General rules

Authentication

Authentication is achieved by means of basic HTTP auth or through the use of user token authentication. For this reason, it is recommended to connect through HTTPS. There are no sessions, so every privileged request must be authenticated. Available privileges depend on the user's rank. The way how rank translates to privileges is defined in the server's configuration.

It is recommended to add ?bump-login GET parameter to the first request in a client "session" (where the definition of a session is up to the client), so that the user's last login time is kept up to date.

User token authentication

User token authentication works similarly to basic HTTP auth. Because it operates similarly to basic HTTP auth it is still recommended to connect through HTTPS. The authorization header uses the type of Token and the username and token are encoded as Base64 and sent as the second parameter.

Example header for user1:token-is-more-secure

Authorization: Token dXNlcjE6dG9rZW4taXMtbW9yZS1zZWN1cmU=

The benefit of token authentication is that beyond the initial login to acquire the first token, there is no need to transmit the user password in plaintext via basic auth. Additionally tokens can be revoked at anytime allowing a cleaner interface for isolating clients from user credentials.

Basic requests

Every request must use Content-Type: application/json and Accept: application/json. An exception to this rule are requests that upload files.

File uploads

Requests that upload files must use multipart/form-data encoding. Any request that bundles user files, must send the request data (which is JSON) as an additional file with the special name of metadata (whereas the actual files must have names specific to the API that is being used.)

Alternatively, the server can download the files from the Internet on client's behalf. In that case, the request doesn't need to be specially encoded in any way. The files, however, should be passed as regular fields appended with a Url suffix. For example, to use http://example.com/file.jpg in an API that accepts a file named content, the client should pass {"contentUrl":"http://example.com/file.jpg"} as a part of the JSON message body. When creating or updating post content using this method, the server can also be configured to employ youtube-dl to download content from popular sites such as youtube, gfycat, etc. Access to youtube-dl can be configured with the 'uploads:use_downloader' permission

Finally, in some cases the user might want to reuse one file between the requests to save the bandwidth (for example, reverse search + consecutive upload). In this case one should use temporary file uploads, and pass the tokens returned by the API as regular fields appended with a Token suffix. For example, to use previously uploaded data, which was given token deadbeef, in an API that accepts a file named content, the client should pass {"contentToken":"deadbeef"} as part of the JSON message body. If the file with the particular token doesn't exist or it has expired, the server will show an error.

Error handling

All errors (except for unhandled fatal server errors) send relevant HTTP status code together with JSON of following structure:

{
    "name": "Name of the error, e.g. 'PostNotFoundError'",
    "title": "Generic title of error message, e.g. 'Not found'",
    "description": "Detailed description of what went wrong, e.g. 'User `rr-` not found."
}

List of possible error names:

  • MissingRequiredFileError
  • MissingRequiredParameterError
  • InvalidParameterError (when trying to pass text when integer is expected etc.)
  • IntegrityError (race conditions when editing the same resource)
  • SearchError
  • AuthError
  • PostNotFoundError
  • PostAlreadyFeaturedError
  • PostAlreadyUploadedError
  • InvalidPostIdError
  • InvalidPostSafetyError
  • InvalidPostSourceError
  • InvalidPostContentError
  • InvalidPostRelationError
  • InvalidPostNoteError
  • InvalidPostFlagError
  • InvalidFavoriteTargetError
  • InvalidCommentIdError
  • CommentNotFoundError
  • EmptyCommentTextError
  • InvalidScoreTargetError
  • InvalidScoreValueError
  • TagCategoryNotFoundError
  • TagCategoryAlreadyExistsError
  • TagCategoryIsInUseError
  • InvalidTagCategoryNameError
  • InvalidTagCategoryColorError
  • TagNotFoundError
  • TagAlreadyExistsError
  • TagIsInUseError
  • InvalidTagNameError
  • InvalidTagRelationError
  • InvalidTagCategoryError
  • InvalidTagDescriptionError
  • UserNotFoundError
  • UserAlreadyExistsError
  • InvalidUserNameError
  • InvalidEmailError
  • InvalidPasswordError
  • InvalidRankError
  • InvalidAvatarError
  • ProcessingError (failed to generate thumbnail or download remote file)
  • ValidationError (catch all for odd validation errors)

Field selecting

For performance considerations, sometimes the client might want to choose the fields the server sends to it in order to improve the query speed. This customization is available for top-level fields of most of the resources. To choose the fields, the client should pass ?fields=field1,field2,... suffix to the query. This works regardless of the request type (GET, PUT etc.).

