# YVO3D Retexture — API Reference

Model ID: `model_yvo3d-retexture`

---

## 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_yvo3d-retexture`

### Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `model` | assetId | yes | - | The existing GLB 3D model you want to give a new surface. |
| `retexture` | boolean | - | `false` | On, the model's existing surface is replaced with newly generated textures (a reference image is required). Off, the current textures are kept. |
| `referenceImage` | assetId | - | - | An image to guide the look of the new textures — color, material, and style. Required when Replace Textures is on. |
| `textureResolution` | string | - | `1K` | The detail level of the generated texture. Higher resolutions look sharper but cost more. |
| `realismLevel` | number | - | `0.85` | How photorealistic the texture looks. Higher values are more realistic. |
| `creativity` | number | - | `3` | How much creative freedom the model takes. 0 stays faithful to your reference; 5 allows more imaginative interpretation. |
| `generateUvs` | string | - | `ON` | Automatically creates UV maps — the layout that lets a texture wrap correctly onto the 3D surface — when they're missing. |
| `hyperMode` | string | - | `OFF` | Processes textures faster and at lower cost, with a small drop in quality. |
| `insideOut` | string | - | `OFF` | Textures the inside surfaces of the model as well as the outside, rather than just the outside. Adds cost. |
| `unlit` | string | - | `OFF` | Bakes the texture without any lighting or shadows, so the model looks the same under any lighting in your scene. |
| `textureSharpness` | number | - | `0.5` | How sharp and detailed the texture appears. Higher values enhance fine detail. |
| `textureAdherence` | string | - | `OFF` | When on, keeps the generated texture closer to the look of your reference image. |
| `roughness` | number | - | `1.3` | How matte or glossy the surface looks. Higher values are more matte; lower values are shinier. |

## 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).
