Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/fomc-rate-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction markets for macro, crypto, political, or AI events. It is ideal when you want market-implied odds rather than analyst forecasts, especially for FOMC decisions, crypto price milestones, or election outcomes. Prefer this over general news or sentiment APIs when you need quantified probability with volume and whale order flow context.
Side effects
- Topic keyword too vague — returns no matching market or incorrect market
- Polymarket market not found for the given topic — empty or null response
- Payment not processed (HTTP 402) — requires x402 micropayment of $0.01 USDC to proceed
- Rate limiting or upstream Polymarket API outage causing stale or missing data
- Ambiguous topic matching multiple markets — may return wrong event
