Answer API

Answer in brief

An API that returns a direct answer to a question, usually with the sources or quotes behind it, instead of a list of links.

What it means

An answer API takes a question and returns a short reply, often with citations. Some return passages copied from source pages, and some return a generated summary. The answer is shorter than a results page, so an agent can use it without reading dozens of links.

Quality depends on how the sources are checked. Hyperresearch Answers returns one short answer with quotes matched word for word against their pages, or a plain not found, and that is the behavior we use as the reference here. Ask any vendor how it checks quotes before you rely on its answers, and test a sample of them against the source pages yourself. Look at how often the answer is a plain not found, since that is a useful sign of coverage.
