Unofficial R client of the discogs developers API, which can be found here https://www.discogs.com/developers. Using the API, information about releases and the martketplace can be obtained. This package fully supports all functions, including throttling calls and authorization through OAuth or a personalized token.
Installation can be done by using devtools.
install.packages(devtools)
devtools::install_github("Pascallio/discogsAPI")
This package relies on the httr package for making api calls and authorization, and jsonlite for parsing the response into R lists.
While calls can be made without authorization, it limits the amount of calls to 25 / minute, while fully authorized calls increase the amount to 60 / minute. Authorization is therefor strongly recommended.
For personal use, get a personal access token at https://www.discogs.com/settings/developers which can be used to supplement the api calls. An example:
# Get the number for sale for release id '1'
my_token <- "abc123def456"
release <- get_release(1, my_token)
print(release$num_for_sale)
For public use (e.g. an RShiny app), register your application at https://www.discogs.com/settings/developers to obtain an OAuth key and secret. Use these to authorize users using the authorize function. This function will halt the code untill the user has succesfully authorized the app. The Token object returned from the authorize function can be used just as a personal access token:
# Get the number for sale for release id '1'
my_key <- "abcde1234"
my_secret <- "secret9876"
my_token <- authorize(my_key, my_secret)
release <- get_release(1, my_token)
print(release$num_for_sale)
Documentation about each function can be found in the manuals or for complete documentation, see https://www.discogs.com/developers
