Plaid, but for fantasy football. One connect flow for Sleeper, ESPN, and Yahoo — leagues, rosters, and members, dropped into any product with a few lines of code.



Same pattern as Plaid Link — a script tag and a publishable key. No SDK install, no backend proxy required for the widget itself.
<script src="http://localhost:4100/sdk/fantasylink.js"></script>
<script>
FantasyLink.open({
publishableKey: 'pk_live_...',
onSuccess: (data) => {
// { provider, account, league, roster }
},
});
</script>
