        Create a new API wrapper instance based on the given `client_secret` and `client_id`. If you
        give a `client_id` and it is not a file, you must also give a secret. If you specify an
        `access_token` then you don't need to specify a `client_id`. It is allowed to specify
        neither - in this case, you will be restricted to only using endpoints that do not
        require authentication.  If a file is given as `client_id`, client ID, secret and 
        base url are read from that file.

        You can also specify an `access_token`, directly or as a file (as written by `log_in()`_). If
        a file is given, Mastodon.py also tries to load the base URL from this file, if present. A
        client id and secret are not required in this case.

        Mastodon.py can try to respect rate limits in several ways, controlled by `ratelimit_method`.
        "throw" makes functions throw a `MastodonRatelimitError` when the rate
        limit is hit. "wait" mode will, once the limit is hit, wait and retry the request as soon
        as the rate limit resets, until it succeeds. "pace" works like throw, but tries to wait in
        between calls so that the limit is generally not hit (How hard it tries to not hit the rate
        limit can be controlled by ratelimit_pacefactor). The default setting is "wait". Note that
        even in "wait" and "pace" mode, requests can still fail due to network or other problems! Also
        note that "pace" and "wait" are NOT thread safe.

        Specify `api_base_url` if you wish to talk to an instance other than the flagship one. When
        reading from client id or access token files as written by Mastodon.py 1.5.0 or larger,
        this can be omitted.

        By default, a timeout of 300 seconds is used for all requests. If you wish to change this,
        pass the desired timeout (in seconds) as `request_timeout`.

        For fine-tuned control over the requests object use `session` with a requests.Session.
                
        The `mastodon_version` parameter can be used to specify the version of Mastodon that Mastodon.py will
        expect to be installed on the server. The function will throw an error if an unparseable 
        Version is specified. If no version is specified, Mastodon.py will set `mastodon_version` to the 
        detected version.
        
        The version check mode can be set to "created" (the default behaviour), "changed" or "none". If set to 
        "created", Mastodon.py will throw an error if the version of Mastodon it is connected to is too old
        to have an endpoint. If it is set to "changed", it will throw an error if the endpoints behaviour has
        changed after the version of Mastodon that is connected has been released. If it is set to "none",
        version checking is disabled.
        
        `feature_set` can be used to enable behaviour specific to non-mainline Mastodon API implementations.
        Details are documented in the functions that provide such functionality. Currently supported feature
        sets are `mainline`, `fedibird` and `pleroma`.

        Post a status. Can optionally be in reply to another status and contain
        media.
        
        `media_ids` should be a list. (If it's not, the function will turn it
        into one.) It can contain up to four pieces of media (uploaded via 
        `media_post()`_). `media_ids` can also be the `media dicts`_ returned 
        by `media_post()`_ - they are unpacked automatically.

        The `sensitive` boolean decides whether or not media attached to the post
        should be marked as sensitive, which hides it by default on the Mastodon
        web front-end.

        The visibility parameter is a string value and accepts any of:
        'direct' - post will be visible only to mentioned users
        'private' - post will be visible only to followers
        'unlisted' - post will be public but not appear on the public timeline
        'public' - post will be public

        If not passed in, visibility defaults to match the current account's
        default-privacy setting (starting with Mastodon version 1.6) or its
        locked setting - private if the account is locked, public otherwise
        (for Mastodon versions lower than 1.6).

        The `spoiler_text` parameter is a string to be shown as a warning before
        the text of the status.  If no text is passed in, no warning will be
        displayed.

        Specify `language` to override automatic language detection. The parameter
        accepts all valid ISO 639-2 language codes.

        You can set `idempotency_key` to a value to uniquely identify an attempt
        at posting a status. Even if you call this function more than once,
        if you call it with the same `idempotency_key`, only one status will
        be created.

        Pass a datetime as `scheduled_at` to schedule the toot for a specific time
        (the time must be at least 5 minutes into the future). If this is passed,
        status_post returns a `scheduled toot dict`_ instead.

        Pass `poll` to attach a poll to the status. An appropriate object can be
        constructed using `make_poll()`_ . Note that as of Mastodon version
        2.8.2, you can only have either media or a poll attached, not both at 
        the same time.

        **Specific to `pleroma` feature set:**: Specify `content_type` to set 
        the content type of your post on Pleroma. It accepts 'text/plain' (default), 
        'text/markdown', 'text/html' and 'text/bbcode. This parameter is not 
        supported on Mastodon servers, but will be safely ignored if set.

        **Specific to `fedibird` feature set:**: The `quote_id` parameter is 
        a non-standard extension that specifies the id of a quoted status.

        Returns a `toot dict`_ with the new status.
