How this service works
Search open Polymarket prediction markets by keyword (election, bitcoin, fed, AI...) and get each event's markets with live outcome probabilities, best bid/ask, 24h and total volume, liquidity, end date and link. Use to answer what the market thinks will happen, or to find a market to trade.

Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/predictions/polymarket/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover multiple Polymarket prediction markets matching a topic keyword and want live probability data at scale. Prefer this over the single-market endpoint when you don't have a specific market slug or ID and want to explore what markets exist. Best for answering 'what does the market think about X' questions across a broad topic area.
Side effects
- No markets found for the keyword — returns empty result set
- Query string missing — returns 400 bad request
- Limit out of range (below 1 or above 30) — returns validation error
- Polymarket API upstream unavailable — returns 502/503 error
- Rate limiting or payment verification failure — returns 402 payment required
