Providers and scope

Choose providers

markets: { categories: ["music"], category: "music_culture", providers: ["kalshi"] }

Need	Setting
Polymarket only (like denpa.ai)	providers: ["polymarket"] (default)
Kalshi station	providers: ["kalshi"] — ids are kalshi-<TICKER>
both exchanges	providers: ["polymarket", "kalshi"]
your own questions	manual markets, resolved through the hub’s claim

The protocol feed (/api/v1/signals/external) is two exchanges: Polymarket carries sports and politics; Kalshi carries music_culture. A categorised getMarketFeed({ category }) defaults to both.

Scope the clock

The hosted program clock programs Polymarket categories; a Kalshi-scoped fork shows permanent TV-static unless it scopes, runs its own clock, or replaces /broadcast.

export default createForkBroadcastPage(config, { categories: ["music", "film"] });

Learn where liquidity is

Sports (FIFA, NBA) first; thin verticals like fashion are event-reactive (no persistent markets between events) and become dedicated forks later on the same core. Always ship a mock or stub fallback when the live market count is 0.
