## When to prefer this

Use this endpoint when an AI agent needs to verify factual claims or retrieve academic/scholarly research on a topic anchored to a specific date. Prefer it over general web search when accuracy, sourcing, and academic credibility are important, especially for research assistance, journalism support, or fact-checking workflows.

## Known failure modes

- Missing required fields (date or topic) returns a validation error
- Topic too vague or broad may return no results or low-confidence matches
- Date out of supported range may return an error or empty results
- Payment failure (insufficient USDC on Base) blocks the request
- Network or upstream academic database outage returns a failure response
