# Creative Upscaler API

> Kreativen, diffusionbaséierten Héichskaléierer, deen Detailer dobäisetzt, mat SD 1.5 oder SDXL als Basis a Formkontroll

Vergréissert e Bild vun `image_url` mat `scale` vun 1 bis 5 a generéiert dobäi nei Detailer. `model_type` ass SD_1_5 oder SDXL, `creativity` an `detail` bestëmmen, wéi staark et geännert gëtt, an `shape_preservation` erhält d’Originalstruktur. Ouni `prompt` gëtt automatesch een erstallt. E personaliséierte Basismodell, LoRA- an Embedding-URLs ginn ënnerstëtzt.

- Model id: `creative-upscaler`
- Made by: Open model
- Category: Upscale
- Output: image
- Charged by usage (up to $1.125 per run, typical $0.007; the rest of the hold is refunded): $0.00125 / second of processing time (cheapest run $0.007 (7 API credits))
- Run: `POST https://api.doitong.com/v1/run/creative-upscaler`
- Quote: `POST https://api.doitong.com/v1/quote/creative-upscaler`
- Docs page: https://doitong.com/lb/developers/models/creative-upscaler

## Pricing

Price: **$0.00125 / second of processing time**. Charged by actual usage at $0.00125 / second of processing time: up to $1.125 per run (the quote gives the maximum for your input), the rest is refunded automatically after the run. A typical run costs $0.007.

The full example input below holds up to $1.125 = 1125 API credits (up to 900 s of processing time × $0.00125) when it starts; a typical run costs $0.007 (7 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). This model is charged by usage: `POST https://api.doitong.com/v1/quote/creative-upscaler` with the same JSON body returns the most the run can cost for that input (`credits`, debited when the run starts); after the run you pay the usage the model reports and the rest is refunded automatically. An input whose maximum would exceed the per-run limit is refused with 422. 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 |
|---|---|---|---|---|---|---|
| `model_type` |  | enum (string) | no | `SD_1_5` | `SD_1_5`, `SDXL` | Modelltyp, dee fir d'Upscaling benotzt gëtt; Standard ass SD_1_5. |
| `image_url` | `image` | string (image URL) | yes |  |  | Quellbild fir d'Upscaling. |
| `prompt` |  | string \| null | no |  |  | Prompt fir d'Bildgeneratioun, dee vu BLIP2 erstallt gëtt, wann Dir en ewechloosst. Wann Dir Ären eegene Prompt liwwert, gitt esou vill beschreiwend Detailer wéi méiglech un, fir déi bescht Resultater ze kréien. |
| `scale` |  | number | no | `2` | 1 – 5 | Erhéicht dëse Skaléierungsfaktor, fir d'Output-Bild méi grouss ze maachen. |
| `creativity` |  | number | no | `0.5` | 0 – 1 | Erlaabten Ofwäichungsgrad vum Original. |
| `detail` |  | number | no | `1` | 0 – 5 | Zousätzlech Detailgrad. |
| `shape_preservation` |  | number | no | `0.25` | 0 – 3 | Grad, an deem d'Form vum Quellbild erhale bleift. |
| `prompt_suffix` |  | string | no | `high quality, highly detailed, high resolution, sharp` |  | Gemeinsamen Enn vum Prompt, fir Embedding-Token oder Formuléierungen ewéi 'high quality' un all Prompts unzehänken. |
| `negative_prompt` |  | string | no | `blurry, low resolution, bad, ugly, low quality, pixelated, interpolated, compression artifacts, noisey, grainy` |  | Negativen Prompt, deen ongewollt Bilddetailer ugëtt. E ka Faarwen, Objeten, Landschaften oder méi fein Detailer a Qualitéiten ausschléissen, ewéi e Moustache, Onschäerft oder niddreg Opléisung. |
| `seed` |  | integer \| null | no |  |  | Seed fir d'Reproduktioun vu Biller a Stable Diffusion. E Bild kann bei all Duerchlaf genee reproduzéiert ginn, wann d'Modellversioun, de Prompt an de Seed onverännert bleiwen. |
| `guidance_scale` |  | number | no | `7.5` | 0 – 16 | Stäerkt vun der Prompt-Entspriechung bei der Bildauswiel, ausgedréckt als CFG (Classifier Free Guidance). |
| `num_inference_steps` |  | integer | no | `20` | 1 – 200 | Unzuel vun den Inferenz-Schrëtt fir d'Bildgeneratioun; méi Schrëtt verbesseren d'Bildqualitéit, verlängeren awer d'Generatiounszäit. |
| `enable_safety_checks` |  | boolean | no | `true` |  | Sécherheetskontroll-Optioun, déi bei true e schwaarzt Bild amplaz vun all Resultat setzt, dat als potenziell onsécheren Inhalt erkannt gëtt. |
| `skip_ccsr` |  | boolean | no | `false` |  | Iwwersprange vun der CCSR-Virveraarbechtung wann aktivéiert; d'Bild geet amplaz direkt an de Kreativitéitsmodell. |
| `override_size_limits` |  | boolean | no | `false` |  | Erlaabnis fir grouss Uploads, déi ganz laang dauere kënnen. |
| `base_model_url` |  | string \| null | no |  |  | URL vum Basismodell fir d'Upscaling. |
| `additional_lora_url` |  | string | no |  |  | Gitt eng zousätzlech LORA fir d'Upscaling un, andeems Dir hir Modell-URL liwwert. Ouni Wäert ass de Standard None. |
| `additional_lora_scale` |  | number | no | `1` |  | Passt un, wéi staark déi zousätzlech LORA d'Upscaling beaflosst, iwwer hir Skala-Astellung, déi standardméisseg op 1.0 steet. |
| `additional_embedding_url` |  | string | no |  |  | Gitt zousätzlech Embeddings fir d'Upscaling un, andeems Dir iwwer eng URL op si weist. Ouni Wäert ass de Standard None. |

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`.

## 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/creative-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/creative-upscaler?wait=20", {

});
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();

### 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/creative-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": "creative-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.
