  description: >-
    The Backblaze B2 Native API provides programmatic access to Backblaze B2 Cloud Storage.
    It covers account authorization, bucket management, file upload and download, lifecycle
    rules, application key management, large file handling, replication, and event notifications.
    The API uses HTTPS with JSON request and response bodies. Authentication is performed via
    the b2_authorize_account endpoint which returns an authorization token used for subsequent calls.
