FAQ

Questions Polygon.io owners ask.

  • 01

    Can I get historical price data for a specific stock over a date range?

    Yes. Use the get_aggregates capability by providing the ticker, multiplier, timespan (e.g., 'day'), and the 'from' and 'to' dates. The agent will return the OHLCV bars for that period.

  • 02

    How do I find the description and industry of a specific company?

    Simply use the get_company capability with the stock ticker (e.g., 'AAPL'). It will retrieve the official company metadata, including its business description and industry classification.

  • 03

    Is it possible to see the most recent trades for a ticker?

    Yes! The list_trades capability allows you to fetch tick-by-tick trade data for a specific ticker, showing execution prices and sizes as they happen in the market.
