How this service works
Ranked feed of the most active prediction markets across Polymarket and Kalshi. Each entry carries a composite heat score plus the components behind it: 24h volume, volume-spike multiplier, liquidity, order-flow bias, whale activity and current YES price. Filter by category, platform or minimum volume. Served from a cached feed; updated_at is its age. Billed on success, including an empty result. JSON.
Output
A JSON object with an array of ranked market entries (up to 50) and a feed timestamp. Each market includes: market_id, platform, question text, composite heat_score (0–1), volume_24h (USD), volume_spike_x multiplier, liquidity_usd, price_yes, flow_bias (buy/sell/neutral), whale_activity object, hours_to_resolve, category tags, and human-readable signal sentences explaining the heat score components.
Example use cases
Spot trending crypto prediction markets
“What are the top 10 hottest crypto prediction markets on Polymarket right now? I want to see the heat score, volume spike, and whether order flow is leaning buy or sell.”

“Pull the hottest political prediction markets across both Polymarket and Kalshi — up to 20 of them — and flag any that have whale activity. Only show markets with at least $5,000 in 24h volume.”

Technical details
Endpoint
GEThttps://api.scanna.xyz/hotWhen to prefer
Use this endpoint when you need a pre-ranked, multi-signal view of the most active prediction markets across both Polymarket and Kalshi in a single call. It is superior to querying each venue's raw API separately because it normalizes volume, applies spike detection, adds whale activity and order-flow signals, and computes a composite heat score — saving significant aggregation work. Prefer it over Scanna's individual market endpoints when you want a discovery feed rather than data on a known market_id.
Side effects
- Empty markets array returned if no markets meet filter criteria — still billed
- Stale data: updated_at may lag by minutes due to caching; not real-time tick data
- Invalid platform enum value returns a validation error
- min_volume or limit out of allowed range returns a 400-level error
- Network or upstream venue outage may cause feed to serve a very stale snapshot
