Endpoint
GEThttps://preflight.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, political, or AI events as reflected in actual money-at-risk on Polymarket. Ideal when you want not just sentiment but implied probability backed by live orderbook liquidity and whale activity, rather than news sentiment or social media polling. Prefer this over general news or sentiment APIs when the user explicitly wants prediction market odds or probability estimates for a future event.
Side effects
- No matching market found for the given topic — returns empty or null market data
- Ambiguous topic keyword matches multiple markets — may return incorrect or unexpected market
- Polymarket API downtime or rate limiting causing stale or missing data
- Misspelled or overly specific topic fails to match any active market
- Topic references a settled or expired market with no live orderbook
