Access & authentication

Plan

One plan — €49/month. Covers all data endpoints and official CSV exports. No free tier, trial, or usage billing. See pricing →

API key

Subscribe, then generate a personal key from your account. Registration alone does not grant access.

Authentication

Send the key on every request as an Authorization: Bearer <key> header (or x-api-key). Never in a URL. A browser GET without a key returns 401.

Rate limit

120 requests/minute per key. Responses are JSON and CORS-enabled.

CSV exports

Official CSV exports of the same datasets are included with the subscription (server-authorized, session-based).

Discovery

The discovery root /api/v1 and the OpenAPI spec are the only keyless endpoints.

See the response shape (no key needed)

Static examples, not live API access. These are canned example responses so you can see the JSON shape before subscribing. Values are placeholders, not live data. The live /api/v1 data endpoints require an active €49/month subscription and a personal API key.
