Rossum

Rossum is an AI-powered document processing platform specialised in transactional documents — invoices, purchase orders, contracts — with cognitive data capture, validation workflows and integration extensions.

Rossum publishes 5 APIs on the APIs.io network, including Annotations API, Authentication API, Queues API, and 2 more. Tagged areas include AI, Document AI, IDP, Invoices, and OCR.

Rossum’s developer surface includes authentication, engineering blog, documentation, pricing, GitHub presence, and 9 more developer resources.
