Example use cases
FOMC rate decision probability check
“What does Polymarket currently show as the probability of a Fed rate cut at the next FOMC meeting? I want the implied Yes and No odds and volume.”

Technical details
Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/fomc-rate-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events as priced by Polymarket traders — especially when you want market-implied odds (not just news sentiment) and whale order flow signals. Prefer this over news sentiment APIs when you need a quantitative probability, and over general financial data APIs when the question is event-based rather than price-based.
Side effects
- Topic keyword matches no active Polymarket market — empty or null result returned
- Polymarket API upstream outage causing stale or unavailable data
- Ambiguous topic string matching multiple markets with mixed results
- Rate limiting or payment failure resulting in 402 response
- Market has resolved and is no longer active, returning historical rather than live data
