Answer API for Cited Answers from a Single Query
The Answer API (POST /v1/answer) returns a synthesized, citation-backed answer to a question in one call. It retrieves web results from a single search, verifies citations against the source text, and returns a Markdown answer with inline citations — no orchestrating retrieval, page reads, prompts, or model selection on your end. It is designed to be focused and fast.
There are no effort tiers to tune, so latency and cost stay predictable across queries. On SimpleQA, the Answer API reports 93.48% accuracy at a p50 of 2.67 seconds, priced at $5.00 per 1,000 calls.
It accepts the same search controls as the Web Search API — freshness, country, language, include_domains, exclude_domains, and boost_domains — and every response includes the answer, the citations with verbatim excerpts, and the web results considered during synthesis.
