## When to prefer this

Choose this endpoint when you need a finished, cited answer from the live web rather than a raw list of links or a knowledge-cutoff response. It is ideal for fact-checking, recent news research, domain-scoped lookups (e.g. only government or news sites), and any 'what happened with X' question where you need verbatim source quotes as evidence. Prefer it over a raw SERP API when the agent needs to present conclusions, not raw URLs. Prefer it over an LLM with a knowledge cutoff when recency matters or you need traceable citations.

## Known failure modes

- Question is fewer than 3 or more than 500 characters — request rejected
- No live web sources found matching the query and filters — empty or low-confidence answer
- Domain filter too restrictive with no matching indexed content — sparse result
- Since date filters out all relevant sources — answer may be empty or stale
- Service temporarily unavailable or upstream search provider error — HTTP 5xx
- Payment not completed or insufficient funds — x402 payment required error

## How this service works

Cited web answer for AI agents - ask a question, get a short answer with verbatim quotes and source URLs from the live web in one call (neural search + page read + synthesis together). Research, fact check, news since a date, domain-scoped lookups, "what happened with X". Not a raw SERP - a finished, cited answer. POST {question, since?, domains?, max_sources?}. Free sample: /web/example.

## Output

A concise synthesized answer to the question, accompanied by verbatim excerpts from relevant web pages and their source URLs, optionally filtered by publication date and domain. The response is a finished, ready-to-use answer — not a raw list of search results — with citations grounding every claim.
