# 🖼️ Text-to-Image Generator API (lucataco DreamShaper XL Turbo)

## Overview
DreamShaper XL Turbo is a general-purpose Stable Diffusion model. Its developer describes it as aiming to do everything well: photos, art, anime and manga.

Send a text `prompt` to generate images. Each request returns a list of 1 to 4 image URLs (`num_outputs`).

## Features
- **Few steps**: `num_inference_steps` defaults to 6 (1 to 50).
- **Several images per request**: `num_outputs` from 1 to 4.
- **Size**: set `width` and `height` in pixels (default 1024 x 1024).
- **Schedulers**: `DDIM`, `DPMSolverMultistep`, `HeunDiscrete`, `KarrasDPM`, `K_EULER_ANCESTRAL`, `K_EULER` (default) and `PNDM`.
- **Prompt control**: `negative_prompt`, `guidance_scale` (1 to 20) and `seed`.
- **Watermark**: `apply_watermark` (default `true`) marks images as generated.

## Use Cases
1. **Illustrations and concept art**: painted, anime or manga-style images from a prompt.
2. **Photo-style images**: portraits, products and scenes.
3. **Variations**: up to 4 images per request with `num_outputs`.

## Visual Examples
### Example Input
The example generates one 1024 x 1024 digital painting of a futuristic explorer in gold filigree armor, using 7 steps and the `K_EULER` scheduler.

```json
{
  "width": 1024,
  "height": 1024,
  "prompt": "Portrait of a futuristic explorer with long brown hair and ornate gold filigree armor, cinematic side lighting, highly detailed digital painting",
  "scheduler": "K_EULER",
  "num_outputs": 1,
  "guidance_scale": 2,
  "apply_watermark": true,
  "negative_prompt": "ugly, deformed, noisy, blurry, low contrast, text, BadDream, 3d, cgi, render, fake, anime, open mouth, big forehead, long neck",
  "num_inference_steps": 7
}
```

### Example Output
![DreamShaper XL Turbo output: a painted portrait of a futuristic explorer with long brown hair and gold filigree armor](https://blog.api.market/wp-content/uploads/2026/10/dreamshaper-xl-turbo-output-0epcew2a-api-market.jpg)

## Input Parameters
| Field | Type | Required | Default | Allowed values | Description |

| `negative_prompt` | string | No | `""` |  | Input negative prompt. |
| `width` | integer | No | `1024` |  | Width of the output image in pixels. |
| `height` | integer | No | `1024` |  | Height of the output image in pixels. |
| `num_outputs` | integer | No | `1` | 1 to 4 | Number of images to output. |
| `scheduler` | string | No | `K_EULER` | `DDIM`, `DPMSolverMultistep`, `HeunDiscrete`, `KarrasDPM`, `K_EULER_ANCESTRAL`, `K_EULER`, `PNDM` | Scheduler. |

| `seed` | integer | No | none |  | Random seed. Leave blank to randomize the seed. |
| `apply_watermark` | boolean | No | `true` |  | Applies a watermark so generated images can be identified later. If you have other provisions for generating or deploying images safely, you can use this to disable watermarking. |
| `disable_safety_checker` | boolean | No | `false` |  | Disable the safety checker for generated images. |

## Pricing
- **Pay As You Go (PAYG) pricing**: you only pay for what you use.
- **Price**: $0.017 per API unit.
- **1 API unit = 1 successful request** that uses up to 15 seconds of processing time. A request that needs more processing time is billed one more unit for each started block of 15 seconds (for example, 16 to 30 seconds of processing is 2 units, $0.034).
- A request costs the same whether it returns 1 or 4 images, as long as it finishes within 15 seconds of processing.
- **Example cost**: the example request on this page used 1.9 seconds of processing, so it was billed 1 unit ($0.017).
- **Failed or cancelled predictions are not billed.**
- **GET requests to check prediction status** are free and don't count toward API unit usage.
- **No monthly subscription fee.**

## API Documentation

### Base URL
All API requests go to: `https://prod.api.market/api/v1/magicapi/text-to-image-generator-ai-lucataco-dreamshaper-xl-turbo`

### Authentication
Send your api.market API key in the `x-api-market-key` header:
```
x-api-market-key: YOUR_API_MARKET_KEY
```

### Asynchronous Processing
**IMPORTANT**: This API is asynchronous. The flow is:
1. Send a POST request to `/predictions`. A successful request returns **201 Created** with a prediction `id` and a `status` of `starting` or `processing`.
2. Poll GET `/predictions/{id}` with that ID.
3. Keep polling while `status` is `starting` or `processing`.
4. Stop when `status` is `succeeded` (read `output`), `failed` or `canceled` (read `error`).

