API Requests will soon Require Authentication

Starting October 1, 2026, the Rösti API will require all requests to include a valid API key. Requests without a key will no longer be accepted.

If you are currently making unauthenticated requests, obtain a free API key by following following this guide.

If you see a X-Api-Key-Warning header in the API response, it indicates that your request either did not include a key or the key provided is invalid.
