Whether you’re searching the web or a local set of data, or just asking users to enter an input into your app, the Bing Autosuggest API helps narrow the search quickly by allowing your users to see suggestions for popular search terms. It can correct perceived mistakes, and returns detailed contextual suggestions according to other searches that people have found useful.

Support and SLA

  • Free billing and subscription management support are included.
  • We guarantee that Cognitive Services running in the standard tier will be available at least 99.9 per cent of the time. No SLA is provided for the free tier. Read the SLA


  • The Emotion API, Face API, Language Understanding Intelligent Service API, Bing Speech-to-Text API and Bing Text-to-Speech API are billed per 1,000 API transaction calls when a production API call is being actively executed. Billing is prorated for production API transaction call quantities.

    The Bing Long Form Speech API service is billed per hour of speech that is analysed. The billing is pro-rated on a per-minute basis.

    The Recommendations API and Text Analytics API can be purchased in units of the standard tiers at a fixed price. Each unit of a tier comes with included quantities of API transactions. If the user exceeds the included quantities, overages are charged at the rate specified in the pricing table above. These overages are pro-rated, and the service is billed on a monthly basis. The included quantities in a tier are reset each month.

  • Usage is throttled if the transaction limit is reached on the free tier. Customers can’t accrue overages on the free tier.

  • Any annotation to a document counts as a transaction. Batch scoring calls will also take into consideration the number of documents that need to be scored in that transaction. So for instance, if 1,000 documents are sent for sentiment analysis in a single API call, that will count for 1,000 transactions. If an API supports more than one annotation operation, that will also be considered. Let’s say an API call performs both sentiment analysis and key-phrase extraction on 1,000 documents, that will count for 2,000 transactions (2 annotations × 1,000 documents).

  • If the usage on a standard tier is exceeded, the account starts to accrue overages. These overages are billed on a monthly basis and are calculated at the rate specified for each tier.

  • You may upgrade to a higher tier at any time. The billing rate and included quantities corresponding to the higher tier will begin immediately.
