Derpibooru provides a JSON API for major site functionality, which can be freely used by anyone wanting to produce tools for the site or other webapps that use the data provided within Derpibooru.
Licensing of the API is simple - anyone can use it, users making abusively high numbers of requests may be asked to stop. Your application MUST properly cache, respect server-side cache expiry times. Your client MUST gracefully back off if requests fail (eg non-200 HTTP code), preferably exponentially or fatally.
Credit MUST always be given to the site in the form of a link. If images are used, the artist MUST always be credited (if provided) and the original source URL MUST be displayed alongside the image, either in textual form or as a link. A link to the Derpibooru page is optional but recommended; we recommend the derpibooru.org domain as a canonical domain. The https protocol MUST be specified on all URIs; Derpibooru does not support plaintext HTTP connections.
Accessing the API
Most methods support API access by appending the extension .json to a URL. For requests that require authentication, the URL parameter "key" should be appended. This key provides limited access to a user"s account. This key can be found by users on their account page. For instance, to access a user"s watched feed, the request
/images/watched.json?key=xxxxxxxxxxxxxxxxxxxx would be made.
Methods dealing with large feeds are paginated; the "page" parameter controls the page you're on. The number of images per page can be set with the "perpage" parameter. The default is 15 unless you use your key and have changed the "Images per page" option on the settings page.
Search endpoints are controlled by the current user's filter (or the default, if no key is supplied); if you wish to use a custom filter, you can use the "filter_id" parameter.
Some developers have written libraries for the Derpibooru API and made them available. Please contact us if you'd like yours listed here.
Basic methods for fetching image lists and information are available. To access the JSON API for a given image page, simply add
to the end of the path. Here are a few incredibly exciting examples.
Note the list pages default to a 7 day sampling period; this can be altered with a URL parameter such as 6h, 24h, 7d, 4w.
Authenticated requests take a key argument. Fill this in with your personal API key.
All page parameters are 1-indexed.
Image Index (
||The page offset. (The number of images per page is taken from user settings. For unauthenticated requests, the default value is 15.)|
||When set, includes limited information about deleted and duplicate images in the results. For such images, metadata is limited to id, created_at, updated_at, and either deletion_reason or duplicate_of.|
||When set, order the images randomly.|
Image Search (
||The search query. (Replace spaces with "+".)|
||The page offset. (Refer to Image Index section for more information.)|
||How many results to return on each page (must be between 1 and 50).|
For embedding content in other websites as well as for finding canonical image descriptors and IDs, we provide an oEmbed API.
Format selection is done by URL; call oembed.xml for an XML response. This is the only API currently supporting XML and we strongly encourage the use of JSON wherever possible.
You are strongly advised to cache response data on your own server upon embedding content via oEmbed, particularly if your website supports a large number of users. A cache age parameter is provided, which your client SHOULD respect for oEmbed requests themselves.
The author_url and author_name attributes will be set to the original author/source URL attributes wherever possible. The provider_url attribute will always direct you to the image's page on Derpibooru.
In addition to the standard oEmbed photo attributes, the following attributes are also provided: derpibooru_id, derpibooru_score, derpibooru_comments
The following domain spaces are supported (for derpibooru.org and other domains, the format is the same). /media/ and /img/ URLs are only supported on derpicdn.net.
This service supports maxwidth and maxheight parameters; these will return a fully formed thumbnail.
For tools that support it, the Derpibooru HTML header is embellished with appropriate oEmbed lookup link tags for automatic oEmbed discovery.
