  • Bing Search APIs are invoiced based on number of transactions (also known as API calls). These plans are pay-as-you-go and doesn’t incur additional cost for complex queries and more than 10 results (up to 50 results in most cases).

  • If you happen to exceed the mentioned number of transactions per second (TPS), your usage will be throttled to be within the mentioned limit. If your application needs to have higher TPS than the ones mentioned on this page, please reach out to the Azure support team.

  • For billing purposes, a transaction is a successful Bing API call request (though there are caveats for DoS attacks). For logging and reporting purposes such as for the Bing Statistics Add-in, it is any Bing API call irrespective of whether it is successful or not.

  • You can change the tier of service anytime. Please make sure you use appropriate keys in your API calls. If you are having enterprise agreement with Microsoft, please work with your account executive.
