How this service works
Polymarket odds movers: active markets ranked by biggest price swing in the last 1h / 24h / 1wk (window param), with yes price, change and direction, best bid/ask, spread, 24h volume, liquidity and end date.
Output
A JSON object with an ok flag, the time window used, total markets scanned, a ranked list of up to 50 movers each containing the market slug, question text, yes price, price change, direction (up/down), bid/ask spread, 24h volume in USD, liquidity in USD, and end date — plus aggregate counts of up vs down movers and the single biggest absolute move observed.
Example use cases
Hourly prediction market alert scan
“Check Polymarket right now and show me the top 10 markets that have moved the most in the last hour — I want to see price change, direction, and spread for each.”
Weekly big-mover research digest
“Give me the 15 biggest Polymarket movers over the past week with at least $50,000 in 24h volume — I'm trying to spot which political or economic events have had the most dramatic probability shifts.”
Liquid market momentum screen
“Pull up the top 25 Polymarket markets ranked by biggest 24-hour price swing, filtering out anything with less than $20,000 in daily volume — I want yes price, change percentage, and how much liquidity each market has.”

Endpoint
POSThttps://polymarket-odds-movers.hergertsynthora.com/serviceWhen to prefer
Use this endpoint when you need a pre-ranked, real-time snapshot of which Polymarket prediction markets are experiencing the most significant price movement over a specific window, rather than querying individual market prices or doing your own sorting. It is ideal for trend detection, alerting workflows, momentum screens, and research digests that need volume-filtered, liquid markets with directional context — all in one structured response.
Side effects
- Invalid window value (not 1h, 24h, or 1wk) may return an error or default behavior
- limit outside 1-50 range may be clamped or rejected
- min_volume set very high may return zero results
- Polymarket data source unavailable causes fetch failure
- Network timeout on the hergertsynthora.com host
