## Usage Examples

### cURL

```bash
curl --request POST \
  --url https://fal.run/minimax/h3-max/styles/retro-toon-70s \

```

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(
    "minimax/h3-max/styles/retro-toon-70s",
    arguments={
        "prompt": "A lone warrior with a broadsword stands on a windswept rocky ridge at sunset as an enormous dragon glides past below him. Wide heroic shot. Wind and the slow beat of dragon wings, no speech."
    },
    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("minimax/h3-max/styles/retro-toon-70s", {
  input: {
    prompt: "A lone warrior with a broadsword stands on a windswept rocky ridge at sunset as an enormous dragon glides past below him. Wide heroic shot. Wind and the slow beat of dragon wings, no speech."
  },
  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);
```
