Derpibooru Import is running again! All imported content is tagged as 'derpibooru import' and has the original tags.
Welcome to Twibooru! Anonymous posting only; no content restrictions beyond pony-related and legal; comments are disabled by default (Settings -> Comments). Read me!

We provide 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 the site.

The API is similar to that in use on Derpibooru and other Philomena-based boorus. As such, any applications written for that API should be easily modifiable to be compatible with our API.


Licensing of the API is simple — anyone can use it. However, there are some guidelines we ask that you follow:

  • Do not make abusively high numbers of requests. Respect the rate limits.
  • Your application MUST properly cache and respect server-side cache expiry times
  • Your client MUST gracefully back off if requests fail (e.g., non-200 OK HTTP status code), preferably exponentially or fatally
  • Credit SHOULD be given to Twibooru in the form of a link
  • If media is displayed from Twibooru, the artist SHOULD be credited (if available) and you SHOULD display the original source URL with the media, either textually or as a link
  • A link to the post here on Twibooru is optional but suggested
  • We recommend using as the canonical domain
  • The https protocol MUST be specified on all URIs; we do not support plain text HTTP connections


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.

Accessing the API

Most methods support API access by appending the .json extension 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 and can be found by users on their account page. For instance, to access a user's watched feed, the request would be /posts/watched.json?key=xxxxxxxxxxxxxxxxxxxx

Methods dealing with large feeds are paginated; the page parameter controls the page you're on. The number of posts 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.


There is currently only one specific library that has been written for the Twibooru API. You may be able to adapt some of the Derpibooru API libraries listed below and make them work with Twibooru with minor modifications. We haven't tested any of them, so your results may vary. If you want to develop or port one of these to Twibooru, please do so and contact us if you'd like it included in this list.


Method Path Allowed Query Parameters Description Response Format Example
GET /api/v3/posts/:post_id key, filter_id Fetches a post response for the post ID referenced by the post_id URL parameter. {"post":post-response} /api/v3/posts/1

GET /api/v3/posts/:post_id/comments Fetches a list of comment responses representing all comments on the post referenced by the post_id URL parameter. {"comments":[comment-response]} /api/v3/posts/1/comments
GET /api/v3/search/posts key, filter_id, page, per_page, q, sd, sf Executes the search given by the q query parameter, and returns a list of post responses. {"posts":[post-response]} /api/v3/search/posts?q=safe
GET /api/v3/search/tags page, per_page, q Executes the search given by the q query parameter, and returns a list of tag responses, sorted by descending image count. {"tags":[tag-response]} /api/v3/search/tags?q=*wing*

Rate Limits

There are hard rate limits enforced on every API endpoint. Exceeding these limits will result in your requests being throttled until the rate limit is complied with.

You can determine the rate limit and your remaining balance, as well as the time at which the balance will reset, by examining the X-RL, X-RL-Remaining, and X-RL-Reset HTTP headers, respectively. For convenience, here is a list of rate limits:

Endpoint Maximum Requests Period
/api/v3/search/posts 10 1 minute
/api/v3/search/tags 60 1 minute
/api/v3/posts/:id 60 1 minute
/api/v3/posts/:id/comments 60 1 minute


The API may return various HTTP error codes, either due to server or client error. When an error code is returned, the server will respond with a JSON payload containing an error key with a string value, textually describing the error that occured.

Error Code Description Resolution
401 Unauthorized You attempted to retrieve a resource you are not authorized to retrieve. Ensure you have provided appropriate credentials.
404 Not Found You attempted to retrieve a resource that does not exist. Only attempt to retrieve resources that exist.
422 Unprocessable Entity A query was sent to the server in an invalid format (eg: imbalanced parentheses in search term.) Format the query correctly.
429 Too Many Requests Too many queries were sent to the server in too short of a time. Wait some time and re-try the request. Utilize the rate limit headers to avoid encountering this error.
500 Internal Server Error An unknown server-side error occured while processing your request. Contact a site administrator for help.


For embedding content in other websites as well as for finding canonical post descriptors and IDs, we provide an oEmbed API.

This API is compliant with the oEmbed specification and can be found at /oembed.json or /oembed.xml.

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 post's page on Twibooru.

In addition to the standard oEmbed photo attributes, the following attributes are also provided: twibooru_id, twibooru_score, and twibooru_comments

The following domain spaces are supported (for and other domains, the format is the same). /media/ and /img/ URLs are only supported on


For example:

This service supports maxwidth and maxheight parameters; these will return a fully formed thumbnail.

For tools that support it, the Twibooru HTML header is embellished with appropriate oEmbed lookup link tags for automatic oEmbed discovery.
