  description: >-
    REST API for the eSIM Go connectivity and travel-data platform. Resellers and
    brands use it to browse the data-bundle catalogue, place and track orders, assign
    bundles to eSIMs, retrieve install/QR provisioning details, manage inventory,
    look up network coverage, and receive usage callbacks. Authentication is via the
    X-API-Key header.
