Endpoint
GEThttps://bess-x402.onrender.com/v1/predictions/polymarket/top?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time ranked snapshot of the most active or liquid Polymarket prediction markets, especially when filtering by topic (crypto, politics, sports, economy, tech, AI). Prefer this over manually browsing Polymarket when an agent needs programmatic access to current trader sentiment and probabilities across many events at once.
