Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/fomc-rate-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction markets — especially for macro events (FOMC, elections), crypto milestones, or AI policy questions. Prefer this over news APIs when you want market-implied probabilities rather than narrative coverage, and over general financial data APIs when the question is event-based rather than price-based.
Side effects
- Topic keyword too vague or ambiguous — may return no matching market or wrong market
- Polymarket API unavailability or rate limiting upstream — may return stale or empty data
- Payment not processed (HTTP 402) — endpoint requires $0.015 USDC payment per call via x402
- Market for the requested topic does not exist on Polymarket — returns empty or null result
- Misspelled or overly specific topic string yields no matching market
