# frozen_string_literal: true
# A client for Pixiv's AJAX API.
#
# Notes on the API:
#
# * The user agent must be spoofed as a browser user agent, otherwise the API
# will return an error.
# * You must authenticate by passing a PHPSESSID cookie, otherwise the API will
# return nothing for R-18 works.
# * The PHPSESSID cookie is obtained by logging in manually and getting the
# cookie from the devtools.
# * The /ajax/illust/$id endpoint only returns the first image for multi-image
# works. The /ajax/illust/$id/pages API must be used to get the full list of images.
# * Ugoiras need to use the /ajax/illust/$id/ugoira_meta API to get the frame metadata.
#
