How this service works
Price/volume history for one Polymarket market (path param: 0x… condition id). Trade-print price series in daily buckets (price normalized to the YES side, NOT orderbook quotes — outcome_verified.flow: false) with per-bucket volume and whale volume, plus up to 200 individual prints; includes resolution/resolved_at straight off the markets row when settled (outcome_verified.resolution: true). Query param: window (7d|30d|all, default 30d — "all" bounded to 180 days). 15 min delay. 404 (not charged) if unknown.
Output
A time series of daily price buckets with YES-normalized trade-print prices (not orderbook quotes), per-bucket total volume, and per-bucket whale volume; up to 200 individual trade prints; and resolution metadata (resolved boolean, resolved_at timestamp) when the market has settled. Data has a 15-minute delay.
Example use cases
Whale activity spike investigation
“For Polymarket condition 0xabc123..., get me the 7-day trade history and show me how much of the volume came from whale wallets each day — I want to know if whales piled in recently.”
Resolved market outcome lookup
“Did Polymarket market 0xdef456... resolve? If so, when and what was the outcome? Pull its full history so I can see the price leading up to resolution.”
Long-term market trend analysis
“Give me the full 180-day price and volume history for Polymarket condition 0x789xyz... — I want to chart how the YES probability drifted over time and identify any big volume days.”
Technical details
Endpoint
GEThttps://api.predge.io/v1/markets/:conditionId/historyWhen to prefer
Use this endpoint when you need historical trade-print price and volume data — especially whale volume — for a specific Polymarket market identified by its 0x condition ID. Prefer it over generic Polymarket APIs when whale-segmented volume and insider-signal context are needed alongside price history, or when you need resolution status directly from the markets row.
Side effects
- 404 returned (not charged) if the condition ID is unknown or not tracked by Predge
- Invalid window enum value may result in a 400 or defaulting to 30d
- 'all' window is capped at 180 days regardless of market age
- Stale data up to 15 minutes behind real-time trades
