## 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-academic-fact-checking-research-summary-9cd0e556 -d '<json body>'
```

Example prompt: Can you fact-check the claim that 'coffee reduces the risk of Alzheimer's disease' and give me a research summary in English based on academic sources?

## When to prefer this

Use Canon when an AI agent needs to verify claims or retrieve academically-grounded summaries rather than general web search results. Prefer this over general search endpoints when the user explicitly wants peer-reviewed or scholarly backing, multi-language research output, or structured fact-checking. Less suitable for real-time news or non-academic content.

## Known failure modes

- Missing required field 'topic' or 'lang' returns a validation error
- Unsupported or malformed language code may yield unexpected results
- Payment failure (insufficient USDC balance) blocks access
- Highly niche or very recent topics may return low-confidence or sparse summaries
- Network timeout on the underlying academic search pipeline
