Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/prediction-markets?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from active prediction market traders on Polymarket, especially for macro, crypto, or AI policy events. It is preferable over news sentiment APIs when you want market-implied probabilities backed by actual capital at risk, and over static data sources when freshness and whale-activity signals matter.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Stale or delayed data if Polymarket API is rate-limited or temporarily unavailable
- Ambiguous topic matches multiple markets — may return multiple results requiring disambiguation
- Payment failure via x402 — endpoint returns HTTP 402 if USDC micropayment not completed
- Very niche or newly created markets may have low liquidity or sparse orderbook data
