How this service works
Polymarket intelligence for AI agents. Free pulse; paid movers/brief via x402 USDC on Base.
Output
A JSON array of ranked prediction market movers, each containing the market question, Polymarket URL, current yes price, 24-hour volume, total liquidity, 1-week price change, end date, and rank. Also includes payment settlement confirmation and product metadata.
Example use cases
Monitoring political market momentum
“Which prediction market events are moving the most this week? I want to see which political or news-driven markets have the biggest 7-day price changes and the most trading volume right now.”
Finding high-liquidity trading opportunities
“Show me the most liquid and active prediction markets today — I want to see the top movers ranked by volume and find where there's real money flowing.”
Tracking breaking-news event markets
“Something big just happened in the news — can you pull up the top prediction market movers to see if any related events are spiking in volume or price right now?”
Technical details
Endpoint
GEThttps://catalyst-desk.catalystdesk.workers.dev/v1/movers?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time ranked snapshot of the most active and fast-moving prediction markets, particularly for surfacing trending events by volume and price momentum. Prefer this over generic financial APIs when the goal is specifically prediction-market intelligence (e.g. Polymarket events), and over manual scraping when you need structured, ranked data with liquidity and price-change signals in a single call.
Side effects
- Payment not settled — x402 micropayment of $0.02 USDC must succeed before data is returned
- Empty or stale data if upstream Polymarket data is temporarily unavailable
- Rate limiting if requests exceed allowed frequency
- Network timeout from the Cloudflare Workers edge environment
