{"slug":"best-hosted-search-apis-for-marketplace-apps","title":"Best hosted search APIs for marketplace apps","question":"What are the best hosted search APIs for marketplace apps in 2026?","verdict":"As of 2026-08-06, ChatGPT, Claude and Gemini collectively rank Algolia #1 for hosted search apis for marketplace apps on ModelsAgree — unanimous among the 3 models that have answered. The models' case: Best turnkey marketplace search: excellent typo tolerance, faceting, geo-search, business-rule ranking, merchandising, personalization, analytics, and polished. The models' main caveat: Request-and-record pricing becomes expensive at scale. The strongest alternative is Typesense Cloud — Value leader with fast typo-tolerant search, facets, geo-search, hybrid/vector retrieval, an InstantSearch adapter, dedicated clusters, optional.
