- **`draft_cache_url`** (`string`, _required_):
  URL or data URI of the encrypted draft cache bundle to enhance.

- **`safety_tolerance`** (`integer`, _optional_):
  The safety tolerance level for the generated video. 0 is the strictest and 4 is the most permissive. Default value: `2`
  - Default: `2`
  - Range: `0` to `4`



**Required Parameters Example**:

```json
{
  "draft_cache_url": ""
}
```

**Full Example**:

```json
{
  "draft_cache_url": "",
  "safety_tolerance": 2
}
```


### Output Schema

The API returns the following output format:

- **`video`** (`File`, _required_):
  The enhanced video.



**Example Response**:

```json
{
  "video": {
    "url": "",
    "content_type": "image/png",
    "file_name": "z9RV14K95DvU.png",
    "file_size": 4404019
  }
}
```


## Usage Examples

### cURL

```bash
curl --request POST \
  --url https://fal.run/blackforestlabs/flux-3/draft-enhance \
  --header "Authorization: Key $FAL_KEY" \
  --header "Content-Type: application/json" \
  --data '{
     "draft_cache_url": ""
   }'
```

### 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(
    "blackforestlabs/flux-3/draft-enhance",
    arguments={
        "draft_cache_url": ""
    },
    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("blackforestlabs/flux-3/draft-enhance", {
  input: {
    draft_cache_url: ""
  },
  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);
```
