Knowledge for POST /v1/search
POST /v1/search now accepts "knowledge": "core", which queries licensed data providers in parallel with the web index and returns matching records in results.knowledge. Coverage spans stocks, prices and rates, macroeconomics, company data, sports, politics and government, and weather and climate.
Each knowledge result carries a title, a description holding the value, an attribution array naming the data provider, and an optional as_of date. Up to 25 results come back, limited to those relevant to the query. When none are relevant, results.knowledge is omitted and the response contains web and news results only.
On the VerticalRTK fast set benchmark, accuracy rose from 64.5% (Web Search API with highlights) to 84.2% (with highlights and Knowledge).
Knowledge is included in the base Web Search API rate of $5.00 per 1,000 calls. It is available on POST /v1/search only, and existing requests are unaffected until they set the parameter.
