Endpoint
POSThttps://onchain-risk.agentdiet.dev/v1/geopolitical-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from a decentralized prediction market, especially for macro, crypto, geopolitical, or AI policy events. It is ideal when you want market-implied odds rather than model-generated forecasts, and when whale sentiment and trading volume provide additional signal. Prefer this over general news search when you need a quantitative probability rather than qualitative coverage.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Ambiguous topic resolves to multiple markets — response may include multiple entries requiring disambiguation
- Polymarket API or data feed downtime causes stale or unavailable data
- Overly broad topic returns too many markets with diluted signal
- Payment not processed via x402 — returns HTTP 402 Payment Required
