# Chrono Edit Lora Gallery · Upscaler API

> بزرگ‌نمایی و پاک‌سازی تصویر با ضریب 1x تا 4x، مبتنی بر تنظیمات Chrono Edit LoRA

تصویر را بدون نیاز به پرامپت بزرگ‌نمایی و پاک‌سازی می‌کند. `upscale_factor` از 1 تا 4 است و پیش‌فرض آن 2 است. `num_inference_steps` از 2 تا 50 و پیش‌فرض آن 30 است و `lora_scale` از 0 تا 2 تغییر می‌کند. خروجی می‌تواند jpeg، png یا webp باشد و حداکثر 3 LoRA اضافی قابل ادغام است.

- Model id: `chrono-edit-lora-gallery/upscaler`
- Made by: NVIDIA
- Category: Upscale
- Output: image
- Price: $0.03 / image (cheapest run $0.03 (30 API credits))
- Run: `POST https://api.doitong.com/v1/run/chrono-edit-lora-gallery/upscaler`
- Quote: `POST https://api.doitong.com/v1/quote/chrono-edit-lora-gallery/upscaler`
- Docs page: https://doitong.com/fa/developers/models/chrono-edit-lora-gallery/upscaler

## Pricing

Price: **$0.03 / image**. Billed per generated image.

The full example input below costs $0.03 = 30 API credits (1 image × 30 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/chrono-edit-lora-gallery/upscaler` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `image_url` | `image` | string (image URL) | yes |  |  | تصویر منبع برای ارتقای وضوح. |
| `upscale_factor` |  | number | no | `2` | 1 – 4 | ضریب وضوح مطلوب برای خروجی. |
| `guidance_scale` |  | number | no | `1` | 0 – 10 | مقیاس راهنمایی اعمال‌شده هنگام استنتاج. |
| `enable_safety_checker` |  | boolean | no | `true` |  | کلید بررسی ایمنی که حالت خاموش آن فقط برای حساب‌های مجاز پذیرفته می‌شود. همه درخواست‌های فاقد این مجوز بررسی ایمنی می‌شوند. |
| `num_inference_steps` |  | integer | no | `30` | 2 – 50 | تعداد تکرارهای استنتاج هنگام ارتقای وضوح. |
| `lora_scale` |  | number | no | `1` | 0 – 2 | ضریب مقیاس‌گذاری اعمال‌شده به آداپتور LoRA. |
| `seed` |  | integer \| null | no |  |  | seed استفاده‌شده هنگام استنتاج. |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png`, `webp` | قالب فایل تصویر حاصل. |
| `loras` |  | array of object {path, scale} | no | `[]` |  | مجموعه اختیاری LoRAهای اضافی برای ادغام، حداکثر 3 مورد. |
| `loras[].path` |  | string | yes |  |  | محل وزن‌های LoRA در قالب Safetensors که به‌صورت URL یا مسیر مشخص می‌شود. |
| `loras[].scale` |  | number | no | `1` | 0 – 4 | ضریب مقیاس‌گذاری که قدرت LoRA را تعیین می‌کند. |

File parameters (`image`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/chrono-edit-lora-gallery/upscaler?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/chrono-edit-lora-gallery/upscaler?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/chrono-edit-lora-gallery/upscaler", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "chrono-edit-lora-gallery/upscaler",
      "input": {
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
