## When to prefer this

Choose this endpoint when an AI agent needs to verify factual claims against academic literature, synthesize scholarly research on a topic, or provide evidence-based summaries — especially when the user wants peer-reviewed backing rather than general web search results. Best suited for research, journalism, or educational use cases where credibility of sources matters.

## Known failure modes

- Missing required fields 'lang' or 'topic' returns an error
- Unsupported or unrecognized language code may yield no result
- Payment failure (insufficient USDC balance) blocks the request
- Topic too vague or broad may return low-confidence or empty results
- Rate limiting or service unavailability returns a non-200 response