A polling interval of 1 second and an overall timeout of 600 seconds (10 minutes) work well.

### Endpoints

#### Create a Prediction
```bash
curl -X POST "https://prod.api.market/api/v1/magicapi/text-to-image-generator-ai-lucataco-dreamshaper-xl-turbo/predictions" \
  -H "Content-Type: application/json" \
  -H "x-api-market-key: YOUR_API_MARKET_KEY" \
  -d '{
    "version": "0a1710e0187b01a255302738ca0158ff02a22f4638679533e111082f9dd1b615",
    "input": {
      "width": 1024,
      "height": 1024,
      "prompt": "Portrait of a futuristic explorer with long brown hair and ornate gold filigree armor, cinematic side lighting, highly detailed digital painting",
      "scheduler": "K_EULER",
      "num_outputs": 1,
      "guidance_scale": 2,
      "apply_watermark": true,
      "negative_prompt": "ugly, deformed, noisy, blurry, low contrast, text, BadDream, 3d, cgi, render, fake, anime, open mouth, big forehead, long neck",
      "num_inference_steps": 7
    }
  }'
```

Response (201 Created):
```json
{
  "id": "0epcew2ag1rmr0d1d2096m68qc",
  "version": "0a1710e0187b01a255302738ca0158ff02a22f4638679533e111082f9dd1b615",
  "status": "starting",
  "created_at": "2026-10-23T11:23:20.757Z"
}
```

#### Check Prediction Status
```bash
curl -X GET "https://prod.api.market/api/v1/magicapi/text-to-image-generator-ai-lucataco-dreamshaper-xl-turbo/predictions/{id}" \
  -H "x-api-market-key: YOUR_API_MARKET_KEY"
```

Response when the prediction has finished (200 OK):
```json
{
  "id": "0epcew2ag1rmr0d1d2096m68qc",
  "status": "succeeded",
  "output": [
    "https://blog.api.market/wp-content/uploads/2026/10/dreamshaper-xl-turbo-output-0epcew2a-api-market.jpg"
  ],
  "error": null,
  "created_at": "2026-10-23T11:23:20.757Z",
  "started_at": "2026-10-23T11:24:54.651Z",
  "completed_at": "2026-10-23T11:24:56.597Z"
}
```

`output` is a list of image URLs, one per generated image (`num_outputs`).

### Status Codes
- **201 Created**: prediction created (POST `/predictions`). This is the normal success response.
- **200 OK**: prediction details returned (GET `/predictions/{id}`).
- **400 Bad Request**: invalid input, for example a `num_outputs` above 4 or a `scheduler` that is not in the list.
- **401 Unauthorized**: missing or invalid API key.
- **404 Not Found**: no prediction with that ID.
- **429 Too Many Requests**: rate limit exceeded.
- **500 Internal Server Error** or **503 Service Unavailable**: temporary server problem; retry later.

## Rate Limits
All plans allow 10 requests per second. Requests above that return `429 Too Many Requests`; back off before retrying and honour any `Retry-After` header. Polling a prediction with GET is free but still counts toward the per-second limit, so poll every 1 to 5 seconds rather than in a tight loop.

## Error Handling
- Check the HTTP status code of every request and read the response body for the error message.
- A prediction can also end with `status` set to `failed`; the `error` field then explains why. Failed predictions are not billed.
- Retry 429, 500 and 503 responses with exponential backoff. Fix the input before retrying a 400.

## FAQ
- **How many images does one request return?**
  - `num_outputs` images, from 1 to 4. The default is 1.
- **How many steps should I use?**
  - The default is 6 and the example used 7. Start with the default and raise `num_inference_steps` (up to 50) if you need more detail.
- **Can I turn off the watermark?**
  - Yes. Set `apply_watermark` to `false` if you handle labeling of generated images another way.
- **Is the 201 response from POST an error?**
  - No. 201 Created means the prediction was accepted. Use the returned `id` to poll GET `/predictions/{id}` until `status` is `succeeded`, `failed` or `canceled`.
- **What if my prediction fails?**
  - Failed predictions are not billed. Read the `error` field, adjust the input and try again.
