Support and SLA

  • Free billing and subscription management support are included.
  • We guarantee that Cognitive Services running in the standard tier will be available at least 99.9 per cent of the time. No SLA is provided for the free trial. Read the SLA


  • Please refer to the documentation for more detailed descriptions of these Computer Vision features.

    • Adult – Detects adult/racy content to enable automated restriction in images.
    • Analyse – Calls multiple features at once. Specify which features you want to run and the API will run all of these together. Each feature included in “Analyse” will be counted as a separate transaction.
    • Celebrity – Recognises 200,000 celebrities from business, politics, sports and entertainment around the world.
    • Colour – Extracts colours from an image. The colours are analysed in three different contexts: foreground, background and whole. The colours are grouped into 12 dominant accent colours.
    • Face – Analyses human faces within an image.
    • GetThumbnail – Generates a high-quality thumbnail after an image is uploaded. It analyses the objects within the image, then crops the image to fit the requirements of the region of interest (ROI).
    • Image type – Indicates whether an image is black and white or colour, as well as use the same method to indicate whether an image is a line drawing or not. Indicates whether an image is clipart or not, and the quality.
    • OCR & Read – Both features apply optical character recognition (OCR) technology for detecting text in an image, which can be extracted for multiple purposes. The Read feature delivers highest accuracy for printed and handwritten text extraction. Please refer to Documentation for supported languages for OCR and Read.
    • Spatial analysis – Understand how people move through a physical space in near-real time.
    • Tag – Returns tags based on more than 2,000 recognisable objects, living beings, scenery and actions. In cases where tags may be ambiguous or not commonly known, the API response provides “hints” to clarify the meaning of the tag.
  • Each feature you select is counted as a transaction. There are a few special cases to note:

    1. Analyse allows you to select multiple features at once. For instance, an Analyse call specifying the Tag, Face and Adult features would count as three transactions.
    2. Read allows you to upload multipage PDF documents. Each page is counted as a feature. For instance, a 200-page document would count as 200 transactions.
    3. All GET calls to see the results of the async Read and Recognise text features are counted as transactions but are free of charge.
  • Each operation that you call (either individually or through “Analyse”) will be counted as a transaction. The total bill will be based on the number of transactions for each type of operation within a monthly billing period.

    As a specific example, let’s say you make the following calls in a certain monthly billing period:

    • 1,500,000 Analyse operations, each calling both Tag and Describe operations
    • 500,000 OCR operations
    • 4,000,000 Recognise text operations

    Your total bill will be constructed as follows:

    Operations Resource Calculations Subtotal
    1,500,000 Tag and 1,500,000 Face operations: S1 transactions First 1,000,000 transactions: $-/1000 * 1,000,000 = $-
    Remaining 2,000,000 transactions: $-/1000 * 2,000,000 = $-
    500,000 OCR operations: S2 transactions $-/1000 * 500,000 = $- $-
    1,500,000 Describe and 4,000,000 Recognise Text operations: S3 transactions $-/1000 * 5,500,000 = $- $-
    Total $- $-
