Your league's data. Open to build on.
A full REST API sits under your SYTE, serving the same data that builds your Season, Game, Team and Player pages. People have used it to build a fantasy league, broadcast overlays, their own apps. Or don't — most clubs never need to. It's there the day you do.
Data sources & custom pages. Most people live here and never touch code.
For when you want to build something custom. Nobody's forced through this door.
Everything on your site, open to build on.
The API serves the exact data that builds your Season, Game, Team and Player pages. Anything you can see on your SYTE — schedules, standings, rosters, stats, results — is available through it. Not a locked box with a CSV export bolted on; your live data is genuinely open.
The same data that runs your site runs everything people build on it. It exposes your scoring & stats and competition data.
Look what people have already built.
Real, named things built on the XSYTE / HockeySYTE API by the community — not XSYTE's own features. Screenshots beat any "here's what's possible" list.
QSL Fantasy Hockey League
Built by Adrian Madden (Skate Queensland) — a full fantasy competition running off live HockeySYTE data.
Broadcast graphics — scores, periods, player names, goal & penalty events — driven by live game data. Seen on the IceHQ YouTube channel.
Real-time, easy-to-read player and game stats for commentators — sorted for quick reference during live commentary.
Combines multiple team schedules from different sites into one consolidated view, with export to Google Calendar.
These are third-party / community builds on the API — distinct from XSYTE's own built-in GameDay features (scoreboard, Showtime), which run on a separate realtime service, not the API.
Pick the door that suits you.
No-code Data Sources
Pull live Products, Teams, Divisions, Seasons, Standings and Schedules straight into your pages — no code at all. It's how ACC shows live available-team-slots.

When you want to go further, the whole thing is open to developers — the same endpoints behind every public page, ready to build on.
Read the API docs You've still got options.
You don't need to hire anyone. Claude can build against the API for you — describe what you want and let AI wire it up. And if you'd rather have a hand, there's a real human (and a founder) who'll point you the right way. The API is an open door, not a barrier.
