How this service works
PolySignal ranks current Polymarket opportunities by EV, confidence, size hint, risk, and staleness for agent research workflows.
Output
A ranked list of current Polymarket prediction market opportunities, each scored by expected value (EV), confidence, suggested position size hint, risk level, and data staleness — enabling an agent to prioritize which markets to act on.
Example use cases
Top EV opportunities for trading bot
“Give me the top-ranked Polymarket markets by expected value right now so my trading bot can evaluate where to open positions.”
Filtering stale low-risk markets
“Show me the PolySignal rankings filtered for low-risk, non-stale markets — I want to find safe opportunities before they get arbitraged away.”
Daily prediction market briefing
“Fetch the latest PolySignal market rankings and summarize the top 5 opportunities by confidence and size hint for my morning research digest.”
Technical details
Endpoint
GEThttps://polymarket-signal-api.pwnker-polymarket-signals.workers.dev/v1/markets/rankWhen to prefer
Choose this endpoint when you need a pre-scored, ranked view of Polymarket opportunities rather than raw market data — ideal for agent workflows that need to prioritize which markets to research or trade without doing their own EV calculations. Prefer this over raw Polymarket API access when you want aggregated signal (EV, confidence, risk, staleness) in a single call.
Side effects
- No markets returned if Polymarket data feed is unavailable
- Stale scores if upstream data has not refreshed recently
- HTTP 402 if payment of $0.03 USDC is not provided via x402 protocol
- Rate limiting if too many calls are made in quick succession
- Empty ranked list if no markets meet quality thresholds
