01 · How it works
EMBED IN THREE STEPS
No backend required. No resolution logic to write. Data decides.
01
CREATE THE MARKET
Use the wizard on FlashCast.social or call the API directly. Pick your question, your data source, and when it closes.
02
EMBED THE WIDGET
Paste one script tag anywhere — your stream overlay, your website, your Discord. The widget handles everything.
03
DATA RESOLVES IT
When the market closes, FlashCast queries the source automatically. No human decides. Points go to winners instantly.
02 · The Widget
ONE SCRIPT TAG. FULLY INTERACTIVE.
Fans predict with points. No money involved. Just bragging rights.
