ResearchBox's API (https://researchbox.org/api_call.php) needs a personal
key, which you can make at https://researchbox.org/api. metacheck reads it from the RESEARCHBOX_API_KEY environment variable,
which you can set in your .Renviron file (usethis::edit_r_environ()):
Details
RESEARCHBOX_API_KEY="your-key"
Setting the key with rbox_token() overrides that for the current session
only. Without a key, rbox_info() and rbox_file_download() read the
box's web page instead, and rbox_files() and rbox_search() are not
available.
aspredicted_info() and the prereg_check module also use the key:
ResearchBox's API serves AsPredicted's public preregistrations. Without a
key, the preregistrations are read from AsPredicted's web pages, and
AsPredicted asks for a captcha after several pages, after which no more are
read.
