Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/polymarket-alpha?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, crowd-sourced probability estimates for macro, crypto, or AI events sourced directly from Polymarket's live orderbooks — especially when you want implied probabilities with volume and whale sentiment context rather than just news sentiment or analyst forecasts. Prefer this over general news APIs or sentiment tools when the user explicitly wants prediction market odds or crowd-wisdom probability for a binary outcome event.
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 markets — may return the most liquid or recent match
- HTTP 402 payment required if x402 payment header is missing or insufficient
- Rate limiting or quota exhaustion if called at high frequency
