Cognitive Services pricing—Bing Search API

Use intelligence APIs to enable vision, speech, language, and knowledge capabilities

Get enhanced search details from billions of web documents. Retrieve web documents indexed by Bing and narrow down the results by result type, freshness, and more.

The Bing Search APIs add intelligent search to your app, combing hundreds of billions of webpages, images, videos, and news to provide relevant results with no ad requirements. The results can be automatically customized to your users' locations or markets, increasing relevancy by staying local.

Bing Search APIs are available as part of the following Bing Search plans that provide greater value and flexibility.

FAQ

Bing Search API

  • Below table provides a list of available end-points for each API. The response for the same end-point of Bing Web Search API may vary depending on the Tier purchased. Refer to the next question for details.

    Included APIs Endpoints Available in Tiers
    Bing Web Search https://api.cognitive.microsoft.com/bing/v7.0/search S1-S8
    Bing Image Search https://api.cognitive.microsoft.com/bing/v7.0/images/search S1, S3, S7, S8
    Bing News Search https://api.cognitive.microsoft.com/bing/v7.0/news/search S1, S5, S8
    Bing Video Search https://api.cognitive.microsoft.com/bing/v7.0/videos/search S1, S4, S7, S8
    https://api.cognitive.microsoft.com/bing/v7.0/entities S1, S6
    Bing Autosuggest https://api.cognitive.microsoft.com/bing/v7.0/Suggestions S1, S2
    Bing Spell Check https://api.cognitive.microsoft.com/bing/v7.0/spellcheck S1, S2
  • No, the Bing Web Search API is curtailed to meet specific offering of each Tier. For example, Tier S3 is meant for customers wanting to utilize only web search results and images in their applications. The customers also have an option of calling just a specific end point within a tier and their transactions will count against the overall bundle transactions (for example in Tier S3 a customer can just call Image API end point and make 400 transactions and can call Web Search API end point for 600 transactions and the total will be counted as 1,000 transactions).

  • No, both the APIs could potentially return different results even if you are only looking for images. For example, for a certain type of query, Bing Web Search API may return a combination of web results, videos, news but may not return images. However, for the same query, Bing Image Search API may return images.

  • Tiers are priced based on the number of transactions. As an example, for Tier S3, price per 1,000 transactions is $4. At the end of billing period if 12,000 transactions are logged for the Bing Web Search API and 1,000 transactions are logged for the Bing Image Search API, then you will have billed for $52 calculated as $4*(13,000/1000).

  • Bing Spell Check and Bing Autosuggest APIs are billed at 25,000 transactions increment in Tier S1. Whereas, other APIs are billed at 1,000 transactions increment in Tier S1.

    For example, if you are subscribed to Tier S1 and at the end of the billing period 15,000 transactions are logged for the Bing Web Search API, 3,000 transactions logged for Bing Video Search API, and 25,000 for Bing Autosuggest API. In this case, the approximate bill would be $133 calculated by $7*((15,000+3,000)/1,000) + $7*(25,000/25,000).

    Note: For billing, only the end-point is considered and not the requested response. For example, calling the Bing Web Search API only for image response will be counted towards the Bing Web Search API and not towards the Bing Image Search API.

  • Bing Statistics is an add-in that you can purchase from Azure Portal along with one of the S1 to S9 Tiers of Bing APIs. This add-in is charged at $1 per 1 unit of subscribed Tier. For example, if you subscribe to S1 Tier with the Bing Statistics Add-in and make 2,000 calls to the Bing Web Search API and 25,000 calls to Bing Spell Check, you will be charged $24 for 3 units - 2 for Bing Web Search API and 1 for Bing Spell Check - including $1 extra on top of $7 price of the Bing S1 bundle.

  • Bing Statistics Add-in is only available with the Bing APIs' Tiers S1 to S9. It is not available for the standalone API offerings. However, Bing Statistics does provide metrics for all the endpoints included in various Tiers. It is also not available for any other APIs on Cognitive Services apart from the Bing APIs (through S1 to S9 Tiers).

General

  • 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 analyzed. The billing is prorated 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 prorated, 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.
