Endpoint
GEThttps://preflight.agentdiet.dev/v1/geopolitical-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, geopolitical, or AI events sourced directly from Polymarket's live orderbooks. Prefer it over news APIs or LLM-generated forecasts when you want market-implied probabilities backed by actual money, volume data, and whale activity. Best used for financial agents, political forecasting bots, or risk assessment workflows that require live, tradeable probability signals rather than static analyst opinions.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Ambiguous topic matches multiple markets — response may return multiple or unexpected markets
- Polymarket API downtime or rate limiting causing stale or missing data
- Payment failure via x402 protocol resulting in 402 response and no data returned
- Topic string too vague to resolve a specific market, leading to low-confidence or mismatched results
