for image in Search().query("rarity", "twilight sparkle"):
  print(image.url)

Crawling Derpibooru from first to last post

from derpibooru import Search

# This is only an example and shouldn't be used in practice as it abuses
# Derpibooru's licensing terms
for image in Search().ascending().limit(None):
  id_number, score, tags = image.id, image.score, ", ".join(image.tags)
  print("#{} - score: {:>3} - {}".format(id_number, score, tags))

Getting random posts

from derpibooru import Search, sort

for post in Search().sort_by(sort.RANDOM):
  print(post.url)

Getting top 100 posts

from derpibooru import Search, sort

top_scoring = [post for post in Search().sort_by(sort.SCORE).limit(100)]

Storing and passing new search parameters

from derpibooru import Search, sort

params = Search().sort_by(sort.SCORE).limit(100).parameters

top_scoring = Search(**params)
top_animated = top_scoring.query("animated")

Filtering by metadata

from derpibooru import Search, query

q = {
  "wallpaper",
  query.width == 1920,
  query.height == 1080,
  query.score >= 100
}

wallpapers = [image for image in Search().query(*q)]

Getting the latest images from a watchlist

from derpibooru import Search, user

key = "your_api_key"

for post in Search().key(key).watched(user.ONLY):
  id_number, score, tags = post.id, post.score, ", ".join(post.tags)
  print("#{} - score: {:>3} - {}".format(id_number, score, tags))
