reduces the risk of Alzheimer's disease by 65%'? I want to know if this is supported by academic research.

## When to prefer this

Choose this endpoint when an AI agent needs to verify the factual accuracy of a specific claim against academic literature, or when the user wants peer-reviewed sources rather than general web search results. Particularly useful for scientific, medical, or statistical claims where credibility and sourcing matter.

## Known failure modes

- Missing required 'query' field returns a 400 or error response
- Query too vague or ambiguous may return low-confidence results
- Payment failure (insufficient USDC or network issues on Base) returns 402
- Service unavailable returns 5xx
- Very niche or cutting-edge claims may lack academic coverage
