Changelog
Changes to the API itself. For changes in the Belgian nomenclature data, see data changes.
2026-09-26. Keys move to the dashboard
- Registration creates the account and signs you in. Keys are created from the dashboard, where the secret is shown once next to the list it belongs in.
- The dashboard says plainly whether a plan is active, because a key without one answers 402 on every request.
- OpenAPI description at /openapi.json, with an interactive reference at /docs on the API host.
2026-09-21. First release
- Codes, descriptions, classification, tariffs, search and source status over /v1.
- Point-in-time queries with ?at= on codes, descriptions and tariffs.
- Changes API with before and after values and effective dates, derived from the source's own validity windows rather than from when we started collecting.
- /v1/changes/summary and /v1/changes/months for counts over a period.
- Public code lookup and monthly change pages, no account required.
- Accounts, API keys and subscription billing.
