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 here.

If you get back a 401 with missing API key, please set the 'X-API-Key' header or invalid API key it indicates that your request either did not include a key or the key provided is invalid.
