API

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 web applications that use the data provided within Derpibooru.

Note that if you are looking to continuously scrape the entire website, we offer nightly database dumps instead. Consider if these suit your needs first, then rely on the API if they do not.

Licensing

Anyone may use the API. Users making abusively high numbers of requests or excessively expensive requests will be asked to stop, and banned if they do not. Your application must properly cache, and respect server-side cache expiry times. Your client must gracefully back off if requests fail, preferably exponentially or fatally.

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 URLs.

Parameters

This is a list of general parameters that are useful when working with the API. Not all parameters may be used in every request.

Name	Description
filter_id	Assuming the user can access the filter ID given by the parameter, overrides the current filter for this request. This is primarily useful for unauthenticated API access.
key	An optional authentication token. If omitted, no user will be authenticated. You can find your authentication token in your account settings.
page	Controls the current page of the response, if the response is paginated. Empty values default to the first page.
per_page	Controls the number of results per page, up to a limit of 50, if the response is paginated. The default is 25.
q	The current search query, if the request is a search request.
sd	The current sort direction, if the request is a search request.
sf	The current sort field, if the request is a search request.