For example, to list posts while getting only their IDs and tags, the client should send a GET query like this:

GET /posts/?fields=id,tags

Versioning

To prevent problems with concurrent resource modification, szurubooru implements optimistic locks using resource versions. Each modifiable resource has its version returned to the client with GET requests. At the same time, each PUT and DELETE request sent by the client must present the same version field to the server with value as it was given in GET.

For example, given GET /post/1, the server responds like this:

{
    ...,
    "version": 2
}

This means the client must then send {"version": 2} back too. If the client fails to do so, the server will reject the request notifying about missing parameter. If someone has edited the post in the mean time, the server will reject the request as well, in which case the client is encouraged to notify the user about the situation.

Webhooks

System administrators can choose to configure webhooks to track events. Webhook URIs can be configured in config.yaml (See config.yaml.dist for example). Upon any event, the API will send a POST request to the listed URIs with a snapshot resource generated with anonymous user privileges as the message body, in JSON format.

API reference

Depending on the deployment, the URLs might be relative to some base path such as /api/. Values denoted with diamond braces (<like this>) signify variable data.

Relations must contain valid post IDs. If <flag> is omitted, they will be defined by default ("loop" will be set for all video posts, and "sound" will be auto-detected). Sending empty thumbnail will cause the post to use default thumbnail. If anonymous is set to truthy value, the uploader name won't be recorded (privilege verification still applies; it's possible to disallow anonymous uploads completely from config.) For details on how to pass content and thumbnail, see file uploads.

Snapshot

Description

A snapshot is a version of a database resource.

    "user":      <issuer>,
    "data":      <data>,
    "time":      <time>
}

Field meaning

  • <operation>: what happened to the resource.

    The value can be either of values below:

    • "created" - the resource has been created
    • "modified" - the resource has been modified
    • "deleted" - the resource has been deleted
    • "merged" - the resource has been merged to another resource

  • <resource-type> and <resource-id>: the resource that was changed.

    The values are correlated as per table below:

    <resource-type> <resource-id>
    "tag" first tag name at given time
    "tag_category" tag category name at given time
    "post" post ID
    "pool" pool ID

  • <issuer>: a micro user resource representing the user who has made the change.

  • <data>: the snapshot data, of which content depends on the <operation>. More explained later.

  • <time>: when the snapshot was created (i.e. when the resource was changed), formatted as per RFC 3339.

<data> field for creation snapshots

The value can be either of structures below, depending on <resource-type>:

  • Tag category snapshot data (<resource-type> = "tag_category")

    Example

    {
    "name":  "character",
    "color": "#FF0000",
    "default": false
}

  • Tag snapshot data (<resource-type> = "tag")

    Example

    {
    "names":        ["tag1", "tag2", "tag3"],
    "category":     "plain",
    "implications": ["imp1", "imp2", "imp3"],
    "suggestions":  ["sug1", "sug2", "sug3"]
}

  • Post snapshot data (<resource-type> = "post")

    Example

    {
    "source": "http://example.com/",
    "safety": "safe",
    "checksum": "deadbeef",
    "tags": ["tag1", "tag2"],
    "relations": [1, 2],
    "notes": [<note1>, <note2>, <note3>],
    "flags": ["loop"],
    "featured": false
}

    <note>s are serialized the same way as note resources.

<data> field for modification snapshots

The value is a property-wise recursive diff between previous version of the resource and its current version. Its structure is a <dictionary-diff> of dictionaries as created by creation snapshots, which is described below.

<primitive>: any primitive (number or a string)

<anything>: any dictionary, list or primitive

<dictionary-diff>:

{
    "type": "object change",
    "value":
    {
        "property-of-any-type-1":
        {
            "type": "deleted property",
            "value": <anything>
        },
        "property-of-any-type-2":
        {
            "type": "added property",
            "value": <anything>
        },
        "primitive-property":
        {
            "type": "primitive change",
            "old-value": "<primitive>",
            "new-value": "<primitive>"
        },
        "list-property": <list-diff>,
        "dictionary-property": <dictionary-diff>
    }
}

<list-diff>:

{
    "type": "list change",
    "removed": [<anything>, <anything>],
    "added": [<anything>, <anything>]
}

Example - a diff for a post that has changed source and has one note added. Note the similarities with the structure of post creation snapshots.

