## tripo-rig API Guide

### About
tripo auto rigging for 3d models. bipeds, quadrupeds and other creatures, mixamo, unity, unreal or vrm bone naming, and up to five preset animations. glb or fbx out.

### Get an API Key
Create one in [settings → api keys](https://app.inference.sh/settings/keys). The examples read it from `INFERENCE_API_KEY`.

```bash
export INFERENCE_API_KEY="inf_your_key"
```

### 1. Calling the API

#### Install the Client

```bash
pip install inferencesh
```

#### Run and Get Result
Submit a request and wait for the final result.

```python
import os
from inferencesh import inference

client = inference(api_key=os.environ["INFERENCE_API_KEY"])

## version @6072e4td pinned
result = client.run({
        "app": "tripo/tripo-rig@6072e4td",
        "input": {
            "model": "https://example.com/file.png"
        }
    })

print(result["output"])
```

#### Stream Live Updates
Get real-time progress updates as the task runs.

```python
import os
from inferencesh import inference

client = inference(api_key=os.environ["INFERENCE_API_KEY"])

## version @6072e4td pinned
## stream=True yields updates as they arrive
for update in client.run({
        "app": "tripo/tripo-rig@6072e4td",
        "input": {
            "model": "https://example.com/file.png"
        }
    }, stream=True):
    if update.get("progress"):
        print(f"progress: {update['progress']}%")
    if update.get("output"):
        print(f"output: {update['output']}")
```

#### Run in the Background
Start the task and get its id back right away, then check on it with `GET /tasks/{id}`. It is done when `status` is 10 (completed), 11 (failed) or 12 (cancelled).

```python
import os
from inferencesh import inference, TaskStatus

client = inference(api_key=os.environ["INFERENCE_API_KEY"])

## returns as soon as the task is created
task = client.run({
        "app": "tripo/tripo-rig@6072e4td",
        "input": {
            "model": "https://example.com/file.png"
        }
    }, wait=False)

## later: read its current state
state = client.tasks.get(task["id"]).data
if state["status"] == TaskStatus.COMPLETED:
    print(state["output"])
```

### 2. Files

#### Automatic Upload

```python
## local file paths are automatically uploaded
result = client.run({
    "app": "tripo/tripo-rig@6072e4td",
    "input": {
        "image": "/path/to/local/image.png",  # detected & uploaded
        "audio": "https://example.com/audio.mp3",  # url passed through
    }
})
```

#### Manual Upload

```python
## upload and get a hosted URL
file = client.files.upload("/path/to/file.png")
print(file.uri)  # https://cloud.inference.sh/...
```

### 3. Schema

#### Input
- **model** (string) *required*: The 3D model to rig: GLB, FBX, OBJ or STL, up to 150 MB.
- **rig_type** (string): The kind of body. Empty: Tripo's rig check decides, and refuses a model it cannot rig.
- **spec** (string): Bone naming for a biped: Tripo's own, or that of Mixamo, ActorCore, Unity, Unreal or VRM.
- **out_format** (string): File format of the rigged model.
- **animations** (array): Preset animations to put on the rig, up to five (10 credits each). Plain presets are for bipeds; the others name their rig type.
- **animate_in_place** (boolean): Keep animations in place instead of moving through the scene.

#### Output
- **animated** (string): The rigged model with the animations, when any were asked for.
- **model** (string): The rigged model.
- **rig_type** (string): The rig type used.
