## When to prefer this

Choose this endpoint when you need a natural-language answer to a question that requires current, real-world web data rather than static knowledge. It is ideal for questions about recent events, live market conditions, regulatory updates, or any topic where freshness and grounded citations matter. Prefer it over a raw web search endpoint when you want a synthesized, readable answer rather than a list of URLs or snippets, and over a general LLM when you need the answer to reflect live web content rather than training data.

## Known failure modes

- Empty or ambiguous query returns a vague or unhelpful answer
- Topics with very limited web coverage may yield low-confidence responses
- Rate limiting or payment failure returns a 402 or 429 error
- Very recent events (seconds ago) may not yet be indexed by the web search layer
- Queries that are too broad may return a generalized answer lacking specificity
