# Topaz Image Upscale API

> Uas-scálaitheoir íomhánna Topaz Labs le hathshlánú aghaidhe, díthorannú agus géarú, suas le 4x.

Méadaíonn sé grianghraf nó rindreáil suas le ceithre huaire le samhlacha Topaz atá tiúnta d'fhoinsí éagsúla: grianghraif chaighdeánacha, dílseacht ard, foinsí ísealtaifigh, CGI, téacs agus aghaidheanna. Feabhsú aghaidhe roghnach, díthorannú, géarú agus deisiú comhbhrúite; aschur JPEG nó PNG.

- Model id: `topaz/upscale/image/precision`
- Made by: Topaz Labs
- Category: Upscale
- Output: image
- Price per 24 megapixels of your output image: $0.08 / 24 megapixels of output image (cheapest run $0.08 (80 API credits))
- Run: `POST https://api.doitong.com/v1/run/topaz/upscale/image/precision`
- Quote: `POST https://api.doitong.com/v1/quote/topaz/upscale/image/precision`
- Docs page: https://doitong.com/ga/developers/models/topaz/upscale/image/precision

## Pricing

Price: **$0.08 / 24 megapixels of output image**. Price per 24 megapixels 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 (1 × 24 MP output image × $0.08).

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/precision` 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 | URL na híomhá foinse le haghaidh uas-scálaithe. |
| `model` |  | enum (string) | no | `Standard V2` | `Standard V2`, `High Fidelity V3`, `High Fidelity V2`, `Low Resolution V2`, `CGI`, `Text Refine`, `Faces` | Roghnú samhla uas-scálaithe beacht: úsáideann Faces Face Recovery 3 le haghaidh atógáil aghaidhe, coinníonn Text Refine téacs agus cruthanna géara, agus oireann CGI do shaothair ealaíne agus grafaicí rindreáilte. Maidir le grianghraif, clúdaíonn Standard V2 formhór na n-úsáidí, coinníonn High Fidelity V3 agus High Fidelity V2 mionsonraí grianghraf gairmiúil, agus atógann Low Resolution V2 foinsí comhbhrúite. |
| `upscale_factor` |  | number | no | `2` | 1 – 4 | Iolraitheoir méadaithe na híomhá; mar shampla, dúblaíonn 2.0 an dá thoise. |
| `crop_to_fill` |  | boolean | no | `false` |  |  |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png` | Formáid a úsáidtear don íomhá uas-scálaithe. |
| `subject_detection` |  | enum (string) | no | `All` | `All`, `Foreground`, `Background` | Socrú braite ábhair a úsáidtear le linn feabhsú íomhá. |
| `face_enhancement` |  | boolean | no | `true` |  | Scorán feabhsaithe aghaidhe don íomhá. |
| `face_enhancement_creativity` |  | number | no | `0` | 0 – 1 | Rialú cruthaitheachta feabhsaithe aghaidhe, gníomhach agus feabhsú aghaidhe cumasaithe amháin: socraigh 1.0 don chruthaitheacht uasta nó 0.0 d’aon cheann. |
| `face_enhancement_strength` |  | number | no | `0.8` | 0 – 1 | Rialú neart feabhsaithe aghaidhe, gníomhach agus feabhsú aghaidhe cumasaithe amháin: socraigh 1.0 don fheabhsú uasta nó 0.0 d’aon cheann. |
| `sharpen` |  | number \| null | no |  | 0 – 1 | Déine géaraithe ó 0.0 go 1.0, le réamhshocrú a bhraitheann ar an tsamhail. |
| `denoise` |  | number \| null | no |  | 0 – 1 | Déine laghdaithe torainn ó 0.0 go 1.0, le réamhshocrú a bhraitheann ar an tsamhail. |
| `fix_compression` |  | number \| null | no |  | 0 – 1 | Déine bhaint déantán comhbhrúite ó 0.0 go 1.0; níl sé ar fáil le CGI. |
| `strength` |  | number \| null | no |  | 0.01 – 1 | Déine feabhsaithe ó 0.01 go 1.0, le Text Refine amháin. |

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": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "upscale_factor": 2
}
```

## 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/precision?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "upscale_factor": 2
  }'

# 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/topaz/upscale/image/precision?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "upscale_factor": 2
  }),
});
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": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "upscale_factor": 2,
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/topaz/upscale/image/precision", 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/precision",
      "input": {
        "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "upscale_factor": 2
      },
      "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.
