Developer API

Use the AutoRig HTTP API to create tasks from a link or an upload, poll until the task is done, then download the rigged model, animation files and related files via stable URLs. A task is the same V3 task as on the site, and its result is the V3 viewer with animation clips and exports.

Base URL: https://autorig.online

How a task works in V3

A task starts from any input: a 3D model (GLB, FBX, OBJ or a ZIP with textures), a picture, a picture of a car, or text. The calls below create a task from a link or an upload; the examples use a model link.
The V3 conveyor builds the skeleton and skin from the geometry in seconds and retargets the animation clips at once. Quality checks run in the background.
The result is the task page https://autorig.online/task?id=TASK_ID: the V3 viewer with the clips and the AI agent chat.
The viewer offers GLB, FBX, USDZ, ZIP, Unity package and Blender downloads. The endpoints below have stable URLs, and cached-files lists every file the task has with its download URL.

Authentication

Send your secret key on every request using either header: Authorization: Bearer <key> or X-API-Key: <key>. Keys look like ar_<prefix>_<secret>. Signed-in users and anonymous visitors (with a browser session cookie) can create keys from this page or Buy credits.

API Access

Generate an API key to use AutoRig REST API from external tools.

Main endpoints

Method	Path	Notes
POST	`/api/task/create`	multipart form: source=link, input_url, type=t_pose
GET	`/api/task/{id}`	Task status and metadata
GET	`/api/task/{id}/prepared.glb`	Preview / prepared model GLB
GET	`/api/task/{id}/animations.glb`	Combined animations GLB
GET	`/api/task/{id}/animations.fbx`	Animations FBX (Unity etc.)
GET	`/api/task/{id}/model.glb`	Base model GLB
GET	`/api/task/{id}/cached-files`	JSON list of cached files and download URLs

Typical flow

POST /api/task/create with a link (JSON with input_url, or multipart with input_url or a file).
GET /api/task/{id} until the status is done or error.
GET /api/task/{id}/cached-files for the list of files.
Download with GET on prepared.glb, animations.glb, animations.fbx or model.glb.

Examples

Replace TASK_ID and YOUR_API_KEY. For link-based input, use a publicly reachable URL to your GLB/FBX/OBJ.

curl -X POST "$BASE/api/task/create" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"input_url":"https://example.com/model.glb"}'

curl -X POST "$BASE/api/task/create" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "input_url=https://example.com/model.glb"

curl -H "Authorization: Bearer YOUR_API_KEY" "$BASE/api/task/TASK_ID"

curl -o out.glb -H "Authorization: Bearer YOUR_API_KEY" "$BASE/api/task/TASK_ID/prepared.glb"

U3D YouTube provider

U3D uploads use a dedicated provider key and isolated OAuth credentials. An AutoRig admin API key is neither required nor accepted. Open the provider page for the ready curl example, live readiness status, admin-only key copy button, and agent skill.
