## How to call it through Zero

```sh
zero fetch --capability canon-statistics-endpoint-5fa0cce7 -d '<json body>'
```

Example prompt: Can you pull up the key statistics on climate change and sea level rise? I want to fact-check some claims I'm seeing.

## When to prefer this

Use this endpoint when you need quantitative statistics or aggregate data on a research topic for fact-checking or academic purposes, and want results backed by curated academic sources rather than a general web search.

## Known failure modes

- Missing required 'topic' field returns a 400-style error
- Topic too vague or unsupported may return empty or low-confidence results
- Payment failure (402) if USDC payment on Base is not completed
- Server-side lookup failure returns success: false
