    ## Overview


    The OnetSolutions API provides programmatic access to manage your cloud
    infrastructure, domains, and web hosting services.


    ## Authentication


    All API requests require authentication using one of the following methods:


    - **JWT Token**: Obtain a token via login endpoints and include it in the
    `Authorization: Bearer <token>` header

    - **API Key**: Generate an API key from your account settings and use it as
    `Authorization: Bearer sk-onetsolutions-...`


    ## Rate Limiting


    API requests are rate-limited to ensure fair usage:

    - **Standard**: 1000 requests per minute

    - **Burst**: 100 requests per second


    ## Pagination


    List endpoints return paginated results. Use `page` and `page_size` query
    parameters.


    ## Error Handling


    The API uses standard HTTP status codes:

    - `200` Success

    - `201` Created

    - `400` Bad Request

    - `401` Unauthorized

    - `403` Forbidden

    - `404` Not Found

    - `429` Too Many Requests
