How to use this Tool
Use the deployed input fields below. Required fields must be supplied; optional filters narrow the result.
queryParams.end_time (Optional): End time (Unix seconds). 0 means current time. Cache aligns to 5-minute buckets, so two requests within the same bucket return the same cached result.
queryParams.interval (Optional): Candle interval in minutes: 1=1min, 60=1hour, 1440=1day. Defaults to 60.
queryParams.start_time (Optional): Start time (Unix seconds). 0 means no lower bound. Cache aligns to 5-minute buckets, so two requests within the same bucket return the same cached result.
What this Tool returns
Returns Polymarket OHLCV candles with the condition identifier, interval and candle timestamps.
Response fields and how to read them
The table follows the official response contract, including nested fields and useful response metadata. [] denotes an array item. Required means required within its parent object, not that a conditional parent always exists. A nullable type permits null; an optional field can be absent. Use the documented conditions below to distinguish missing, empty and zero values. Units and reporting windows apply only where explicitly documented.

Coverage, units and freshness
A condition ID identifies the market; it differs from an outcome token ID. Read the documented candle unit and coverage before comparing outcomes.
Inspect any returned observation time, cache status, watermark, pagination and errors using their documented meanings. A successful request alone does not establish complete coverage. Where no freshness or completeness guarantee is documented, treat it as unknown. Saved Examples are historical and viewing them does not refresh data or execute a new call.
