## 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-entity-fact-check-academic-research-3121e990 -d '<json body>'
```

Example prompt: Can you fact-check the entity with ID 'Q42' using Canon and tell me what academic papers or verified claims are associated with it?

## When to prefer this

Use Canon when an AI agent needs to verify factual claims or retrieve academic/journal content tied to a specific entity identifier. Prefer this over general web search when authoritative, structured fact-checking output is needed and the entity can be referenced by a known ID. Ideal for research pipelines, misinformation detection, and academic citation workflows.

## Known failure modes

- Missing or invalid entity ID returns an error or empty result
- Unknown entity ID with no matching record returns success:false
- Payment failure over x402/USDC on Base blocks the request
- Malformed request body (missing required 'id' field) returns a 400-level error
- Rate limiting or quota exceeded returns a 429 response
