Official League esports data opens to the community on November 14
Riot Games Open Access, powered by GRID, lets students, researchers, hobbyists and early-stage developers build with official LoL esports data from November 14, starting with Worlds 2026. Live series data runs five minutes behind.
Riot is opening up official League of Legends esports data to people outside the pro scene. In an announcement on LoL Esports dated November 12, Riot says Riot Games Open Access, powered by GRID, goes live on Saturday, November 14, the day of the Worlds 2026 final. Students, researchers, hobbyists and early-stage developers can sign up from that day and build with official League of Legends esports data.
What's included
Riot names three things that come with Open Access:
- The Central Data Feed
- The Series State API
- Loopfeed, which Riot lists as part of the Series State API
All of it covers both League of Legends and VALORANT esports matches. Riot's announcement names these products but does not describe what each one contains field by field, so the documentation you get after signing up is where to check before planning a project around a specific stat.
The delay
Live data is not real time. Riot's wording: "Live series data is delayed by five minutes." That delay matters if you were hoping to build anything that reacts to a match as it happens, such as a live companion or second-screen tool. Anything you build on finished series, such as stats pages, analysis or research, isn't affected by it.
Worlds comes first
Riot says "Worlds 2026 will be the first event available through the portal." The subheading frames the launch around the final, saying Open Access gives the community "access to Worlds Final data". The final is Gen.G against Bilibili Gaming on November 14, with Riot's broadcast opening at 2:00 PM ET with the opening ceremony, and our preview of the final has the semifinal scores. The announcement doesn't say which other leagues or events will be added later, and doesn't mention the LCS.
Who it's for, and how to start
Riot lists four groups: students, researchers, hobbyists and early-stage developers. The steps it gives are short: create an account, generate an API key, and use the documentation. Sign-up opens on November 14.
The announcement doesn't mention pricing, rate limits or usage terms, so read GRID's terms when you create your account rather than assuming any of them.
GRID isn't new to League. Riot says GRID has been its official esports data partner since 2023, supplying teams across League and VALORANT esports with data.
Following Worlds on Lolumen
If you just want to follow the final, Lolumen's Worlds page links to the bracket and schedule and has a "Show results" control, so you can choose when to see scores.
