Problems to access an API in R-CodePudding

I am trying to download some data from an API. Following the site documentation:

library(jsonlite)
document <- fromJSON("https://api.gurufocus.com/public/user/{your personal token?}/stock/WMT/keyratios");
epv <- document$Valuation$`EPV`
cat(epv)

I inserted my token, but unfortunately, I get this error: Error in open.connection(con, "rb") : HTTP error 404.

Any idea to solve this problem?

Best regards

Up front: remove the {, ?} from the url.

Replace more of the string. If you notice in their examples:

Request
Method    URL
GET       https://api.gurufocus.com/public/user/{your personal token?}/stock/{symbol?}/financials
Example   https://api.gurufocus.com/public/user/{your personal token?}/stock/WMT/financials

The {symbol?} is replaced with WMT. I'm inferring you need to do with same with your token.

If I call

https://api.gurufocus.com/public/user/{abcd1234?}/stock/WMT/financials

(where abcd1234 is a known fake token), I get a 404 Not Found. I believe this is because the question mark breaks the URL into a path component

https://api.gurufocus.com/public/user/{abcd1234

and arguments

}/stock/WMT/financials

However, when I do:

https://api.gurufocus.com/public/user/abcd1234/stock/WMT/financials

I get a 401 Unauthorized, meaning that it parsed a token out of it, found the endpoint, and the token is not sufficient (which I know) to authorize access.
