How do stock trading companies, like Robinhood, get access to the NASDAQ and NYSE? Is there an API that allows anyone to connect to these exchanges?

There are many 'private' API's companies use to exchange data. So it's not 'anyone', but it often is 'an API'. But you won't be able to access these private API's without signing a contract (and generally paying money).
