Persium M2M API

The Persium machine-to-machine (M2M) API lets customer backends fetch stations, sensors, and measurement data for their organisation.

Authentication uses standard OAuth 2.0 Client Credentials against Persium's Keycloak. All endpoints are read-only and hard-scoped to the calling organisation — query-string organisation overrides are ignored.
