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, please wait a full minute before resuming API usage.
Some API endpoints stream their responses as Newline Delimited JSON a.k.a. nd-json, with one JSON object per line.
Here's a JavaScript utility function to help reading NDJSON streamed responses.
Read about the Lichess API authentication methods and code examples
Personal API access tokens allow you to quickly interact with Lichess API without going through an OAuth flow.
- Generate a personal access token
curl https://lichess.org/api/account -H \"Authorization: Bearer {token}\"
- NodeJS example
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 or the PKCE RFC for a precise protocol description.
- Demo app
- Minimal client-side example
- Flask/Python example
- Java example
- NodeJS Passport strategy to login with Lichess OAuth2
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.
