Rossum (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. The Rossum REST API is exposed across two deployment domains: the legacy elis.rossum.ai and per-tenant rossum.app.

APIs.json: apis.yml

APIs

• REST v1 (legacy) — https://api.elis.rossum.ai/v1 — organizations, users, workspaces, queues, schemas, documents, annotations, hooks. Token auth (~162h tokens). Docs.
• Tenant API (newer) — https://<tenant>.rossum.app/api/v1 — same surface, served from each customer's tenant subdomain.

OpenAPI

Rossum publishes interactive API documentation but does not host a downloadable OpenAPI/Swagger document at a public anonymous URL as of 2026-05-08; pipeline did not retrieve a spec into openapi/. Python SDK and CLI are open source under github.com/rossumai.
