## 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`):

```

Example prompt: Can you fact-check what happened with the discovery of the Higgs boson on July 4, 2012 — I want verified, sourced information about that event?

## When to prefer this

Choose this endpoint when an AI agent needs to verify factual claims or retrieve academic/event-based information tied to a specific date and topic, especially when source credibility and fact-checking are required. Prefer this over general web search when the use case demands structured, verifiable event data rather than raw web content.

## Known failure modes

- Missing required 'date' or 'topic' field returns a 400-level error
- Unrecognized or ambiguous date format may cause lookup failure
- Topic too vague or broad may return no results or success:false
- Payment not completed or insufficient USDC balance triggers 402 Payment Required
- Server-side research pipeline timeout returns an error or success:false
