Lichess API

healthy 4,396 Subscribers

Lichess as an API — the open-source chess platform, returned as clean JSON, no key. Look up any player's profile (titles, ratings across bullet, blitz, rapid and classical, game counts, country, FIDE rating), their rating history per variant and online status; pull the top players for any performance type; fetch a user's recent games with openings, clocks, results and full move lists; get a Stockfish cloud evaluation of any position by FEN (best lines, centipawn or mate scores); serve the daily puzzle or any puzzle by id (with solution and themes); and list current, upcoming and finished tournaments. Live data straight from lichess.org. Distinct from Chess.com player stats: Lichess is its own platform with cloud engine analysis, a puzzle database and arena tournaments — ideal for chess apps, coaching tools, analysis boards, bots and leaderboards. 9 data endpoints. Authenticated with an x-oanor-key; fair-use rate limits per plan.

Chess Puzzles API — oanor API marketplace

Chess Puzzles API

Serve chess tactics puzzles on demand: a random puzzle (optionally constrained by theme and rating), a single puzzle by id, full search and filtering by tactic theme and difficulty rating, and the complete list of available themes. Every puzzle includes the starting position as FEN, the full solution as UCI moves, the side to move, the difficulty rating, popularity and play count, theme and opening tags and a direct link to train it on Lichess. Built on a curated 20,000-puzzle sample of the open Lichess puzzle database (CC0) spanning 73 themes and ratings from roughly 400 to 3100. Every endpoint accepts input via the query string or the request body and returns lean JSON. Pure server-side data (no third-party upstream), so responses are instant and always available. Ideal for chess apps, training tools, "puzzle of the day" features and games.

 Chess Openings API — oanor API marketplace

Chess Openings API

The Encyclopaedia of Chess Openings (ECO) as an API — 3,161 named chess openings and variations with their ECO code (A00–E99), full name, family/variation and the exact move sequence (PGN and a clean move list). Search openings by name, ECO code or ECO volume; list every opening under a code (e.g. B20 → 27 Sicilian lines); pick a random opening; and — the killer feature — identify which opening a game is in from a sequence of moves (e.g. "1. e4 c5 2. Nf3" → Sicilian Defense). Ideal for chess apps, game analysis, training tools, bots and trivia. Open data from the lichess-org/chess-openings project.
