Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/predictions/manifold/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need crowd-sourced probability estimates on topics that real-money prediction markets (like Polymarket or Kalshi) don't cover, or when you want a broad range of open questions across AI, tech, science, and politics. Prefer this over financial data APIs for forward-looking probabilistic crowd forecasts rather than historical or market data.

- No matching markets found returns an empty result set
- Manifold Markets API downtime causes upstream failures
- limit out of range (below 1 or above 50) may return an error or be clamped
