    Welcome to the reference for the Lichess API! Lichess is free/libre,

    ## Endpoint

    All requests go to `https://lichess.org` (unless otherwise specified).


    ## Clients

    - [Python general API](https://github.com/lichess-org/berserk)

    - [MicroPython general API](https://github.com/mkomon/uberserk)

    - [Python general API - async](https://pypi.org/project/async-lichess-sdk)

    - [.NET general API](https://github.com/Dblike/LichessSharp)


    ## Rate limiting

    All requests are rate limited using various strategies,

    to ensure the API remains responsive for everyone.

    Only make one request at a time.

    If you receive an HTTP response with a [429 status](https://en.wikipedia.org/wiki/List_of_HTTP_status_codes#429),

    you have exceded one of the rate limits.

    In most cases, waiting one minute before retrying will be sufficient, but some limits may require longer.

    Reduce your request frequency before retrying.


    ## Streaming with ND-JSON

    Some API endpoints stream their responses as [Newline Delimited JSON a.k.a. **nd-json**](https://github.com/ndjson/ndjson-spec), with one JSON object per line.


    Here''s a [JavaScript utility function](https://gist.github.com/ornicar/a097406810939cf7be1df8ea30e94f3e) to help reading NDJSON streamed responses.


    ## Authentication

    ### Which authentication method is right for me?

    [Read about the Lichess API authentication methods and code examples](https://github.com/lichess-org/api/blob/master/example/README.md)


    ### Personal Access Token

    Personal API access tokens allow you to quickly interact with Lichess API without going through an OAuth flow.

    - [Generate a personal access token](https://lichess.org/account/oauth/token)

    - `curl https://lichess.org/api/account -H "Authorization: Bearer {token}"`

    - [NodeJS example](https://github.com/lichess-org/api/tree/master/example/oauth-personal-token)


    ### Token Security

    - Keep your tokens secret. Do not share them in public repositories or public forums.

    - Your tokens can be used to make your account perform arbitrary actions (within the limits of the tokens'' scope). You remain responsible for all activities on your account.

    - Do not hardcode tokens in your application''s code. Use environment variables or a secure storage and ensure they are not shipped/exposed to users. Be especially careful that they are not included in frontend bundles or apps that are shipped to users.

    - If you suspect a token has been compromised, revoke it immediately.


    To see your active tokens or revoke them, see [your Personal API access tokens](https://lichess.org/account/oauth/token).


    ### Authorization Code Flow with PKCE

    The authorization code flow with PKCE allows your users to **login with Lichess**.

    Lichess supports unregistered and public clients (no client authentication, choose any unique client id).

    The only accepted code challenge method is `S256`.

    Access tokens are long-lived (expect one year), unless they are revoked.

    Refresh tokens are not supported.


    See the [documentation for the OAuth endpoints](#tag/OAuth) or

    the [PKCE RFC](https://datatracker.ietf.org/doc/html/rfc7636#section-4) for a precise protocol description.

    #### Real life examples

    - [PyChess](https://github.com/gbtami/pychess-variants) ([source code](https://github.com/gbtami/pychess-variants))

    - [Lichess4545](https://www.lichess4545.com/) ([source code](https://github.com/cyanfish/heltour))

    - [English Chess Federation](https://ecf.octoknight.com/)

    - [Rotherham Online Chess](https://rotherhamonlinechess.azurewebsites.net/tournaments)


    ### Token format

    Access tokens and authorization codes match `^[A-Za-z0-9_]+$`.

    The length of tokens can be increased without notice. Make sure your application can handle at least 512 characters.

    By convention tokens have a recognizable prefix, but do not rely on this.

        An empty line is sent every 7 seconds for keep alive purposes.


        Each non-empty line is a JSON object containing a `type` field. Possible values are:

        - `gameStart` Start of a game

        - `gameFinish` Completion of a game

        - `challenge` A player sends you a challenge or you challenge someone

        - `challengeCanceled` A player cancels their challenge to you

        - `challengeDeclined` The opponent declines your challenge


        When the stream opens, all current challenges and games are sent.


        Only one global event stream can be active at a time. When the stream opens, the previous one with the same access token is closed.

      description: 'Create a public seek, to start a game with a random player.


        ### Real-time seek


        Specify the `time` and `increment` clock values.

        The response is streamed but doesn''t contain any information.


        **Keep the connection open to keep the seek active**.


        If the client closes the connection, the seek is canceled. This way, if the client terminates, the user won''t be paired in a game they wouldn''t play.

        When the seek is accepted, or expires, the server closes the connection.


        **Make sure to also have an [Event stream](#tag/board/GET/api/board/game/stream/{gameId}) open**, to be notified when a game starts.

        We recommend opening the [Event stream](#tag/board/GET/api/board/game/stream/{gameId}) first, then the seek stream. This way,

        you won''t miss the game event if the seek is accepted immediately.


        ### Correspondence seek


        Specify the `days` per turn value.

        The response is not streamed, it immediately completes with the seek ID. The seek remains active on the server until it is joined by someone.
