Is the Api production ready? #30

I've purchased one month to try MarketStack Api and I'm mostly focused on current session intraday data.

Queriying popular symbols (AAPL, MSFT), I get plenty of gaps between bars. I don't get a record for every minute, as expected with such active symbols.

I don't think I'm doing anything wrong. The call is pretty straightforward and I'm using the browser to run the query

https://api.marketstack.com/v1/tickers/aapl/intraday/2021-12-01?access_key=XXXXXXXXXXXXXXXXXXX&interval=1min

If I run the same query, starting date yesterday, there are no gaps in the returned data.

The Api is advertised as real time capable, but so far, that's not been my experience.

Today, 2021-12-02 I've run the same request on AAPL, increasing the limit, and the gaps are still there

I also see many bars returning 'null' in their close value.

Furthermore, I've compared a specific bar with the information in Interactive Brokers and Yahoo Finance, and the results don't match. I've been careful comparing the date (UTC in MarketStack) and Eastern/US in said platforms.

I don't see how this is usable
