Analyzing with the API

You can use the Document Understanding API to analyze documents.

For information about using the API and signing requests, see REST APIs and Security Credentials. For information about SDKs, see Software Development Kits and Command Line Interface.

The APIs apply to both pretrained and custom models. To use them with a custom model, the modelId field is used to specify a custom model ID in the feature details. If no custom model ID is specified, the pretrained model is used.
