# 🎨 Photo-to-Anime Style Transfer API (Qwen Image Edit Plus LoRA)

## Overview
Photo to Anime is an image editing model built on Qwen-Image-Edit-Plus with a Photo-to-Anime LoRA adapter. Its developer describes it as a stylized conversion that turns photos into crisp cel-shaded anime frames.

Send a photo as `image`. The `prompt` already defaults to an anime conversion instruction, so `image` is the only required field; add style cues to the prompt to steer the result. Each request returns a list with the URL of one image.

## Features
- **Photo to anime**: converts a photo into an anime-style frame with line art and cel-shaded colors.
- **Prompt style cues**: start the prompt with `transform into anime` and add cues such as cel shading, energetic lighting or manga line work. The default prompt is `transform into anime, clean line art, vibrant cel-shaded colors`.
- **Aspect ratio**: `match_input_image` (default) keeps the shape of your photo; you can also choose `1:1`, `16:9`, `9:16`, `4:3` or `3:4`.
- **Speed or detail**: `go_fast` set to `true` runs an 8-step preset, `false` runs a 40-step preset. Set `num_inference_steps` (1 to 40) to choose the step count yourself.
- **LoRA controls**: `lora_scale` (0 to 4) sets the strength of the anime adapter; `lora_weights` swaps in different LoRA weights.
- **Guidance**: `true_guidance_scale` (0 to 10, default 1).
- **Output format**: `webp` (default), `jpg` or `png`, with `output_quality` from 0 to 100 for lossy formats.
- **Seed**: set `seed` to reproduce a result.

## Use Cases
1. **Anime avatars and profile pictures**: turn a portrait photo into an anime-style character.
2. **Fan art and illustration drafts**: convert reference photos into cel-shaded frames as a starting point.
3. **Social content**: anime versions of photos for posts, stickers and thumbnails.
4. **App features**: add a "turn me into anime" filter to a photo or camera app.

## Visual Examples
### Example Input
Input image:

![Example input: a portrait photo of a person](https://blog.api.market/wp-content/uploads/2026/10/p-video-avatar-input-api-market.webp)

Prompt: "transform into anime, clean line art, vibrant cel-shaded colors, soft pastel background"

All other fields were left at their defaults (`match_input_image`, `webp`).

### Example Output
![Photo to Anime output: the input portrait converted to an anime-style image](https://blog.api.market/wp-content/uploads/2026/10/qwen-image-edit-plus-lora-photo-to-anime-output-api-market.webp)

| `disable_safety_checker` | boolean | No | `false` |  | Disable safety checker for generated images. |

## Pricing
- **Pay As You Go (PAYG) pricing**: you only pay for what you use.
- **Price**: $0.038 per API unit.
- **1 API unit = 1 output image.** Each request returns one image, so each successful request costs $0.038.
- Every input setting (aspect ratio, step count, output format) is billed the same. The example request above cost $0.038.
- **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/photo-to-anime-style-transfer-qwen-edit-apps-qwen-image-edit-plus-lora-photo-to-anime`

### 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/photo-to-anime-style-transfer-qwen-edit-apps-qwen-image-edit-plus-lora-photo-to-anime/predictions" \
  -H "Content-Type: application/json" \
  -H "x-api-market-key: YOUR_API_MARKET_KEY" \
  -d '{
    "version": "bc101c8a367f975c528267a275ef0b25574966fdfd73ba17f0ff8c3f570cfea6",
    "input": {
      "image": "https://blog.api.market/wp-content/uploads/2026/10/p-video-avatar-input-api-market.webp",
      "prompt": "transform into anime, clean line art, vibrant cel-shaded colors, soft pastel background"
    }
  }'
```

Response (201 Created):
```json
{
  "id": "2eqenm100srmt0d17fta97b1g4",
  "version": "bc101c8a367f975c528267a275ef0b25574966fdfd73ba17f0ff8c3f570cfea6",
  "status": "starting",
  "created_at": "2026-10-14T19:46:57.272Z"
}
```

#### Check Prediction Status
```bash
curl -X GET "https://prod.api.market/api/v1/magicapi/photo-to-anime-style-transfer-qwen-edit-apps-qwen-image-edit-plus-lora-photo-to-anime/predictions/{id}" \
  -H "x-api-market-key: YOUR_API_MARKET_KEY"
```

Response when the prediction has finished (200 OK):
```json
{
  "id": "2eqenm100srmt0d17fta97b1g4",
  "status": "succeeded",
  "output": [
    "https://blog.api.market/wp-content/uploads/2026/10/qwen-image-edit-plus-lora-photo-to-anime-output-api-market.webp"
  ],
  "error": null,
  "created_at": "2026-10-14T19:46:57.272Z",
  "started_at": "2026-10-14T19:46:58.272Z",
  "completed_at": "2026-10-14T19:47:09.272Z"
}
```

`output` is a list of URL strings. It holds one generated image, in the format set by `output_format`.

### 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 missing `image` or a `num_inference_steps` outside 1 to 40.
- **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, for example when `image` cannot be downloaded. Failed predictions are not billed.
- Retry 429, 500 and 503 responses with exponential backoff. Fix the input before retrying a 400.

## FAQ
- **Do I need to write a prompt?**
  - No. `image` is the only required field. The default prompt is `transform into anime, clean line art, vibrant cel-shaded colors`. Write your own prompt starting with `transform into anime` to add style cues or describe the background.
- **How do I trade speed for detail?**
  - Leave `num_inference_steps` empty and set `go_fast` to `true` for the 8-step preset or `false` for the 40-step preset. Or set `num_inference_steps` (1 to 40) yourself.
- **The anime effect is too weak or too strong. What can I change?**
  - Adjust `lora_scale` (0 to 4), which sets the strength of the anime adapter. Leave it empty for the default strength.
- **Will the output keep the shape of my photo?**
  - Yes, by default. `aspect_ratio` is `match_input_image` unless you choose `1:1`, `16:9`, `9:16`, `4:3` or `3:4`.
- **How many images does one request return, and what does it cost?**
  - One image, returned as a one-item list in `output`. It costs $0.038.
- **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`.