{
    "type": "object change",
    "value":
    {
        "source":
        {
            "type": "primitive change",
            "old-value": None,
            "new-value": "new source"
        },
        "notes":
        {
            "type": "list change",
            "removed": [],
            "added":
            [
                {"polygon": [[0, 0], [0, 1], [1, 1]], "text": "new note"}
            ]
        }
    }
}

Since the snapshot dictionaries structure is pretty immutable, you probably won't see added property or deleted property around. This observation holds true even if the way the snapshots are generated changes - szurubooru stores just the diffs rather than original snapshots, so it wouldn't be able to generate a diff against an old version.

<data> field for deletion snapshots

Same as creation snapshot. In emergencies, it can be used to reconstruct deleted entities. Please note that this does not constitute as means against vandalism (it's still possible to cause chaos by mass editing - this should be dealt with by configuring role privileges in the config) or replace database backups.

<data> field for merge snapshots

A tuple containing 2 elements:

  • resource type equivalent to <resource-type> of the target entity.
  • resource ID euivalen to <resource-id> of the target entity.

Unpaged search result

Description

A result of search operation that doesn't involve paging.

Structure

{
    "results": [
        <resource>,
        <resource>,
        <resource>
    ]
}

Field meaning

  • <resource>: any resource - which exactly depends on the API call. For details on this field, check the documentation for given API call.

Paged search result

Description

A result of search operation that involves paging.

Structure

{
    "query":    <query>,  // same as in input
    "offset":   <offset>, // same as in input
    "limit":    <page-size>,
    "total":    <total-count>,
    "results": [
        <resource>,
        <resource>,
        <resource>
    ]
}

Field meaning

  • <query>: the query passed in the original request that contains standard search query.
  • <offset>: the record starting offset, passed in the original request.
  • <page-size>: number of records on one page.
  • <total-count>: how many resources were found. To get the page count, divide this number by <page-size>.
  • <resource>: any resource - which exactly depends on the API call. For details on this field, check the documentation for given API call.

Image search result

Description

A result of reverse image search operation.

Structure

{
    "exactPost": <exact-post>,
    "similarPosts": [
        {
            "distance": <distance>,
            "post": <similar-post>
        },
        {
            "distance": <distance>,
            "post": <similar-post>
        },
        ...
    ]
}

Field meaning

  • exact-post: a post resource that is exact byte-to-byte duplicate of the input file. May be null.
  • <similar-post>: a post resource that isn't exact duplicate, but visually resembles the input file. Works only on images and animations, i.e. does not work for videos and Flash movies. For non-images and corrupted images, this list is empty.
  • <distance>: distance from the original image (0..1). The lower this value is, the more similar the post is.

Search

Search queries are built of tokens that are separated by spaces. Each token can be of the following form:

Syntax Token type Description
<value> anonymous tokens basic filters
<key>:<value> named tokens advanced filters
sort:<style> sort style tokens sort the results
special:<value> special tokens filters usually tied to the logged in user

Most of anonymous and named tokens support ranged and composite values that take following form:

<value> Description
a,b,c will show things that satisfy either a, b or c.
1.. will show things that are equal to or greater than 1.
..4 will show things that are equal to at most 4.
1..4 will show things that are equal to 1, 2, 3 or 4.

Ranged values can be also supplied by appending -min or -max to the key, for example like this: score-min:1.

Date/time values can be of following form:

  • today
  • yesterday
  • <year>
  • <year>-<month>
  • <year>-<month>-<day>

Some fields, such as user names, can take wildcards (*).

You can escape special characters such as : and - by prepending them with a backslash: \\.

Example

Searching for posts with following query:

sea -fav-count:8.. type:swf uploader:Pirate

will show flash files tagged as sea, that were liked by seven people at most, uploaded by user Pirate.

Searching for posts with re:zero will show an error message about unknown named token.

Searching for posts with re\:zero will show posts tagged with re:zero.
