API to get the Add-on Capability supported by a prebuilt model

Hi Bijaya Rai,

At this time, Azure Document Intelligence does not provide a dedicated API that directly lists the add-on capabilities supported by a specific prebuilt model or indicates which of these capabilities may incur additional charges. While the service includes APIs to list and retrieve metadata for document models (such as model ID, description, and version), it does not return detailed information about optional features like Query Fields, classification, barcode extraction, or signature detection.

You can use the List Models API (GET /documentintelligence/documentModels) to retrieve all available models in your resource. This API helps identify accessible models but does not expose their supported analysis features or add-ons. For details on what each prebuilt model supports—such as fields extracted or advanced capabilities—you can refer to the official model overview documentation.

Some capabilities, like Query Fields, can be enabled using request parameters (e.g., features=queryFields) during document analysis. These are considered premium features and may incur additional costs. For a breakdown of features and associated pricing, we recommend reviewing the Azure Document Intelligence pricing page.

I hope this information helps. Thank you!
