Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/market-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, crowd-sourced implied probabilities for macro, crypto, AI, or geopolitical events from Polymarket's prediction market — especially when you want orderbook depth, volume signals, and whale sentiment rather than just a headline odds number. Prefer this over news sentiment analysis when you want market-priced probability estimates rather than editorial opinion.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Ambiguous topic resolves to multiple markets — may return aggregated or first-match data
- Stale or delayed data if Polymarket API is experiencing latency
- Payment failure via x402 protocol if USDC balance is insufficient
- Rate limiting if too many requests are made in quick succession
