Welcome to the Jaarrekening.be developer documentation
This documentation helps you interact with our API to access financial, legal, and structural data about all Belgian enterprises. You’ll find endpoints for enterprise profiles, annual reports, directors, ratios, and investments — all powered by official sources.
Everything starts with an API token. You’ll need this to authenticate with our endpoints.
Sign in and create a personal or team API token to start making requests.
Browse available endpoints, try them out, and see example responses live.
Our API is documented with the OpenAPI 3.1 spec, fully integrated with Mintlify’s API playground.
Learn how to use Bearer tokens securely in every request.
Query thousands of enterprises with filters and pagination.
Get director and investment data via structured annual reports.
Understand solvability, EBITDA, and other financial indicators.
We’re here to help.
