## When to prefer this

Choose this endpoint when you need a synthesized, evidence-backed answer to a natural-language question with source citations included — particularly when you need verifiable references rather than a raw LLM response. Prefer it over generic LLM completions when grounding in live or recent web content matters, and over raw search APIs when you want a pre-synthesized answer rather than a list of links to process yourself.

## Known failure modes

- Empty or missing question field returns validation error
- Question too vague may produce low-confidence or generic answer
- Web sources unavailable for highly niche topics may result in incomplete answer
- Rate limiting or payment failure returns 402 Payment Required
- Network timeouts on slow or complex research queries
