## When to prefer this

Choose this endpoint when an AI agent needs to verify factual claims or retrieve academically-grounded research summaries, especially for scientific, medical, or historical topics where accuracy and sourcing matter. It is particularly suited for tasks requiring trust and citation-backed information rather than general web search results.

## Known failure modes

- Missing required fields (lang or topic) returns a validation error
- Unsupported language code may return an error or empty result
- Payment failure via x402/USDC blocks the request
- Ambiguous or too-broad topic may return a low-quality or generic summary
- Service unavailability on orbonomy.xyz returns a 5xx error
