# Creative Upscaler API

> Skapandi stækkari byggður á dreifingu sem bætir við smáatriðum, með SD 1.5 eða SDXL-grunni og stýringu á lögun

Stækkar mynd frá `image_url` um `scale` 1 til 5 og myndar um leið ný smáatriði. `model_type` er SD_1_5 eða SDXL, `creativity` og `detail` stilla hversu miklu er breytt og `shape_preservation` varðveitir upprunalega byggingu. Án `prompt` er hann myndaður sjálfkrafa. Stuðningur er við sérsniðin grunnmódel, LoRA og embedding-slóðir.

- 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.ru/v1/run/creative-upscaler`
- Quote: `POST https://api.doitong.ru/v1/quote/creative-upscaler`
- Docs page: https://doitong.com/is/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.ru/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` | Líkangerð sem notuð er við stækkun; sjálfgefið er SD_1_5. |
| `image_url` | `image` | string (image URL) | yes |  |  | Upprunamynd fyrir stækkun. |
| `prompt` |  | string \| null | no |  |  | Kvaðning fyrir myndgerð, búin til af BLIP2 þegar þú sleppir henni. Þegar þú gefur upp eigin kvaðningu skaltu hafa eins ítarlega lýsingu og mögulegt er til að ná sem bestum árangri. |
| `scale` |  | number | no | `2` | 1 – 5 | Hækkaðu þennan kvarðastuðul til að gera úttaksmyndina stærri. |
| `creativity` |  | number | no | `0.5` | 0 – 1 | Leyfilegt frávik frá upprunanum. |
| `detail` |  | number | no | `1` | 0 – 5 | Magn viðbótarupplýsinga. |
| `shape_preservation` |  | number | no | `0.25` | 0 – 3 | Að hve miklu leyti lögun upprunamyndarinnar er varðveitt. |
| `prompt_suffix` |  | string | no | `high quality, highly detailed, high resolution, sharp` |  | Sameiginlegur endir kvaðningar fyrir innfellingartákn eða orðalag á borð við 'high quality' í allar kvaðningar. |
| `negative_prompt` |  | string | no | `blurry, low resolution, bad, ugly, low quality, pixelated, interpolated, compression artifacts, noisey, grainy` |  | Neikvæð kvaðning sem tilgreinir óæskileg smáatriði myndar. Hún getur útilokað liti, hluti, landslag eða fínni eiginleika og gæði, svo sem yfirvaraskegg, óskýring eða lága upplausn. |
| `seed` |  | integer \| null | no |  |  | Sáð til að endurgera myndir í Stable Diffusion. Hægt er að endurgera mynd nákvæmlega í hverri keyrslu með því að halda útgáfu líkans, kvaðningu og sáði óbreyttum. |

| `additional_lora_url` |  | string | no |  |  | Tilgreindu viðbótar-LORA fyrir stækkun með því að gefa upp vefslóð líkansins. Án gildis er sjálfgefið None. |
| `additional_lora_scale` |  | number | no | `1` |  | Stilltu hversu sterk áhrif viðbótar-LORA hefur á stækkun með kvarðastillingu hennar, sem er sjálfgefið 1.0. |
| `additional_embedding_url` |  | string | no |  |  | Gefðu upp viðbótarinnfellingar fyrir stækkun með því að vísa á þær með vefslóð. Án gildis er sjálfgefið 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`.

## Example input

Required parameters only:

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

A fuller example:

```json

}
```

## 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.ru/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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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", {
  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.ru/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.ru/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.

### Output fields (`output`)

| Field | Type | Description |
|---|---|---|
| `image` | object {url, content_type, file_name, file_size, width, height} | Skráarupplýsingar fyrir myndina sem var búin til. |
| `seed` | integer | Sáðgildi fyrir myndgerð, þar með talið slembivalið gildi ef inntakið innihélt ekkert sáðgildi; annars endurtekur það gefna gildið. |
