Partners who subscribe to the S15 or S 17 instance will be charged the S15 or the S17 rate up to 1M queries per day. If you believe you may only exceed the 1M per day transaction limit occasionally, we recommend subscribing to both S15 and S16 or if using Custom Search S17 and S18. You should implement monitoring so you can automatically switch to the S16 or S18 instance once you have exceeded your daily limit.
Partners who subscribe only to the S16 or the S18 instance will be charged the S16 or the S18 rate for every transaction made on that instance.
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 are subscribed to the S15 instance and you make more than 1M queries in a 24-hour period, Bing may return a 403 error message that the caller exceeded their transactions per day quota. You can read more about error codes at Error codes used by the Bing Web Search API - Bing Services | Microsoft Learn.
- Partners who subscribe only to the S16 instance will be charged the S16 rate for every transaction made on that instance.
- Partners who subscribe to the S15 instance will be charged the S15 rate up to 1M queries per day. If you believe you may only exceed the 1M per day transaction limit occasionally, we recommend subscribing to both S15 and S16 and implementing monitoring so you can automatically switch to the S16 instance once you have exceeded your daily limit.
If you happen to exceed the mentioned number of transactions per second (TPS), your usage will be throttled and you will see an associated error code. You can find information on error codes in the documentation for each API.
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.
