API Usage Examples

Note

These examples are written in Python version 3.6.3 and use requests version 2.18.4.

Prerequisites

All the examples assume you have a development version of the ListenBrainz server set up on localhost. Remember to set DEBUG to True in the config. When in production, you can replace localhost with api.listenbrainz.org to use the real API. In order to use either one, you’ll need a token. You can find it under ROOT/profile/ when signed in, with ROOT being either localhost for the dev version or listenbrainz.org for the real API.

Caution

You should use the token from the API you’re using. In production, change the token to one from listenbrainz.org.

Examples

Submitting Listens

See JSON Documentation for details on the format of the Track dictionaries.

If everything goes well, the json response should be {“status”: “ok”}, and you should see a recent listen of “Never Gonna Give You Up” when you visit ROOT/user/{your-user-name}.

from time import time
import requests

ROOT = '127.0.0.1'

def submit_listen(listen_type, payload, token):
    """Submits listens for the track(s) in payload.

    Args:
        listen_type (str): either of 'single', 'import' or 'playing_now'
        payload: A list of Track dictionaries.
        token: the auth token of the user you're submitting listens for

    Returns:
         The json response if there's an OK status.

    Raises:
         An HTTPError if there's a failure.
         A ValueError is the JSON in the response is invalid.
    """

    response = requests.post(
        url="http://{0}/1/submit-listens".format(ROOT),
        json={
            "listen_type": listen_type,
            "payload": payload,
        },
        headers={
            "Authorization": "Token {0}".format(token)
        }
    )

    response.raise_for_status()

    return response.json()

    EXAMPLE_PAYLOAD = [

    # Input token from the user and call submit listen
    token = input('Please enter your auth token: ')
    json_response = submit_listen(listen_type='single', payload=EXAMPLE_PAYLOAD, token=token)

    print("Response was: {0}".format(json_response))
    print("Check your listens - there should be a Never Gonna Give You Up track, played recently.")

Getting Listen History

See JSON Documentation for details on the format of the Track dictionaries.

If there’s nothing in the listen history of your user, you can run submit_listens before this.

If there is some listen history, you should see a list of tracks like this:

import requests

ROOT = '127.0.0.1'
# The following token must be valid, but it doesn't have to be the token of the user you're
# trying to get the listen history of.
TOKEN = 'YOUR_TOKEN_HERE'
AUTH_HEADER = {
    "Authorization": "Token {0}".format(TOKEN)
}


def get_listens(username, min_ts=None, max_ts=None, count=None):
    """Gets the listen history of a given user.

    Args:
        username: User to get listen history of.
        min_ts: History before this timestamp will not be returned.
                DO NOT USE WITH max_ts.
        max_ts: History after this timestamp will not be returned.
                DO NOT USE WITH min_ts.
        count: How many listens to return. If not specified,
               uses a default from the server.

    Returns:
        A list of listen info dictionaries if there's an OK status.

    Raises:
        An HTTPError if there's a failure.
        A ValueError if the JSON in the response is invalid.
        An IndexError if the JSON is not structured as expected.
    """
    response = requests.get(
        url="http://{0}/1/user/{1}/listens".format(ROOT, username),
        params={
            "min_ts": min_ts,
            "max_ts": max_ts,
            "count": count,
        },
        # Note that an authorization header isn't compulsary for requests to get listens
        # BUT requests with authorization headers are given relaxed rate limits by ListenBrainz
        headers=AUTH_HEADER,
    )

    response.raise_for_status()

    return response.json()['payload']['listens']

if __name__ == "__main__":
    username = input('Please input the MusicBrainz ID of the user: ')
    listens = get_listens(username)

    for track in listens:
        print("Track: {0}, listened at {1}".format(track["track_metadata"]["track_name"],
                                                   track["listened_at"]))

Track: Never Gonna Give You Up, listened at 1512040365
Track: Never Gonna Give You Up, listened at 1511977429

Latest Import

Set and get the timestamp of the latest import into ListenBrainz.

Setting

from time import time
import requests

ROOT = '127.0.0.1'

def set_latest_import(timestamp, token):
    """Sets the time of the latest import.

    Args:
        timestamp: Unix epoch to set latest import to.
        token: the auth token of the user you're setting latest_import of

    Returns:
        The JSON response if there's an OK status.

    Raises:
        An HTTPError if there's a failure.
        A ValueError if the JSON response is invalid.
    """
    response = requests.post(
        url="http://{0}/1/latest-import".format(ROOT),
        json={
            "ts": timestamp
        },
        headers={
            "Authorization": "Token {0}".format(token),
        }
    )

    response.raise_for_status()

    return response.json()

if __name__ == "__main__":
    ts = int(time())
    token = input('Please enter your auth token: ')
    json_response = set_latest_import(ts, token)

    print("Response was: {0}".format(json_response))
    print("Set latest import time to {0}.".format(ts))

Getting

If your user has never imported before and the latest import has never been set by a script, then the server will return 0 by default. Run set_latest_import before this if you don’t want to actually import any data.

import requests

ROOT = '127.0.0.1'
# The token can be any valid token.
TOKEN = 'YOUR_TOKEN_HERE'
AUTH_HEADER = {
    "Authorization": "Token {0}".format(TOKEN)
}

def get_latest_import(username):
    """Gets the latest import timestamp of a given user.

    Args:
        username: User to get latest import time of.

    Returns:
        A Unix timestamp if there's an OK status.

    Raises:
        An HTTPError if there's a failure.
        A ValueError if the JSON in the response is invalid.
        An IndexError if the JSON is not structured as expected.
    """
    response = requests.get(
        url="http://{0}/1/latest-import".format(ROOT),
        params={
            "user_name": username,
        },
        headers=AUTH_HEADER,
    )

    response.raise_for_status()
    return response.json()["latest_import"]


if __name__ == "__main__":
    username = input('Please input the MusicBrainz ID of the user: ')
    timestamp = get_latest_import(username)

    print("User {0} last imported on {1}".format(username, timestamp))

You should see output like this:
