# Telestyle V2 Style Transfer — API Reference

Model ID: `model_telestyle-v2`

---

## Authentication

- **API_KEY** and **API_SECRET** are found in your [Scenario Project Settings](https://app.scenario.com/team&tab=api_keys) under API Keys.
- Set them as environment variables `SCENARIO_SDK_API_KEY` and `SCENARIO_SDK_API_SECRET` — both SDKs pick them up by default.
- For raw HTTP (cURL), use Basic Auth: `Authorization: Basic base64("<API_KEY>:<API_SECRET>")`.

### Install the SDK

- JavaScript / TypeScript: `npm install @scenario-labs/sdk`
- Python: `pip install scenario-sdk`

---

## Generate

**Endpoint:** `POST https://api.cloud.scenario.com/v1/generate/custom/model_telestyle-v2`

### Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `contentImage` | assetId | yes | - | The image you want to restyle. Its subject and composition are kept; only the look changes. |
| `styleImage` | assetId | yes | - | The image whose look you want to borrow — its artistic style, materials, lighting, and colors are applied to your content image. |
| `resolution` | string | - | `square_hd` | The size and shape of the result. |
| `loraScale` | number | - | `1` | How strongly the reference style is applied. Higher values push the styling harder; lower values keep more of the original look. |
| `useLightningLora` | boolean | - | `true` | Adds a speed booster that generates results faster. On by default. |
| `lightningLoraScale` | number | - | `1` | How strongly the speed booster is applied. Only matters when "Use Lightning" is on. |
| `useContentDescription` | boolean | - | `true` | Automatically analyzes your content image and feeds a written description into the process, which can improve how well the subject is preserved. |
| `useStyleDescription` | boolean | - | `true` | Automatically analyzes your style image and feeds a written description into the process, which can improve how well the style is captured. |
| `negativePrompt` | string | - | `` | Things to keep out of the result — for example, "text, watermark, blurry." |
| `numInferenceSteps` | number | - | `4` | How many refinement passes the model makes. More steps can improve quality but take longer. |
| `guidanceScale` | number | - | `1` | How closely the result follows the model's internal prompt. Higher values stick to it more strictly. |
| `acceleration` | string | - | `none` | An optional speed boost. Regular is faster; None prioritizes quality. |
| `numOutputs` | number | - | `1` | How many images to create at once. |
| `seed` | number | - | - | A number that makes results repeatable. Reusing the same seed and settings produces the same image; leave it empty for a different result each time. |

## Retrieve Results

After submitting a generation request, you receive a `jobId`. Poll the job until `job.status` is `"success"`. The generated asset IDs are in `job.metadata.assetIds`.

**Endpoint:** `GET https://api.cloud.scenario.com/v1/jobs/{jobId}`

### Example Requests

**cURL**

```bash
curl -X GET "https://api.cloud.scenario.com/v1/jobs/<JOB_ID>" \
  -H "Authorization: Basic $(echo -n '<API_KEY>:<API_SECRET>' | base64)"
```

**Python**

```python
job = client.jobs.retrieve(job_id="<JOB_ID>")
print(job.status)
print(job.metadata.asset_ids)
```

**JavaScript**

```javascript
// Option 1 — wait on the response from runModel using the SDK helper
const completed = await response.job.wait();
console.info(completed.status);
console.info(completed.metadata?.assetIds);

// Option 2 — retrieve a job by its ID
const job = await client.jobs.retrieve("<JOB_ID>");
console.info(job.status);
console.info(job.metadata?.assetIds);
```

**Example response:**

```json
{
  "job": {
    "jobId": "job_abc123",
    "status": "success",
    "metadata": {
      "assetIds": [
        "asset_abc123"
      ]
    }
  }
}
```

> **Important:** Generated asset URLs are **temporary** and expire after a short period. Download and store any images you wish to keep before the URL expires. More info: [Content Delivery Network (CDN)](https://docs.scenario.com/get-started/documentation/content-delivery-network-cdn).
