FAQ

Questions MarketStack owners ask.

  • 01

    Can I get intraday data for specific time intervals?

    Yes! Use the get_intraday capability. You can specify intervals such as '1min', '5min', '1hour', and up to '24hour' to get precise price movements throughout the trading day.

  • 02

    How do I find which stock exchanges are supported by this server?

    Simply run the list_exchanges capability. It will return a paginated list of all supported global exchanges along with their names, MIC codes, and locations.

  • 03

    Can I filter end-of-day data for a specific date range?

    Absolutely. Both get_eod and get_ticker_eod capabilities accept date_from and date_to parameters in YYYY-MM-DD format to help you analyze specific historical periods.
