Frequently asked questions

How do I get an API key?

Create a free account and go to Settings, API. There you create a token that you send as a Bearer token in the Authorization header.

How many requests do I get?

Free: 10 a month. Starter: 500. Pro: 2,500. Once the allowance is used, bought packages are spent; without one you get a 429 response with the date the allowance starts again.

What counts as a request?

Every call that gets an answer, even when the company does not exist. If something fails on our side (a 5xx error), the request does not count.

What language are the responses in?

Add ?lang=nl, fr or en, or send an Accept-Language header. Codes such as legal forms and statuses then come back in that language.

Where is the documentation?

At docs.jaarrekening.be, with a quickstart and the reference for every endpoint.
