however, I don't understand how I do using the generic endpoint to meet the requirement, "You need to use contoso1 to make a different size of a product photo". I'm not so sure to use the generic endpoint.

Clarified. If you go on the API documentation https://westus.dev.cognitive.microsoft.com/docs/services/computer-vision-v3-2/operations/56f91f2e778daf14a499f20c/console (here is the version 3.2 but it's the same) you can verify that both type of endpoint are supported. If you choose a custom endpoint named contos1 you'll get the following url request: https://westus.dev.cognitive.microsoft.com/docs/services/computer-vision-v3-2/operations/56f91f2e778daf14a499f20c/console. So correct answers are https://contoso1.cognitiveservices.azure.com/ generateThumbnail

sorry i pasted twice the same url in the message before: with the custom endpoint the url of the service is: https://contoso1.cognitiveservices.azure.com/vision/v3.2/generateThumbnail?width=300&height=200&smartCropping=true&model-version=latest

Both answers are incorrect. The correct answers are: https://contoso1.cognitiveservices.azure.com/ AND generateThumbnail westus.dev.cognitive.microsoft.com wouldn't be a correct Computer Vision endpoint if the resource name is contoso1. Also, per the documentation, areaOfInterest "returns a bounding box around the most important area of the image", it doesn't return a different size photo (https://docs.microsoft.com/en-us/rest/api/computervision/3.1/get-area-of-interest).

I agree with generateThumbnail, however first answer provided by ET should be correct https://westus.api.cognitive.microsoft.com as shown in https://docs.microsoft.com/en-us/rest/api/computervision/3.1/generate-thumbnail/generate-thumbnail?tabs=HTTP#examples

contoso1 is a Computer Vision resource, so you would not specify /vision in the URL. Therefore I think the correct answer must be westus.api.cognitive.microsoft.com

I agree with both answers here. The example https://westus.api.cognitive.microsoft.com is just an example and it needs to be changed to use the source in real which is contoso1.

Today (july 2023), both regional and resource endpoints are supported. So both are correct : https://contoso1.cognitiveservices.azure.com/ AND https://westus.api.cognitive.microsoft.com Doc : https://learn.microsoft.com/en-us/azure/ai-services/cognitive-services-custom-subdomains#what-if-an-sdk-asks-me-for-the-region-for-a-resource "Regional endpoints and custom subdomain names are both supported and can be used interchangeably." I tested it by creating a custom vision resource and used it with both endpoints.

1. https://contoso1.cognitiveservices.azure.com 2. generateThumbnail https://learn.microsoft.com/en-us/azure/cognitive-services/computer-vision/concept-generating-thumbnails A thumbnail is a reduced-size representation of an image. Thumbnails are used to represent images and other data in a more economical, layout-friendly way. The Computer Vision API uses smart cropping to create intuitive image thumbnails that include the most important regions of an image with priority given to any detected faces. The Computer Vision thumbnail generation algorithm works as follows: - Remove distracting elements from the image and identify the area of interest—the area of the image in which the main object(s) appears. - Crop the image based on the identified area of interest. - Change the aspect ratio to fit the target thumbnail dimensions.

https://contoso1.cognitiveservices.azure.com/ is correct. Context from ChatGPT: westus.api.cognitive.microsoft.com is also a valid endpoint for the Cognitive Services APIs, including the Computer Vision API. However, it is important to note that this endpoint is deprecated and will be retired on October 31, 2024. Therefore, it is recommended to use the newer endpoint format https://<resource-name>.cognitiveservices.azure.com/ for any new development work. This endpoint format follows a more standard Azure resource URL pattern and is also more flexible in terms of geographic distribution and availability. Hope it helps.
