Public Endpoints

Depending on your license which is verified based on your API key, there are two types of limitations available for each ML Package:

Community licensed traffic - The size of documents that can be extracted is limited to 2 pages and 4MB and there is a rate-limiting per account at 50 requests per hour. When an account reaches the rate limit, the server responds with 429 - Too Many Requests error status. Community Edition license of Document Understanding^TM has no quantity displayed on the Licenses page within the Document Understanding section.
Enterprise licensed traffic - The consumption entitlement is displayed as a number of pages on the Licenses page within the Document Understanding section. The size of documents that can be extracted is limited per page to 20 megapixels and 10MB, in JSON-Base64 format.

Note:

Public extraction endpoints (endpoints containing /ie, for example Invoices, https://du.uipath.com/ie/invoices) only work with documents that have up to 30 pages (or 30MB payload in total).

Make sure you connect your activity to the correct endpoint according to each server region.

Important:

Having an Enterprise licensing plan on your Automation Cloud does not imply that you have access to the Enterprise licensed traffic for Document Understanding. Access to the Enterprise licensed traffic is subject to a different, separate license.
