Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/fomc-rate-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced implied probabilities and orderbook sentiment from Polymarket for macro, crypto, political, or AI events. Prefer this over news sentiment APIs when you want market-priced probability estimates rather than editorial opinion, and over general financial data APIs when the question is event-based rather than asset-price-based.
Side effects
- Topic keyword does not match any active Polymarket market — returns empty or no-results response
- Polymarket API is temporarily unavailable — upstream timeout or 5xx error
- Payment not processed — HTTP 402 response requiring x402 USDC payment
- Ambiguous topic keyword matches multiple markets — may return aggregated or best-match data
- Market has resolved or expired — returns stale or historical data rather than live odds
