Choose LoL

Use One Game Starter when the product is League of Legends-only. It includes commercial use and LoL webhook access without paying for every game.

Create webhook

Add your endpoint in the dashboard and subscribe to the exact LoL events your product needs.

Filter stream

Use filters such as league, matchId, gameId, or side so your backend receives the updates it actually cares about.

Verify delivery

Use X-Cito-Signature to verify payloads and X-Cito-Event-Id as your idempotency key. Failed deliveries retry up to 3 times.

Endpoint chain

Start with /api/v1/lol/schedule/upcoming?leagueSlug=msi, 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.

GET
/api/v1/lol/schedule/upcoming?leagueSlug=msi

MSI international match data.

Upcoming MSI matches

/api/v1/lol/schedule/upcoming?leagueSlug=msi

Use this first when the page needs msi international match data.

Live MSI matches

/api/v1/lol/live?leagueSlug=msi

Live MSI matches fills in the detail around the primary response.

Team roster at MSI

/api/v1/lol/teams/{slug}/roster

Team roster at MSI fills in the detail around the primary response.

Returned data

Fetch MSI match results, group stage data, bracket stage results, team rosters, player stats, and live match state during the League of Legends Mid-Season Invitational.

Best first request

Call /api/v1/lol/schedule/upcoming?leagueSlug=msi 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.

Live matches and schedules
Pick/ban and game stats where published
Tournament brackets and standings
Player earnings and org history
Transfer tracking
Roster history

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.
