Technical details
Endpoint
POSThttps://polymarket-odds.agentdiet.dev/v1/polymarket-prediction-stream?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for binary macro, crypto, geopolitical, or AI events — especially when you want market-implied odds rather than model-generated forecasts. Prefer this over news sentiment APIs when you want actual money-weighted conviction signals, and over static data sources when you need live orderbook depth and whale activity. Best suited for agents making decisions that benefit from knowing what sophisticated traders are collectively pricing in for near-term events.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Polymarket API or orderbook data temporarily unavailable — upstream timeout or connection error
- Ambiguous topic keyword matching multiple markets — may return multiple results or best-guess match
- Payment failure via x402 protocol — call not executed if USDC micropayment rejected
- Stale or low-liquidity market data for niche topics — probabilities may not reflect active trading
