How this service works
Live Polymarket prediction-market data for AI agents: markets closing soon, biggest movers, top by volume ($0.01 each) and a one-call cross-market digest ($0.02). USDC via x402 on Base.
Output
A JSON array of prediction market objects sorted by price movement magnitude, each including the market question, event name, current yes price, best bid/ask, spread, 1h and 24h price change, liquidity in USD, 24h volume in USD, outcome probabilities, Polymarket URL, and end date. Also includes a count, data source label, and generation timestamp.
Example use cases
Track surging political prediction markets
“Which Polymarket prediction markets have surged the most in the last hour? Show me the top 10 with at least $5,000 in 24h volume, moving upward only.”
Spot crashing sports event markets
“What are the Polymarket sports or event markets that have dropped the most in the past 24 hours? Give me up to 25 results, minimum $50,000 in volume.”
Daily briefing on market momentum
“Give me a snapshot of the 15 biggest Polymarket movers in either direction over the last 24 hours, with at least $10,000 in daily volume, so I can see what's shifting.”
Technical details
Endpoint
GEThttps://api.polypulse-x402.workers.dev/v1/markets/movers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to identify which Polymarket prediction markets are experiencing the most significant price movement over a short time horizon (1h or 24h). It is ideal for momentum tracking, anomaly detection, arbitrage signal discovery, or building a live briefing on fast-moving events. Prefer this over the volume or closing-soon endpoints when your primary interest is price velocity rather than market size or urgency.
Side effects
- No markets match the specified filters (e.g. very high min_volume with narrow direction) — returns empty markets array with count 0
- Polymarket Gamma API temporarily unavailable — may return stale cached data (up to 60 seconds old) or upstream error
- Invalid query parameter values (e.g. window not in enum) — likely returns 400 or ignores unknown values
- Payment failure via x402/USDC — request not processed if payment not received
- Rate limiting if many rapid calls are made without successful payment
