# Creative Upscaler API

> Upscaler creativo basato sulla diffusione che aggiunge dettagli, con base SD 1.5 o SDXL e controllo della forma

Ingrandisce un'immagine da `image_url` di un fattore `scale` da 1 a 5 generando nuovi dettagli. `model_type` è SD_1_5 o SDXL, `creativity` e `detail` determinano l'entità delle modifiche, mentre `shape_preservation` mantiene la struttura originale. Senza `prompt`, ne viene generato uno automaticamente. Sono supportati URL personalizzati per il modello base, LoRA ed embedding.

- 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/it/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` | Tipo di modello usato per l'upscaling; il valore predefinito è SD_1_5. |
| `image_url` | `image` | string (image URL) | yes |  |  | Immagine sorgente per l'upscaling. |
| `prompt` |  | string \| null | no |  |  | Prompt per la generazione dell'immagine, creato da BLIP2 quando lo ometti. Quando ne fornisci uno personalizzato, includi più dettagli descrittivi possibile per ottenere i risultati migliori. |
| `scale` |  | number | no | `2` | 1 – 5 | Aumenta questo fattore di scala per rendere più grande l'immagine di output. |
| `creativity` |  | number | no | `0.5` | 0 – 1 | Grado di deviazione consentito rispetto all'originale. |
| `detail` |  | number | no | `1` | 0 – 5 | Quantità di dettagli aggiunti. |
| `shape_preservation` |  | number | no | `0.25` | 0 – 3 | Grado di conservazione della forma dell'immagine sorgente. |
| `prompt_suffix` |  | string | no | `high quality, highly detailed, high resolution, sharp` |  | Finale di prompt condiviso per aggiungere token di embedding o espressioni come 'high quality' a tutti i prompt. |
| `negative_prompt` |  | string | no | `blurry, low resolution, bad, ugly, low quality, pixelated, interpolated, compression artifacts, noisey, grainy` |  | Prompt negativo che specifica i dettagli indesiderati dell'immagine. Può escludere colori, oggetti, scenari o caratteristiche e qualità più fini, come baffi, sfocatura o bassa risoluzione. |
| `seed` |  | integer \| null | no |  |  | Seed per riprodurre immagini in Stable Diffusion. Un'immagine può essere riprodotta esattamente a ogni esecuzione mantenendo invariati la versione del modello, il prompt e il seed. |
| `guidance_scale` |  | number | no | `7.5` | 0 – 16 | Intensità di aderenza al prompt per la selezione dell'immagine, espressa come CFG (Classifier Free Guidance). |
| `num_inference_steps` |  | integer | no | `20` | 1 – 200 | Numero di passaggi di inferenza per la generazione dell'immagine; valori più elevati migliorano la qualità dell'immagine a fronte di un tempo di generazione maggiore. |
| `enable_safety_checks` |  | boolean | no | `true` |  | Opzione di controllo di sicurezza che, quando è true, sostituisce con un'immagine nera ogni risultato rilevato come contenente contenuti potenzialmente non sicuri. |
| `skip_ccsr` |  | boolean | no | `false` |  | Esclusione della preelaborazione CCSR quando abilitata; l'immagine passa direttamente al modello di creatività. |
| `override_size_limits` |  | boolean | no | `false` |  | Autorizzazione per upload di grandi dimensioni che potrebbero richiedere molto tempo. |
| `base_model_url` |  | string \| null | no |  |  | URL del modello di base per l'upscaling. |
| `additional_lora_url` |  | string | no |  |  | Specifica una LORA aggiuntiva per l'upscaling fornendo l'URL del modello. Senza valore, il valore predefinito è None. |
| `additional_lora_scale` |  | number | no | `1` |  | Regola l'intensità con cui la LORA aggiuntiva influisce sull'upscaling tramite la relativa impostazione di scala, il cui valore predefinito è 1.0. |
| `additional_embedding_url` |  | string | no |  |  | Fornisci embedding aggiuntivi per l'upscaling indicandone l'URL. Senza valore, il valore predefinito è 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

## 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", {
  method: "POST",
  headers,
  body: JSON.stringify({

### 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.
