## Data

- Freshness: 24 hours
- Countries: Belgium
- Keep data: no limit
- Use data: Use the API for your own product or internal work, within your plan. You may not bypass the limits, overload the service, impersonate the KBO or the National Bank, or republish the data as a competing API. Caching responses for your own users is allowed. [...] The API is for your own product or your own internal work, not for reselling requests or information. You may not share your key, sub-license it or let third parties use it, and you may not offer API responses as a service, a database or an extract to parties outside your own organisation. Showing the data to your own users inside your own product is allowed: that is what the API is for. Querying systematically in order to rebuild a copy of the register or of the annual accounts is not.
