Microsoft Azure AI Engineer Associate AI-102 Practice Question
You have published a Custom Vision image-classification model to an Azure AI Vision prediction resource. You will call the hosted REST endpoint from a single-page web application and you already know the project ID, the published iteration name, and the endpoint URL.
Which HTTP header must be included in every prediction request so that the service authorizes the call?
The hosted prediction endpoint does not accept Azure AD bearer tokens or training keys. Instead, each request must include the key that was generated when the prediction resource was created. That key is passed in an HTTP header named "Prediction-Key". Requests that omit this header-or that provide any other header such as "Training-Key" or "Ocp-Apim-Subscription-Key"-are rejected with an authorization error.
