# Tripo 3.1 — API Reference

Model ID: `model_tripo-v3-1-image-to-3d`

---

## Authentication

- **API_KEY** and **API_SECRET** are found in your [Scenario Project Settings](https://app.scenario.com/team&tab=project_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_tripo-v3-1-image-to-3d`

### Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `image` | assetId | yes | - | Single image for image-to-model. |
| `texture` | boolean | - | `true` | Enable texturing. Set to false for a model without textures. |
| `textureQuality` | string | - | `standard` | Texture quality level. 'Detailed' gives HD quality textures. |
| `textureAlignment` | string | - | `original_image` | Determines the prioritization of texture alignment in the 3D model. |
| `geometryQuality` | string | - | `standard` | Geometry quality level. 'Detailed' gives HD quality geometry. |
| `textureSeed` | number | - | - | Random seed for texture generation. Using the same seed will produce identical textures. |
| `orientation` | string | - | `default` | Set orientation to 'Align Image' will automatically rotate the model to align the original image. |
| `pbr` | boolean | - | `true` | Enable PBR generation. Default value is True. If this option is set to True, texture parameters will be ignored. |
| `faceLimit` | number | - | - | Limits the number of faces on the output model. If this option is not set, the face limit will be adaptively determined. |
| `autoSize` | boolean | - | `false` | Automatically scale the model to real-world dimensions, with the unit in meters. |
| `quad` | boolean | - | `false` | Set True to enable quad mesh output. |
| `smartLowPoly` | boolean | - | `false` | Generate hand-crafted low-poly topology. |
| `generateParts` | boolean | - | `false` | Generate segmented 3D model parts. Incompatible with texture, pbr, and quad. |
| `seed` | number | - | - | Random seed for model generation. The seed controls the geometry generation process, ensuring identical models when the same seed is used. |

```

**Python**

```python
import os
from scenario_sdk import Scenario

client = Scenario(
    api_key=os.environ.get("SCENARIO_SDK_API_KEY"),
    api_secret=os.environ.get("SCENARIO_SDK_API_SECRET"),
)

body = {
    "image": "<asset_id>",
    "texture": True,
    "textureQuality": "standard",
    "textureAlignment": "original_image",
    "geometryQuality": "standard",

**JavaScript**

```javascript
import Scenario from "@scenario-labs/sdk";

const client = new Scenario({
  apiKey: process.env["SCENARIO_SDK_API_KEY"],
  apiSecret: process.env["SCENARIO_SDK_API_SECRET"],
});

const body = {
  "image": "<asset_id>",
  "texture": true,

console.info(response);
```

## 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).
