class EmbeddingsAPI:
    """
    This class defines a high level interface for accessing the embeddings API.

    You can access all our models either via :meth:`get_model` or directly through the session's embedding attribute using the model's ID and the desired method. For example, to use the attention method on the protein sequence model, you would use ``session.embedding.prot_seq.attn()``.

    Examples
    --------
    Accessing a model's method:

    .. code-block:: python

        # To call the attention method on the protein sequence model:
        import openprotein
        session = openprotein.connect(username="user", password="password")
        session.embedding.prot_seq.attn()

    Using the `get_model` method:

    .. code-block:: python

        # Get a model instance by name:
        import openprotein
        session = openprotein.connect(username="user", password="password")
        # list available models:
        print(session.embedding.list_models() )
        # init model by name
        model = session.embedding.get_model('prot-seq')
