## 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-1e9f5619 -d '<json body>'
```

Example prompt: Can you fact-check the claim that 'coffee consumption reduces Alzheimer's risk' using Canon and look up any academic research supporting or refuting it — the entity ID is claim-alzheimer-coffee-2024?

## When to prefer this

Choose this endpoint when an AI agent needs to verify factual claims or retrieve academic/journal research by a known entity ID, especially when the use case demands scholarly credibility at low per-call cost ($0.05 USDC). Prefer this over general web search when you need structured, fact-checked, or peer-reviewed sourcing.

## Known failure modes

- Missing required 'id' field returns a 400 validation error
- Unknown or invalid entity ID returns a not-found or empty result
- Payment not provided or insufficient USDC triggers a 402 Payment Required response
- Network timeout or service unavailability returns a 5xx error
- Malformed JSON body causes a parse error response
