Endpoint
POSThttps://onchain-risk.agentdiet.dev/v1/election-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from a live prediction market (Polymarket) rather than model-generated forecasts. Ideal for macro, crypto, political, and AI events where you want actual money-backed implied odds, trading volume context, and large-trader sentiment — not just news or analyst opinions.
Side effects
- Topic keyword too vague or not matching any active Polymarket market — returns empty or no-match result
- Polymarket API unavailable or rate-limited — upstream timeout or error response
- Payment not processed via x402 — 402 Payment Required response before data is returned
- Market has resolved and is no longer live — may return stale or closed market data
