Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/fomc-rate-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market for macro, crypto, political, or AI events. It is especially useful when you want market-implied probabilities (rather than analyst forecasts or model outputs) and when whale/large-trader sentiment is relevant. Prefer this over general news or sentiment APIs when you want financially-incentivized crowd wisdom expressed as Yes/No odds.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Topic string too vague or ambiguous, matching unintended markets
- Polymarket data temporarily unavailable due to upstream API issues — may return stale or error response
- Payment not processed (HTTP 402) if x402 USDC payment is not attached
- Rate limiting if called too frequently without valid payment
