Semantic search API built for models, not for humans.
Use it for
Finding pages by meaning when you do not know the keywords a site would use
Skip it if
Fresh news or exact-match requirements — the index and ranking are not built for that
A search API that embeds queries and pages so retrieval can work on meaning rather than keywords. The useful case is a question phrased the way a person would ask it, where the page that answers it uses different words. It returns contents alongside results, which saves a fetch round trip, and it is priced per request rather than per seat.
