Authentication
Every request except/health needs Authorization: Bearer <KEY> (or ?api_key=<KEY>). A missing or wrong key answers 401.
Regions
Choose the region when you call the API: the two regions have the same paths, fields and answers, and your data stays on the server of the region you call. Examples use the Europe address. Every REST endpoint has a page under API Reference where you can pick the region, send a request and see the answer.
