Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/polymarket-live-odds-feed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from active prediction market traders, especially for macro events, crypto milestones, AI policy, or geopolitical questions. It is preferred over news sentiment or analyst forecasts when you want market-implied probabilities backed by financial stakes. Best used when you want to understand what informed traders are actually betting on, not just what pundits are saying.
Side effects
- Topic keyword too vague — no matching Polymarket market found, returns empty or error response
- Market topic has low liquidity — probabilities may be unreliable or spread is wide
- Polymarket API unavailable or rate-limited — endpoint returns upstream error
- Query returns stale data if market has recently resolved or been delisted
- Payment failure via x402 — call not executed if USDC micropayment not processed
