CheckFace based on hash for this page

Using the CheckFace API

The API is available at https://api.checkface.ml/

You’re in luck that it’s not authenticated; it’s an entirely open API!

The API is in Alpha is is likely to go down, have maintenance at unpredictable times and make breaking changes to the API.

Endpoints

/status/

Returns a http 200 success if the API is available

/api/face/

Generate a single image Use either value, seed or guid parameters to specify the face

Query Parameters

dim optional int between 10-1024

value optional string is any free text such as the hash of a file

seed optional int corresponding to the seed used in the random number generator to generate latents

guid optional guid globally unique identifier returned by /api/registerlatent

format optional string if set to webp, returns a webp image. Defaults to jpg

Returns

An image

Example

https://api.checkface.ml/api/face/?value=example&dim=500&format=webp

/api/hashdata/

Get the latent Use either value, seed or guid parameters to specify the latent

Query Parameters

value optional string is any free text such as the hash of a file

seed optional int corresponding to the seed used in the random number generator to generate latents

guid optional guid globally unique identifier returned by /api/registerlatent

Returns

Json object with data about the latent used for the given value

{
    "qlatent": [0.4221103225421117,-0.31882407908604915,0.36004541443342347,...],
    "seed": 78062172
}

Example

https://api.checkface.ml/api/hashdata/?value=example

/api/morphframe/

Returns a single frame from a morph. Can be used to get the midpoint,

Use from_* and to_* parameters to specify the start and end points of the morph. You can mix and match values, seeds and guids.

Query Parameters

dim optional int between 10-1024 is the size of the gif in px

num_frames optional int between 3-200 is the number of frames. Defaults to 50

frame_num int between 0 to (num_frames-1) specify the specific frame to return

linear boolen set true for a linear morph from start to end rather than trig based

from_value, to_value optional string is any free text such as the hash of a file

from_seed, to_seed optional int corresponding to the seed used in the random number generator to generate latents

from_guid, to_guid optional guid globally unique identifier returned by /api/registerlatent

Returns

An image

Example

https://api.checkface.ml/api/morphframe/?from_value=example&to_value=yeet&frame_num=25&linear=true

/api/gif/

/api/webp/

Creates a gif or animated webp morphing between two images. Use either from_* and to_* parameters to specify the start and end points of the morph. You can mix and match values, seeds and guids.

Query Parameters

dim optional int between 10-1024 is the size of the gif in px

fps optional int between 1-100 is the frames per second

num_frames optional int between 3-200 is the number of frames in the gif

from_value, to_value optional string is any free text such as the hash of a file

from_seed, to_seed optional int corresponding to the seed used in the random number generator to generate latents

from_guid, to_guid optional guid globally unique identifier returned by /api/registerlatent

Returns

A gif or animated webp

Examples

  1. https://api.checkface.ml/api/gif/?from_value=example&to_value=yeet&dim=400&fps=16&num_frames=80
  2. https://api.checkface.ml/api/webp/?from_value=example&to_value=yeet&dim=400&fps=16&num_frames=80

/api/mp4/

Creates an mp4 morphing between two images.

Use either from_* and to_* parameters to specify the start and end points of the mp4. You can mix and match values, seeds and guids.

Setting embed_html=true embeds the video in an HTML document, which automatically loops the video like a gif. This is useful when trying out the api in a browser manually.

Query Parameters

dim optional int between 10-1024 is the size of the mp4 in px

fps optional int between 1-100 is the frames per second

num_frames optional int between 3-200 is the number of frames in the mp4

from_value, to_value optional string is any free text such as the hash of a file

from_seed, to_seed optional int corresponding to the seed used in the random number generator to generate latents

from_guid, to_guid optional guid globally unique identifier returned by /api/registerlatent

embed_html optional boolean determines whether the response is embedded in an HTML document and loops

Returns

If embed_html=true, returns an html document, otherwise returns an mp4 video.

Examples

  1. https://api.checkface.ml/api/mp4/?from_value=example&to_value=yeet&dim=400&fps=16&num_frames=80
  2. https://api.checkface.ml/api/mp4/?from_value=example&to_value=yeet&dim=400&fps=16&num_frames=80&embed_html=true

/api/linkpreview/

Creates an image with each endpoint and the midpoint. Intented to be used as the link preview for a morph.

Use from_* and to_* parameters to specify the start and end points of the mp4. You can mix and match values, seeds and guids.

Query Parameters

width optional int between 100-1400 is the width of the image in px. Defaults to 1200 width and height of 628

from_value, to_value optional string is any free text such as the hash of a file

from_seed, to_seed optional int corresponding to the seed used in the random number generator to generate latents

from_guid, to_guid optional guid globally unique identifier returned by /api/registerlatent

Returns

An image

Example

https://api.checkface.ml/api/linkpreview/?from_value=example&to_value=yeet

POST /api/registerlatent/

POST json to this endpoint to register a latent for later use. It returns a guid which can be used later in guid parameters.

Use content type application/json.

Body

The body should be a json object:

{
    "latent": [0.12135718, -0.41143386,  0.77926035,...],
    "type": "test"
}

Returns
