## 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-and-academic-research-b589102f -d '<json body>'

Example prompt: Can you fact-check this claim for me: 'Drinking coffee reduces the risk of type 2 diabetes' — search for academic papers and tell me whether the evidence supports it?

## When to prefer this

Choose this endpoint when an AI agent needs to verify factual claims, find academic citations, or search peer-reviewed literature on a topic. It is particularly useful for research-heavy workflows where grounding AI-generated content in evidence is critical. Prefer this over generic web search when academic or scientific authority is required.

## Known failure modes

- Missing required 'query' field returns validation error
- Empty or ambiguous query may return low-confidence or no results
- Payment failure (insufficient USDC balance) blocks the request
- Service unavailable if the underlying academic database is unreachable
- Very niche or obscure claims may return no corroborating sources
