Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/polymarket-prediction-stream?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live, real-money crowd-sourced probability estimates for macro, crypto, or AI events from Polymarket — especially when you want not just the odds but also volume and whale sentiment as conviction signals. Prefer this over general news or sentiment APIs when you need quantified probability rather than qualitative opinion.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Polymarket API or orderbook data temporarily unavailable — upstream data fetch failure
- Ambiguous topic matches multiple markets — may return the most liquid or first match
- Payment required (HTTP 402) if x402 micropayment not completed before request
- Stale or low-liquidity market returned if topic is niche or thinly traded
