Endpoint
GEThttps://api.speccy.cloud/v1/predictions/polymarketWhen to prefer
Use this endpoint when you need a ranked snapshot of the top Polymarket prediction markets by trading activity, liquidity, or recency — especially useful for market monitoring, trading research, or surfacing trending forecasting questions. Prefer this over scraping Polymarket directly or building your own aggregation; it delivers structured, ready-to-use data including outcome prices for up to 50 markets in a single call.
Side effects
- Payment failure: x402 payment of $0.01 USDC not completed or invalid — request rejected

- Limit out of range: value below 1 or above 50 returns validation error
- Polymarket data unavailable: upstream API outage may return empty or partial results
