Avatar WEB API

Contents

1   API basics

Root API URL: https://api.avatarsdk.com/

API endpoints produce JSON responses unless stated otherwise. Please see Content-Type HTTP Header for particular response format.

All POST requests accept multipart/form-data unless stated otherwise.

All mesh/pointcloud retrieval endpoints produce zip archive with mesh/pointcloud in binary PLY format unless stated otherwise.

1.1   Authentication with OAuth 2.0

Before any of the API methods can be used, you should generate an application identifier (referenced later as client_id) for your app. This identifier is used to obtain the access token which is then used to sign actual API requests. You could use one of the official libraries listed on OAuth site (recommended) or any other on your taste to add OAuth 2.0 support in your app.

In order to get your client_id and client_secret please sign up for AvatarSDK developer account.

Besides client_id and client_secret (depending on application authorization grant type) you will need following settings:

For more information on grant types see section 4 of OAuth 2.0 RFC document.

1.3   Filtering

Results of list-retrieving requests may be filtered by some fields of requested objects (e.g. creation time, status, etc.) by specifying filters as a query parameter. All filters are case-insensitive unless stated otherwise. Filters may be specified several times. In this case, they all will be joined via logical AND. See example below:

$ curl -v -H "Authorization: Bearer F88pQWs8hoPzbeCg4xTGifDxxs1eKu" -X GET "https://api.avatarsdk.com/avatars/?status=completed&description=fb"
> GET /avatars/?status=completed&description=fb HTTP/1.1
> User-Agent: curl/7.35.0
> Host: api.avatarsdk.com
> Accept: */*
> Authorization: Bearer F88pQWs8hoPzbeCg4xTGifDxxs1eKu
>
< HTTP/1.0 200 OK
< Date: Mon, 03 Apr 2017 04:08:15 GMT
< Link: <https://api.avatarsdk.com/avatars/?description=fb&status=completed>; rel="first", <https://api.avatarsdk.com/avatars/?description=fb&page=1&status=completed>; rel="last"
< Vary: Accept, Cookie
< Content-Type: application/json
< Allow: GET, POST, HEAD, OPTIONS
<
[...]

Please see filters section in particular request documentation to find available filters.

1.4   Developer/Client access

API has two different access modes: developer and client access. Client access mode is slightly more restricted in terms of access to some methods: e.g. it is restricted to list all avatars created with the same client_id and allowed to list only those created with the same PlayerUID, etc.

Please see detailed description for each particular method to find more information about available access modes and its restrictions.

It is highly recommended to use Client access in applications released into production: malicious users won't be able to access or delete data of other users even if client_id and client_secret are compromised.

Client access mode requires to sign each request with PlayerUID identifier along with OAuth access token. To do this you need to register PlayerUID once per unique application (e.g. on the first launch) and then sign each request with this PlayerUID via X-PlayerUID HTTP header. See example below:

$ curl -v -H "Authorization: Bearer F88pQWs8hoPzbeCg4xTGifDxxs1eKu" -H "X-PlayerUID: 9418fd52-baef-401c-a2b3-e6fe16d93596" -X GET "https://api.avatarsdk.com/avatars/"
> GET /avatars/ HTTP/1.1
> User-Agent: curl/7.35.0
> Host: api.avatarsdk.com
> Accept: */*
> Authorization: Bearer F88pQWs8hoPzbeCg4xTGifDxxs1eKu
> X-PlayerUID: 9418fd52-baef-401c-a2b3-e6fe16d93596
>
< HTTP/1.0 200 OK
< Date: Mon, 03 Apr 2017 04:08:15 GMT
< Vary: Accept, Cookie
< Link: <https://api.avatarsdk.com/avatars/>; rel="first", <https://api.avatarsdk.com/avatars/?page=1>; rel="last"
< Content-Type: application/json
< Allow: GET, POST, HEAD, OPTIONS
<
[...]

1.5   Throttling

To keep our system stable and healthy, we introduced a throttling mechanism which limits how many HTTP requests any particular client is allowed to make. Current limits are set to the following values:

  • 75 requests per minute per unique PlayerUID in Client access mode
  • 150 requests per minute for an entire account in Developer access mode

Please note: in the Client access mode there is no limit to a number of requests per SDK account. In order to avoid throttling, please make sure to follow these guidelines:

  • Make sure you are not using Developer access mode in production
  • Make sure that every user of your app has a unique PlayerUID associated with it, and that all requests are signed with this PlayerUID. Even if your app or game does not have user accounts, you should still register a unique ID for every client or device. Otherwise, you'll face throttling issues

If an application exceeds limits it will receive HTTP 429 TOO MANY REQUESTS response code and Retry-After HTTP Response Header will be set to the number of seconds application will need to wait to perform next request. See example below:

$ curl -v -H "Authorization: Bearer F88pQWs8hoPzbeCg4xTGifDxxs1eKu" -X GET "https://api.avatarsdk.com/avatars/"
> GET /avatars/ HTTP/1.1
> User-Agent: curl/7.35.0
> Host: api.avatarsdk.com
> Accept: */*
> Authorization: Bearer F88pQWs8hoPzbeCg4xTGifDxxs1eKu
>
< HTTP/1.0 429 TOO MANY REQUESTS
< Date: Mon, 03 Apr 2017 04:08:15 GMT
< Retry-After: 10
< Vary: Accept, Cookie
< Content-Type: application/json
< Allow: GET, POST, HEAD, OPTIONS
<

2   Avatars

2.1   Available pipelines

We are constantly working on our avatars improvements in quality, recognizability and feature set. This way we have released several avatar pipelines. Each avatar pipeline may have pipeline subtype - different set of features available, different model topology, etc. Please find a list of currently available avatar pipelines with their subtypes below:

Source photo
static : deprecated

Static bald head with separate haircuts.

