# Meshy Text-to-3D — API Reference

Model ID: `model_meshy-txt23d`

---

## 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_meshy-txt23d`

### Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `aiModel` | string | - | `latest` | Meshy model to use. |
| `prompt` | string | yes | - | Describe the object you want to generate as a 3D model. |
| `texturePrompt` | string | - | `` | Provide a text description to guide the texturing process. The Style Prompt is only used when no Style Image is provided. If you upload an image, this text prompt will be ignored. |
| `textureImage` | assetId | - | - | Upload a reference image to guide the visual style of the generated texture. This will override the Style Prompt. |
| `artStyle` | string | - | `realistic` | Describe your desired art style of the object. Note that 'Enable PBR'' should be set to false when using Art style. |
| `topology` | string | - | `triangle` | Choose the mesh structure type used for the generated model (e.g., triangles or quads). |
| `enablePbr` | boolean | - | `true` | Generate advanced PBR maps (metallic, roughness, normal) for more realistic materials. |
| `poseMode` | string | - | `` | Specify the pose mode for the generated model. Accepts 'a-pose', 't-pose', or empty string (default). |
| `shouldRemesh` | boolean | - | `false` | Enable remeshing to improve mesh quality and control polycount. Disable to keep the raw, unprocessed mesh. |
| `symmetryMode` | string | - | `auto` | Control how symmetry is applied during model generation for balanced, even shapes. |
| `targetPolycount` | number | - | `30000` | Specify the target number of polygons in the generated model. The actual number of polygons may deviate from the target depending on the complexity of the geometry. |
| `seed` | number | - | - | Seed for random number generator. If None, a random seed will be used. |

}
EOF
```

**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 = {
    "aiModel": "latest",
    "prompt": "A fantasy landscape",
    "texturePrompt": "",
    "artStyle": "realistic",
    "topology": "triangle",
    "enablePbr": True,

**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 = {

};

const response = await client.generate.runModel("model_meshy-txt23d", { body });
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).
