About this API
Bing Autosuggest is part of the Bing Search API family, designed for search-box type-ahead. When a user types "coff", the API returns ["coffee shops near me", "coffee table", "coffee maker"] — backed by Bing's billions of monthly searches and best-in-class quality for general web suggestions. **Key change: Microsoft announced in 2024 that the entire Bing Search API family (including Autosuggest) will sunset on 2025-08-11.** Migration paths: Azure AI Search (different product), or third-party providers (Algolia, Typesense, custom Elasticsearch with query-log-trained suggesters).
