FAQs

How does billing for the Bing Search APIs work?

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).

What happens if I exceed number of transactions per second (TPS) for a given tier?

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.

What constitutes a transaction for the Bing Search APIs?

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.

Can I change the tier of service I subscribed to?

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.

Has the price of the Bing Search APIs changed?

On February 16, 2023, we announced a price change for all of the Bing Search APIs. The new prices went into effect on May 1, 2023. We periodically assess the value and pricing of our services to meet market demands and align the pricing of our products and services with customer consumption trends and preferences. The new pricing model reflects more accurately the technology investments Bing continues to make to improve Search.

Does Bing Custom Search return the same response across all Tiers?

No, Bing Custom Search is curtailed to meet specific offering of each Tier. For example, Tier S3 is meant for customers wanting to utilize only custom web results and custom image results for their selected set of domains. The S3 Tier also offers statistics capabilities. The API response will differ depending on the endpoint called within a specific tier. Each endpoint has its own response schema.

How does pricing work given there are multiple APIs per Tier?

Tiers are priced based on the number of transactions. As an example, for Tier S3, the price per 1,000 transactions is $6 and for Tier S4, the price per 10,000 transactions is $4. At the end of the billing period, if 20,000 transactions are logged for the Tier S3 and 40,000 transactions are logged for the Tier S4, then the total will be $136 calculated as $6*(20,000/1,000) + $4*(40,000/10,000).

How does the Statistics Feature work?

Statistics is offered as part of Tier S2 and Tier S3. Within 24 hours of doing a Bing Custom Search Web or Image API call using a Tier S2 or Tier S3 key, the charts in your [authoring portal](https://aka.ms/bapisignupcustomsearch) will start populating statistics. You can gather metrics such as call volume, top queries, API response code distribution, and market distribution amongst many others.

How does billing for the Custom Autosuggest feature work?

The Custom Autosuggest feature is offered as a separate tier than Tier S4. Custom Autosuggest can be purchased separately and can be incorporated to get auto suggestions for either S1, S2 or S3 Tiers. For example, if a customer wants to use S1 Tier and S4 tier, they will need to buy both the tiers separately and the billing will work as follows: If in S1 Tier a customer has used a total of 3,000 transactions and in S4 tier if a customer has used a total of 40,000 transactions, then the total billing will be $28 calculated as $4*(3,000/1,000) + $4*(40,000/10,000).
