Lichess.org API reference

Jentic publishes the only available OpenAPI specification for Lichess.org API reference, keeping it validated and agent-ready. The Lichess API exposes the free, open-source chess platform's full feature set including account management, game streaming, puzzle workflows, broadcasts, tournaments, bot play, and analysis. Agents can stream live game events, fetch player rating histories, query the opening explorer and tablebase, run puzzle dashboards, and operate Lichess bots. The API is OAuth2-protected with personal access tokens and supports newline-delimited JSON streaming for board events and TV feeds.

Connect Your Agent

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Flichess.org" | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Flichess.org" | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
