tq_exchange("NASDAQ") not working

[mdancho84]

I'm getting the following error. It looks like 403 meaning access is being prevented. Any alternatives for getting exchange data for NASDAQ, AMEX, and NYSE?

tq_exchange("NASDAQ")
Getting data...

Error in open.connection(con, "rb") : 
  cannot open the connection to 'https://api.nasdaq.com/api/screener/stocks?tableonly=true&exchange=nasdaq&download=true'
In addition: Warning message:

Seems like anti-scraper filter? I can reach URL from browser but not from curl.

Following for updates (and I will see if I can get anything to work).

Has this issue been sorted out? Its not giving for AMEX and NYSE exchange data also.

Has this issue been resolved or looked at?

yes, looks like an anti-spam filter is there.

api.nasdaq.com - sever is allowing only few values as 'User Agent' in the http request header.
below are the allowed values as user agent
{
"user-agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/113.0.0.0 Safari/537.36"
}

modify package in local machine to make HTTP call with above mentioned user-agent

I will test this out. Thanks a lot. 😀