Available subtypes:

  • base/legacy - static bald head with separate haircuts
Model sample
animated_face

Bald head with the optional set of blendshapes for animations (45 facial, 17 visemes) and separate haircuts.

Available subtypes:

  • base/legacy - static bald head with set of blendshapes (45 facial, 17 visemes) for animations and separate haircuts. Default if no subtype specified
  • indie/legacy_styled subtype have different model topology to make available optional mesh modifications (see computation parameters section below)
Model sample
head_1.0 : deprecated

Predicted head, haircut and bust. All-in-one model with unique topology.

Available subtypes:

  • base/static - static predicted head, haircut and bust.
  • base/legacy - predicted head, haircut and bust with set of blendshapes (45 facial, 17 visemes) for animations
  • base/mobile - predicted head, haircut and bust with set of blendshapes (51 facial) for animations
Model samples
head_1.1 : deprecated

Predicted head, haircut and bust. All-in-one model with unique topology. Improved texture and mesh quality (compared to head_1.0).

Available subtypes:

  • base/static - static predicted head, haircut and bust.
  • base/legacy - predicted head, haircut and bust with set of blendshapes (45 facial, 17 visemes) for animations
  • base/mobile - predicted head, haircut and bust with set of blendshapes (51 facial) for animations
Model samples
head_1.2

Predicted head, haircut and bust. All-in-one model with unique topology. Fixed shape and texture artifacts in long hair and busts that are present in head_1.1.

Available subtypes:

  • base/static - static predicted head, haircut and bust
  • base/legacy - predicted head, haircut and bust with set of blendshapes (45 facial, 17 visemes) for animations
  • base/mobile - predicted head, haircut and bust with set of blendshapes (51 facial) for animations
Model samples
head_2.0

Takes the best of head_1.1 and animated_face avatars. Looks exactly like head_1.1, but a hairstyle is represented with a separate mesh (except for bust/static subtype), and a bust can be removed (head/mobile subtype).

Available subtypes:

  • bust/mobile - predicted bust with detachable haircut and set of 51 facial blendshapes
  • bust/static - static predicted bust and haircut
  • head/mobile - predicted head with detachable haircut and set of 51 facial blendshapes. The mesh topology of a head is always the same
Model samples

2.2   Computation Parameters

Avatar computation parameters contain a set of flags and parameters to fine-tune resulting avatar and meta-information about it. These parameters have three levels of details:

  1. The first level is the parameter categories. E.g. set of blendshapes, haircuts, avatar modifications, etc. Please find all available categories with their description in the sections below.
  2. Next level is availability groups. Availability groups may be auto-assigned (e.g. base/common groups or pricing plan dependent groups) and custom (e.g. for custom work). base and public groups are assigned to everyone. Pricing plan dependent groups are indie, plus and pro in the order of priority, starting with least priority. Each next group includes all previous. The facegen group is available starting from the Plus plan.
  3. The last level is parameter types: enumerable and key-value parameters. Avatar computation parameters affect the computation process only if they are specified explicitly. Enumerable parameters are simply listed as JSON array, key-value parameters are specified as JSON object. Value type is parameter dependent. Please see parameter description in the sections below. Please note: all parameters are considered enumerable by default unless stated otherwise.

Please find parameters availability upon your subscription plan for each avatar pipeline in the tables at the end of each category section below. Each cell represents a lower pricing plan. If a cell is empty - it is not available at all.

2.2.1   Haircuts

animated_face pipeline produces bald avatars (i.e. just head, without any haircut). We have three sets of artificial haircuts which are modified during avatar computation process to match each particular avatar head geometry:

base set

3 male and 3 female haircuts

Haircuts samples
facegen set

39 haircuts in total, some of them are unisex

Haircuts samples
plus set

50 haircuts in total, some of them are unisex

Haircuts samples

Availability of these sets depends on your current pricing plan.

For head_2.0 avatars we have additional generated haircut. This haircut is unique and generated for each particular avatar to match haircut from source photo.

It is also possible to add your haircut: contact us at support@avatarsdk.com

Parameters availability

2.2.2   Blendshapes

Avatar SDK supports animated avatars using blendshapes. There are three different blendshapes sets available which should be used depending on your use-case: general animation or lip-sync. Please consult blendshapes set description for more information. Please note that legacy blendshapes set is not recommended to use in the new application as it will be deprecated eventually.

legacy_45
The basic set of 45 facial blendshapes
mobile_51
Set of 51 facial blendshapes. This set is compatible with Apple ARKit: https://developer.apple.com/documentation/arkit/creating_face-based_ar_experiences
visems_17

Set of 15 visemes (aa, ch, ee, ih, oh, ou, th, dd, ff, kk, nn, pp, rr, sil, ss) and two additional blendshapes: frown and smile. This set is compatible with Oculus Lipsync that required these 15 visemes. You can find more details here: https://developer.oculus.com/documentation/audiosdk/latest/concepts/book-audio-ovrlipsync/

The same haircuts meshes are interchangeable between different avatars if the corresponding pointcloud is applied. E.g. you could store mesh from haircut1 of avatar1, then download only pointclouds for haircut1 of avatar2, avatar3 etc. and replace pointcloud in previously-stored mesh. This way you could save customer's network traffic.
