FAQ

Questions Polygon.io owners ask.

  • 01

    How can I get historical price data for a specific stock like Apple?

    You can use the get_custom_bars capability. Provide the ticker 'AAPL', a multiplier (e.g., '1'), a timespan (e.g., 'day'), and the date range ('from' and 'to') to receive detailed OHLC and volume data.

  • 02

    Can I check if the stock market is currently open or if there's a holiday?

    Yes. Use get_market_status to see the current state of various exchanges, and get_market_holidays to see upcoming dates when the markets will be closed.

  • 03

    How do I find the ticker symbol for a company if I only know its name?

    Use the list_tickers capability and provide the company name in the search parameter. The agent will return a list of matching tickers along with their primary exchange and asset class.
