library(vagalumeR)

First of all, you'll need one API key, that can be obtained at the Vagalume Website. You'll need to register at the Website for that.

library(tidyverse)
# Copy and paste your api key at the following object:
key <- "putyourapikeyhere"

artists <- c("the-beatles", "madonna", "chico-buarque",
             "the-rolling-stones", "molejo")

artists %>%  map_dfr(artistInfo)

#                 id           name views  pos period uniques points
# 1 3ade68b3gce86eda3    The Beatles 68965   15 201902   30269   42.9
