intraday endpoint missing tickers

[mallikarjkolar]

The API documentation says "the marketstack API also supports intraday data with data intervals as short as one minute. Intraday prices are available for all US stock tickers included in the IEX (Investors Exchange) stock exchange."

I am looking for intraday data for certain tickers that are on the IEX exchange, specifically "BITO", "BITQ", and "VTWO". However, the API doesn't have data for these tickers, and I get the following error: "{"error":{"code":"no_valid_symbols_provided","message":"At least one valid symbol must be provided"}}". Are ALL IEX tickers not available?
