Endpoint
GEThttps://x402broker.com/v1/fomc-rate-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, crowd-sourced probability estimates for macro, crypto, political, or AI events as priced by Polymarket traders — especially when you want Yes/No implied probabilities, orderbook depth, volume, or whale positioning rather than news sentiment or analyst forecasts. Prefer this over general news APIs when you want market-implied odds rather than qualitative coverage.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Polymarket API downtime or rate limiting causes stale or failed data fetch
- Ambiguous topic keyword matches multiple markets, returning mixed or incorrect results
