## 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-checking-academic-research-e88f5b92 -d '<json body>'
```

Example prompt: Can you fact-check this claim for me using Canon: 'Drinking eight glasses of water a day is scientifically required for good health' — I want to know if it's actually supported by research?

## When to prefer this

Choose this endpoint when an AI agent needs to verify factual claims against academic or authoritative sources, especially for research-backed validation rather than general web search. Ideal for checking statistics, scientific assertions, or historical facts where source credibility matters. Prefer over general web search when the task requires academic rigor or misinformation detection.

## Known failure modes

- Missing 'query' field returns validation error
- Vague or ambiguous queries may yield low-confidence results
- Payment failure (insufficient USDC on Base) results in 402 response
- Queries about very recent events may lack academic coverage
- Network timeout on complex multi-source lookups
