Autosuggest API - v7

The Autosuggest API lets partners send a partial search query to Bing and get back a list of suggested queries that other users have searched on. In addition to including searches that other users have made, the list may include suggestions based on user intent. For example, if the query string is weather in Lo, the list will include relevant weather suggestions.

Typically, you use this API to support an auto-suggest search box feature. For example, as the user types a query into the search box, you would call this API to populate a drop-down list of suggested query strings. If the user selects a query from the list, you would either send the user to the Bing search results page for the selected query or call the Bing Search API to get the search results and display the results yourself.
