Data has a 15-minute delay and only includes markets with at least 2 trade prints in the window.
Example use cases

Technical details
Endpoint
GEThttps://x402-api-production-266e.up.railway.app/v1/markets/moversWhen to prefer
Use this endpoint when you need a ranked view of which Polymarket markets are experiencing the most significant repricing activity over a specific time horizon. Ideal for identifying breaking-news driven markets, momentum plays, or unusual activity. Prefer this over the whale digest endpoint when you want price-movement ranking rather than volume ranking, and over the raw whale trades endpoint when you need a market-level aggregation rather than individual trade records.
Side effects
- Invalid window param (not 1h/6h/24h) returns error
- No markets with >= 2 prints in window returns empty list
- Payment not attached or insufficient USDC returns 402
- Data delay up to 15 minutes means very recent prints may be missing
- Markets with low liquidity may be absent due to print threshold requirement
