If you would like to interact with the API directly without any
helpers, the nhl_get_data() function is made for this
purpose. It takes as input one or more urls (a character vector) and
returns a list of the same length, each element containing the raw
results returned from the API for the corresponding URL.
For example:
library(nhlapi)
urls <- c(
"https://statsapi.web.nhl.com/api/v1/teams/1",
"https://statsapi.web.nhl.com/api/v1/people/8477474"
)
nhl_get_data(urls)

format, the function will by default attempt to flatten nested data
frame columns and return flat data frames where possible. If you really
want raw data returned, you can set the flatten argument to
FALSE:
