  - Default: `1.7`

- **`enable_animation`** (`boolean`, _optional_):
  Apply an animation preset to the rigged model.
  - Default: `false`

- **`animation_action_id`** (`integer`, _optional_):
  Animation preset ID from Meshy's library (500+ presets). Only used when enable_animation is true. See https://docs.meshy.ai/en/api/animation-library for available action IDs. Default value: `1001`
  - Default: `1001`
  - Examples: 1001

- **`enable_safety_checker`** (`boolean`, _optional_):
  If set to true, input data will be checked for safety before processing. Default value: `true`
  - Default: `true`

## Usage Examples

### cURL

```bash
curl --request POST \
  --url https://fal.run/fal-ai/meshy/rigging \
  --header "Authorization: Key $FAL_KEY" \
  --header "Content-Type: application/json" \
  --data '{
     "model_url": "https://storage.googleapis.com/falserverless/model_tests/video_models/base_basic_shaded.glb"
   }'
```

### Python

Ensure you have the Python client installed:

```bash
pip install fal-client
```

Then use the API client to make requests:

```python
import fal_client

def on_queue_update(update):
    if isinstance(update, fal_client.InProgress):
        for log in update.logs:
           print(log["message"])

result = fal_client.subscribe(
    "fal-ai/meshy/rigging",
    arguments={
        "model_url": "https://storage.googleapis.com/falserverless/model_tests/video_models/base_basic_shaded.glb"
    },
    with_logs=True,
    on_queue_update=on_queue_update,
)
print(result)
```

### JavaScript

Ensure you have the JavaScript client installed:

```bash
npm install --save @fal-ai/client
```

Then use the API client to make requests:

```javascript
import { fal } from "@fal-ai/client";

const result = await fal.subscribe("fal-ai/meshy/rigging", {
  input: {
    model_url: "https://storage.googleapis.com/falserverless/model_tests/video_models/base_basic_shaded.glb"
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
      update.logs.map((log) => log.message).forEach(console.log);
    }
  },
});
console.log(result.data);
console.log(result.requestId);
```
