  description: >-
    The Monta Public API lets developers connect to the Monta EV-charging
    platform to read charge points, start and stop charges (charging
    sessions), inspect EVSE availability and pricing, and read wallet
    transactions. Authentication uses OAuth2 client-credentials: exchange a
    clientId and clientSecret for a short-lived bearer access token (and a
    longer-lived refresh token) and send it as a Bearer token on each request.
