Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/polymarket-prediction-stream?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market orderbooks, especially for crypto, macro, or AI events. Prefer this over general news or sentiment APIs when you specifically want implied market probabilities, whale positioning, and trading volume rather than editorial opinion or social media sentiment.
Side effects
- Topic keyword too vague or ambiguous — returns no matching markets or mismatched markets
- Polymarket API upstream unavailability — endpoint may return empty or error response
- Topic not currently listed on Polymarket — no active market found
- Rate limiting or payment failure (x402) — request blocked until payment resolved
- Stale data if Polymarket orderbook feed is delayed
