# Topaz Upscale Image Generative API

> Generatiivinen kuvan suurentaja, jossa on useita malleja, kasvojen parannus ja kehotteella ohjattava Redefine-tila

Suurentaa kuvan 1x–4x valitulla `model`-mallilla, kuten Wonder 3.5, Wonder 3, Recover 3, Redefine ja Recovery V2. Kasvojen parannuksella on omat voimakkuus- ja luovuussäätimensä. Redefine lisää enintään 1024 merkin `prompt`-kehotteen sekä `creativity`-, `texture`-, `sharpen`- ja `denoise`-asetukset. Sopii pienille tai sumeille lähdekuville.

- Model id: `topaz/upscale/image/generative`
- Made by: Topaz Labs
- Category: Upscale
- Output: image
- Price per megapixel of your output image: from $0.01 / megapixel of output image (cheapest run $0.01 (10 API credits))
- Run: `POST https://api.doitong.com/v1/run/topaz/upscale/image/generative`
- Quote: `POST https://api.doitong.com/v1/quote/topaz/upscale/image/generative`
- Docs page: https://doitong.com/fi/developers/models/topaz/upscale/image/generative

## Pricing

Price: **from $0.01 / megapixel of output image** (the lowest tier; the quote prices your exact input). Price per megapixel of your output image: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $0.08 = 80 API credits (8 MP output image × $0.01).

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/topaz/upscale/image/generative` 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 |  | ≥ 1 characters | Skaalattavan lähdekuvan URL-osoite. |
| `model` |  | enum (string) | no | `Wonder 3` | `Wonder 3.5`, `Wonder 3`, `Wonder 2`, `Wonder`, `Recover 3`, `Standard MAX`, `Redefine`, `Recovery V2`, `Recovery` | Generatiivisen skaalauksen mallin valinta: Recovery ja Recovery V2 rekonstruoivat erittäin pieniresoluutioisia kuvia, Redefine ohjaa luovaa yksityiskohtaa kehotteilla, Standard MAX painottaa tarkkuutta ja laatua, ja Recover 3 rekonstruoi luonnollisia yksityiskohtia. Wonder-malliperheessä Wonder ja Wonder 2 edeltävät Wonder 3:a, edistyneintä generatiivisen realismin mallia; uusin julkaisu Wonder 3.5 tuottaa hienompia yksityiskohtia ja vähemmän kuvioiden toistoa. |
| `upscale_factor` |  | number | no | `2` | 1 – 4 | Kuvan suurennuskerroin; esimerkiksi 2.0 kaksinkertaistaa molemmat mitat. |
| `crop_to_fill` |  | boolean | no | `false` |  |  |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png` | Skaalatun kuvan käyttämä muoto. |
| `subject_detection` |  | enum (string) | no | `All` | `All`, `Foreground`, `Background` | Määrittää, miten kohteet tunnistetaan kuvia Recovery V2:lla, Wonder 3:lla tai Recoverylla parannettaessa. |
| `face_enhancement` |  | boolean | no | `true` |  | Kuvan kasvojenparannuksen valitsin. |
| `face_enhancement_creativity` |  | number | no | `0` | 0 – 1 | Kasvojenparannuksen luovuuden säätö, aktiivinen vain kasvojenparannuksen ollessa käytössä: aseta 1.0 enimmäisluovuudelle tai 0.0 luovuuden poistamiseksi. |
| `face_enhancement_strength` |  | number | no | `0.8` | 0 – 1 | Kasvojenparannuksen voimakkuuden säätö, aktiivinen vain kasvojenparannuksen ollessa käytössä: aseta 1.0 enimmäisparannukselle tai 0.0 parannuksen poistamiseksi. |
| `enhancement_strength` |  | enum (string) \| null | no |  | `low`, `medium`, `high` | Generatiivisen skaalauksen parannuksen voimakkuus; määritetään automaattisesti, jos sitä ei anneta. Tuetut mallit ovat Wonder 3.5 ja Wonder 3. |
| `creativity` |  | integer \| null | no |  | 1 – 6 | Generatiivisen skaalauksen luovuus välillä 1–6, vain Redefinen tukema. Suurempi arvo lisää mielikuvituksellisia tai hallusinoituja yksityiskohtia. |
| `texture` |  | integer \| null | no |  | 1 – 5 | Redefinen generatiiviselle skaalaukselle tarkoitettu tekstuurin yksityiskohtien säätö, jonka taso voi olla 1–5. |
| `prompt` |  | string \| null | no |  | ≤ 1024 characters | Generatiivisen skaalauksen ohjeteksti, enintään 1024 merkkiä ja vain Redefinen tukema. |
| `autoprompt` |  | boolean \| null | no |  |  | Automaattisen kehotteen generoinnin valitsin, käytettävissä vain Redefinen generatiivisessa skaalauksessa. |
| `sharpen` |  | number \| null | no |  | 0 – 1 | Terävöityksen voimakkuus välillä 0.0–1.0, vain Redefinen tukema. |
| `denoise` |  | number \| null | no |  | 0 – 1 | Kohinanpoiston voimakkuus välillä 0.0–1.0, vain Redefinen tukema. |
| `detail` |  | number \| null | no |  | 0 – 1 | Yksityiskohtien palautuksen voimakkuus välillä 0.0–1.0, vain Recovery V2:n tukema. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Suodatusta voi höllentää asettamalla arvoksi false, jos kutsujalla on siihen valtuutus. |

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:

```

## 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/topaz/upscale/image/generative?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 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/topaz/upscale/image/generative", 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": "topaz/upscale/image/generative",
      "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.
