## When to prefer this

Choose this endpoint when an AI agent needs to verify the factual accuracy of a specific claim using academic or scholarly evidence, especially when scientific, historical, or empirically verifiable assertions are involved. Prefer this over general web search when the goal is rigorous fact-checking against research literature rather than finding web pages.

## Known failure modes

- Missing required 'claim' field returns a validation error
- Missing required 'lang' field returns a validation error
- Unsupported language code may result in an error or degraded results
- Payment failure (insufficient USDC or wrong network) returns HTTP 402
