Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/polymarket-prediction-stream?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates for specific macro, crypto, political, or AI events as priced on Polymarket. Prefer this over general news or sentiment APIs when you want market-implied probabilities backed by actual money and orderbook depth, rather than opinion or social sentiment. Especially useful when whale positioning or volume context is needed alongside raw odds.
Side effects
- No matching Polymarket market found for the given topic — returns empty or null result
- Topic keyword too vague, returns multiple unrelated markets
- Market may be resolved/closed, returning stale or terminal data
- Payment required (HTTP 402) if x402 micropayment is not fulfilled
- Rate limiting if called too frequently without valid payment credentials
- Orderbook data may have slight latency during high-volatility events
