How this service works
Historical price data with configurable timeframes (1H/6H/1D/1W/1M/ALL)
Output
An array of price-timestamp pairs where each entry contains a Unix timestamp (t) and a probability price between 0 and 1 (p), along with the range label used for the query. Suitable for charting or time-series analysis of prediction market probability movements.
Example use cases
Chart monthly probability trend
“Can you fetch the 1-month price history for the Polymarket market 'will-fed-cut-rates-in-december' so I can plot how the probability has shifted over the past few weeks?”
Analyze hourly price movements
“Pull the last hour of price data for Polymarket market ID 'will-spacex-launch-starship-2024' — I want to see if there were any sharp probability swings in the past hour.”
Review all-time market history
“Can you grab the all-time price series for the Polymarket market 'will-ukraine-join-nato' so I can see how the probability has evolved since the market opened?”

Endpoint
GEThttps://polynews.news/api/v1/price-historyWhen to prefer
Use this endpoint when you need raw historical price/probability data for a specific Polymarket prediction market to chart trends, analyze price movements, or feed into further analysis. Prefer this over the catalyst analysis endpoint when you want the underlying data series rather than an AI-generated explanation of price movements.
