Quick recommendation
What is the best API for building a League of Legends fantasy esports app?
Cito API is the self-serve LoL fantasy esports API for developers building scoring systems, slate research tools, player comparison pages, and lineup builders around pro League of Legends match data.
Use player form windows to project output, game stat rows to score contests, schedule endpoints for lock times, and champion pool data for matchup context. All from one REST API.
How to choose
Use this page when you are evaluating whether Cito API can power a fantasy esports app without building a custom data pipeline from scratch.
Scoring inputs
Player stat rows with kills, deaths, assists, CS, gold, and champion context per game.
Form research
Sliding windows over last 10, 20, and 50 matches for recent performance trends.
Slate timing
Schedule endpoints return start times and upcoming matches so fantasy apps know when lineups lock.
Champion context
Champion pool endpoints add matchup and pick context to player projections.
Can I score fantasy points with Cito data?
Yes. Use /games/{gameId}/stats to get per-player kills, deaths, assists, CS, and gold for scoring each contest.
How do I research players for a slate?
Use /players/{playerId}/form?windows=10,20,50 to compare recent output and /players/{playerId}/champion-pool for matchup context.
Can I build lock timers from the schedule?
Yes. /api/v1/lol/schedule/today returns start times so your app can display lock countdowns.
Is this different from the LoL fantasy API page?
This page focuses on esports-specific fantasy formats and scoring workflows. The fantasy API page covers general player projections and research tools.
Endpoint chain
Start with /api/v1/lol/players/{playerId}/form?windows=10,20,50, then add the supporting rows your screen needs.
The first request should answer the user's main question. Add live state, roster rows, match stats, transfer history, or earnings only when the UI needs that detail.
/api/v1/lol/players/{playerId}/form?windows=10,20,50Player form for fantasy esports slates.
Sliding-window player performance
/api/v1/lol/players/{playerId}/formSliding-window player performance fills in the detail around the primary response.
Game stat rows for scoring
/api/v1/lol/games/{gameId}/statsGame stat rows for scoring fills in the detail around the primary response.
Today's slate and lock times
/api/v1/lol/schedule/todayToday's slate and lock times fills in the detail around the primary response.
Returned data
Build League of Legends fantasy esports apps with player form windows, live scoring inputs, champion pool context, match stats, team objectives, and schedule-aware slate data.
Best first request
Call /api/v1/lol/players/{playerId}/form?windows=10,20,50 from your backend and cache the response based on how often that screen changes.
Common fallback
If live data is empty, show today's schedule, upcoming matches, recent results, or the last known team/player rows.
API key handling
Keep the API key on your server. Send your frontend only the fields it needs to render the page.
Use this API for pro matches, teams, players, rosters, stats, and esports history.
If you need Riot ID, PUUID, ranked ladder, champion mastery, or account-linked match history, use Riot's APIs. If you need a pro esports app, use Cito's LoL endpoints.
Pro Esports API
Built for match centers, fantasy products, scouting tools, wikis, dashboards, team pages, player pages, and live bots.
Ranked and Ladder Workflows
Use Riot APIs for direct Riot ID, PUUID, summoner, match history, ranked ladder, champion mastery, and account-linked workflows. Cito only references public pro-player account context where source data allows it.
Docs, examples, and machine-readable endpoint files.
Open the docs when you want examples. Import Postman when you want to test. Use the endpoint manifest when an AI coding tool needs exact paths.
