Technical details
Endpoint
GEThttps://api.predge.io/v1/markets/%7BconditionId%7D/historyWhen to prefer
Choose this endpoint when you need granular per-trade whale intelligence for a specific Polymarket market identified by its conditionId, including wallet quality scores and bucketed volume trends. Prefer this over generic on-chain data sources when you want pre-computed whale scoring, win-rate context, and insider-flow heuristics rather than raw blockchain transaction data.
Side effects
- Invalid or malformed conditionId returns a 404 or empty market response
- Unknown conditionId for a market not tracked by Predge returns no data
- Invalid window enum value (e.g. not 7d/30d/all) may return a 400 error
- Market with no trades in the requested window returns empty trades array
- Payment not received (x402 protocol failure) results in 402 response requiring USDC payment
- Rate limiting or plan quota exceeded may result in 429 response
