Technical details
Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/fomc-rate-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-wisdom probabilities from Polymarket's prediction markets for macro events (FOMC, elections, recession), crypto milestones (ETF approvals, protocol upgrades), or AI policy events. Prefer this over news sentiment APIs when you want market-implied probabilities backed by real money and volume, rather than media tone. Best for agents that need a quantitative probability estimate from decentralized prediction markets rather than qualitative analyst opinion.
Side effects
- Topic keyword does not match any active Polymarket market — returns empty or null results
- Polymarket API unavailable or rate-limited — upstream data fetch failure
- Vague or ambiguous topic string returns unrelated market data
- Payment not completed via x402 — returns HTTP 402 Payment Required
- Market has resolved or closed — returns historical rather than live data
