Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/polymarket-prediction-stream?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction markets for macro, crypto, geopolitical, or AI events. Prefer this over static news APIs or sentiment tools when you want market-implied probabilities backed by actual financial stakes and volume. Ideal for agents that need to factor crowd wisdom and whale positioning into decision-making rather than relying on opinion polls or news headlines.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Stale or delayed data if Polymarket API is experiencing downtime
- Ambiguous topic string matching multiple unrelated markets — may return multiple or incorrect market results
- Payment failure via x402 if insufficient USDC balance — returns 402 status
- Rate limiting if the same topic is queried too frequently in rapid succession
