lichess 0.1.6

Python Lichess API

lichess: a Python wrapper for the Lichess API

lichess is a Python library for interacting with the Lichess API and can be used to get profile data, game data, and much more.

This project is still in Pre-Alpha. As a result, it is still unstable and not all features have been implemented.

Click here for the full documentation for this package.

Install

You can install lichess on the Terminal (macOS/UNIX) or the Command Prompt (Windows) with:

pip install lichess

Alternatively, you can use Git to clone the repository from GitHub with:

git clone https://github.com/qe/lichess.git
cd lichess
pip install .

Or, if you already have it, upgrade to the latest version with:

pip install lichess --upgrade

Example

For the full documentation, please check the Lichess Python API Documentation.

Some methods, such as Client.get_email(), require authorization while others, such as Client.get_leaderboard(), do not require it. As a result, if you want to use a method/endpoint that does require authorization, you will need to generate a personal access token on Lichess. If you do so, this will be your API Key.

To determine whether or nor you need to generate a personal access token, check if the endpoint you are interested in using has a OAuth2 badge in the Lichess API Documentation.

Here is an example of using lichess with a personal access token:

import lichess

API_KEY = "<YOUR API KEY GOES HERE>"
myclient = lichess.Client(token=API_KEY)

print(myclient.get_email())

{'email': '[e-mail]'}

Here is an example of using lichess without a personal access token:

import lichess

myclient = lichess.Client()

print(myclient.get_data("ismodes"))

~ json.decoder.JSONDecodeError: Expecting value: line 1 column 2 (char 1) happens when browser prompts actual file download

High likelihood this error relates with NDJSONs

Warnings

Make sure your inputs are valid.

There is basic error handling for some invalid inputs, but there are exceptions.

Firstly, there are many types of invalid inputs. Here is an example:

• Usernames that don’t exist

  • Valid username, but no user has taken it

  • Invalid username

lichess does basic error handling with invalid inputs (using Regex), but it does not account for valid inputs that do not exist. Here is a more explicit example:

"jzq0wUnCYR" is a valid username (i.e. it can be registered), but at the time of writing this, there is no user by this name. As a result, the following code does not return everything:

import lichess

myclient = lichess.Client()

print(myclient.get_status("jzq0wUnCYR", "penguingim1"))

[{'name': 'penguingim1', 'title': 'GM', 'patron': True, 'id': 'penguingim1'}]

Conversely, "jzq0 wUnCYR" is an invalid username, since it has invalid characters (note the whitespace!) However, lichess does catch this error, as seen below:

import lichess

myclient = lichess.Client()

print(myclient.get_status("jzq0 wUnCYR", "penguingim1"))

Traceback (most recent call last):
  File "main.py", line 109, in <module>
    main()
  File "main.py", line 76, in main
    print(myclient.get_status("jzq0 wUnCYR", "penguingim1"))
  raise ArgumentValueError("One or more usernames are invalid.")
lichess.exceptions.ArgumentValueError: One or more usernames are invalid.

It is your responsibility to make sure your inputs are valid, but lichess tries its best to catch errors <3
