How this service works
Polymarket intelligence for AI agents. Free pulse; paid movers/brief via x402 USDC on Base.
Output
A JSON object containing today's date, a list of notes, payment settlement confirmation, and three structured sections: top-volume markets (question, yes price, 24hr volume), biggest 1-week repricings, and markets resolving within 72 hours — each market entry includes the question text and current yes price.
Example use cases
Daily prediction market morning briefing
“Pull up the latest Catalyst Desk brief and walk me through which prediction markets have the most trading activity today and which ones are about to close.”
Tracking major market repricings
“Check Catalyst Desk for any prediction markets that have moved significantly in price over the past week — I want to know what's shifted and by how much.”
Monitoring near-term market resolutions
“What prediction markets are resolving in the next 72 hours according to Catalyst Desk? I want to know the questions and their current yes prices.”

Endpoint
GEThttps://catalyst-desk.catalystdesk.workers.dev/v1/brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs a rapid, structured snapshot of prediction market activity without having to query individual market APIs. It is ideal for daily briefing workflows, monitoring market sentiment shifts, or identifying near-term resolution events. Prefer it over raw prediction market platform APIs when you want pre-aggregated intelligence across top-volume, repricing, and resolution dimensions in a single call.
Side effects
- Payment not settled — x402 payment of 0.1 USDC required before response is served
- Stale data if underlying prediction market sources are delayed
- Empty sections if no markets meet the threshold criteria (e.g. no major repricings in the past week)
- Network errors from the Cloudflare Workers runtime
- Rate limiting or quota exhaustion on the underlying data sources
