Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/polymarket-prediction-stream?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events from Polymarket's liquid prediction markets. It is especially valuable for gauging market sentiment beyond price charts — capturing implied probabilities and whale behavior that traditional data sources don't provide. Prefer it over general web search when you want structured, quantitative probability data rather than qualitative news articles.
Side effects
- No matching Polymarket market found for the given topic — returns empty or null market data
- Topic query too vague to match a specific market — multiple ambiguous results returned
- Polymarket API or orderbook unavailable — upstream data fetch fails
- Payment not processed (HTTP 402) — x402 micropayment not completed before data is returned
- Rate limiting or quota exceeded on the agentdiet.dev hub — request throttled
