# Ideogram V4 Tiling — API Reference

Model ID: `model_ideogram-v4-tiling`

---

## 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_ideogram-v4-tiling`

### Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `prompt` | string | yes | - | Describe the texture or repeating pattern you want. The result is built to repeat seamlessly in the direction you choose. |
| `image` | assetId | - | - | An optional starting image. When provided, it's transformed into a seamless tile instead of generating one from scratch. |
| `strength` | number | - | `0.8` | How much the input image changes. Higher values transform it more; lower values keep it closer to the source. |
| `mask` | assetId | - | - | An optional black-and-white image marking which parts to redo. White areas are regenerated, black areas are kept. Requires an input image. |
| `tilingMode` | string | - | `both` | Which directions the pattern repeats seamlessly. Both repeats in every direction; Horizontal repeats left-to-right; Vertical repeats top-to-bottom. |
| `imageSize` | string | - | `square_hd` | The size and shape of the generated tile. |
| `renderingSpeed` | string | - | `BALANCED` | The tradeoff between speed and quality. Turbo is fastest, Quality is sharpest, and Balanced is a good default. |
| `expansionModel` | string | - | `Medium` | Whether your prompt is automatically enriched with extra detail before generating. None uses your prompt exactly; Medium adds some detail quickly; Large uses Ideogram's Magic Prompt for the richest results. |
| `acceleration` | string | - | `none` | An extra speed boost on top of the rendering setting. Higher values generate faster but may slightly reduce quality. |
| `numOutputs` | number | - | `1` | How many tiles to create from the same prompt. |
| `seed` | number | - | - | A number that makes results repeatable. Reusing the same seed and settings produces the same tile; leave it empty for a different result each time. |

### Example Requests

**cURL**

```bash
curl -X POST "https://api.cloud.scenario.com/v1/generate/custom/model_ideogram-v4-tiling" \
  -H "Authorization: Basic $(echo -n '<API_KEY>:<API_SECRET>' | base64)" \
  -H "Content-Type: application/json" \
  --data-binary @- <<'EOF'
{
  "prompt": "A fantasy landscape",
  "strength": 0.8,
  "tilingMode": "both",
  "imageSize": "square_hd",
  "renderingSpeed": "BALANCED",
  "expansionModel": "Medium",
  "acceleration": "none",
  "numOutputs": 1
}
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 = {
    "prompt": "A fantasy landscape",
    "strength": 0.8,
    "tilingMode": "both",
    "imageSize": "square_hd",
    "renderingSpeed": "BALANCED",
    "expansionModel": "Medium",
    "acceleration": "none",
    "numOutputs": 1
}

response = client.generate.run_model(
    model_id="model_ideogram-v4-tiling",
    body=body,
)
print(response)
```

**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 = {
  "prompt": "A fantasy landscape",
  "strength": 0.8,
  "tilingMode": "both",
  "imageSize": "square_hd",
  "renderingSpeed": "BALANCED",
  "expansionModel": "Medium",
  "acceleration": "none",
  "numOutputs": 1
};

const response = await client.generate.runModel("model_ideogram-v4-tiling", { 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).
