Technical details
Endpoint
GEThttps://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 macro, crypto, political, or AI events as priced by Polymarket traders — especially when you want implied market odds rather than analyst forecasts, and when whale sentiment or trading volume context matters. Prefer this over general news or sentiment APIs when you want a financial-market-derived probability signal for a specific binary outcome.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null market data
- Polymarket API upstream unavailability causing stale or missing data
- Ambiguous topic keyword matching multiple markets — may return aggregate or first-match results
- Payment required (HTTP 402) if x402 micropayment header is not included
- Rate limiting if too many requests are sent in quick succession
