## 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-summary-b1b81597 -d '<json body>'
```

Example prompt: Can you fact-check this claim for me: 'Moderate coffee consumption reduces the risk of type 2 diabetes' — search the academic literature on that topic and give me a summary in English.

## When to prefer this

Use this endpoint when an AI agent needs to verify factual claims or retrieve summarized academic research on a topic, especially when the agent requires a lightweight per-call micropayment model (USDC on Base via x402) rather than a subscription. Prefer over general web search when scholarly accuracy and fact-verification are the primary goals.

## Known failure modes

- Missing required fields 'lang' or 'topic' returns an error
- Unsupported language code may yield no results or an error
- Obscure or highly niche topics may return limited academic coverage
- Payment failure via x402/USDC on Base prevents the call from completing
- Network or upstream academic database errors may cause success: false
