常见问题

  • 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.

  • 如果达到免费级别的事务限制,则使用会受到限制。客户无法在免费级别超额使用。

  • 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).

  • 如果在标准级别超额使用,则帐户开始累加超额量。这些超额部分按照为每个级别指定的费率按月计费。

  • 任何 API 调用(批处理评分调用除外)都算作事务。批处理评分调用基于该事务中需评分的项数进行计费。

  • 如果达到免费级别的事务限制,则使用会受到限制。客户无法在免费级别超额使用。免费层不支持批处理评分。

  • 对于建议 API,可以按标准层计价单位以固定价格购买。每个单位的级别都包含一定数量的 API 事务。如果用户使用的数量超出了包含的数量,则超出部分将按上面的定价表中指定的费率收费。这些超出部分按比例计算,而服务按月计费。一个级别中包含的数量会每月重置。

  • 你可以随时升级到较高级别。较高级别对应的计费费率和包括的量将立即生效。

  • 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
    必应 Web 搜索 API https://api.cognitive.microsoft.com/bing/v7.0/search S1-S8
    必应图像搜索 API https://api.cognitive.microsoft.com/bing/v7.0/images/search S1, S3, S7, S8
    必应新闻搜索 API https://api.cognitive.microsoft.com/bing/v7.0/news/search S1, S5, S8
    必应视频搜索 API https://api.cognitive.microsoft.com/bing/v7.0/videos/search S1, S4, S7, S8
    (Preview, EN-US Only)
    https://api.cognitive.microsoft.com/bing/v7.0/entities S1, S6
    Bing Autosuggest API https://api.cognitive.microsoft.com/bing/v7.0/autosuggest S1, S2
    Bing Spell Check API 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*(13,000/1,000).

  • 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.
