Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/polymarket-alpha?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market — particularly for crypto, macro, AI, or geopolitical events where decentralized market sentiment and whale positioning are valuable signals. Prefer this over news sentiment APIs when you want financially-backed implied probabilities rather than editorial opinion, and over general search when you need quantified Yes/No odds with volume context.
Side effects
- No matching market found for the given topic keyword — returns empty or null results
- Polymarket API downtime or rate limiting causes stale or unavailable data
- Ambiguous topic keyword matches multiple unrelated markets, returning mixed results
- Payment failure via x402 protocol prevents the call from completing
- Very niche or obscure topics may have no active Polymarket market and return no data
