Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/macro-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-implied probabilities from Polymarket's prediction market orderbooks for macro, crypto, geopolitical, or AI events — especially when you want actual market-derived probability estimates rather than model forecasts or news sentiment. Prefer this over general news APIs when you need quantified crowd conviction (Yes/No probability percentages) and volume-weighted whale activity signals.
Side effects
- Topic keyword matches no active Polymarket market — returns empty or null results
- Ambiguous topic string matches multiple markets — may return the most popular or first match without disambiguation
- Polymarket API downstream outage — endpoint may return stale or error response
- Very niche or recently created markets may have low liquidity and unreliable implied probabilities
- Payment failure via x402 — call returns HTTP 402 if USDC payment is not properly attached
