# Hidream O1 Image · Dev · Edit API

> Variante dev distillée pour la retouche à partir d'images de référence, 28 étapes et guidage 0 par défaut

Modifie ou personnalise des images à partir d'images de référence (`reference_image_urls`) et d'un `prompt` textuel, avec le modèle dev distillé et optimisé pour 28 étapes, l'échelle de guidage étant définie par défaut sur 0. La sortie atteint environ 2048x2048 via des préréglages de taille ou des dimensions personnalisées. Renvoie de 1 à 4 images en PNG, JPEG ou WebP, et `keep_original_aspect` conserve la forme d'une référence unique.

- Made by: HiDream
- Category: Image Editing
- Output: image
- Price: $0.005 / megapixel (cheapest run $0.02 (20 API credits))
- Run: `POST https://api.doitong.ru/v1/run/hidream-o1-image/dev/edit`
- Quote: `POST https://api.doitong.ru/v1/quote/hidream-o1-image/dev/edit`

## Pricing

Price: **$0.005 / megapixel**. Billed per megapixel of output (width × height of every image). Each image is rounded up to a whole megapixel.

The full example input below costs $0.02 = 20 API credits (4 MP × 5 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.ru/v1/quote/hidream-o1-image/dev/edit` 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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  | ≥ 1 characters | Instructions textuelles pour générer ou modifier des images, ou pour une personnalisation guidée par le sujet. |
| `reference_image_urls` | `images` | array of image URL | yes |  | ≥ 1 items | Images fournies comme références pour la modification ou la personnalisation guidée par le sujet. |
| `image_size` |  | object {width, height} \| enum (string) | no | `{"height":2048,"width":2048}` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | Choisissez les dimensions de l'image ; pour les sorties basées sur des images de référence, cette requête est adaptée à la résolution prise en charge par le modèle qui s'en rapproche le plus, avec un maximum approximatif de 2048 × 2048 pixels. |
| `num_inference_steps` |  | integer | no | `28` | 1 – 28 | Nombre d'itérations de débruitage, 28 étapes correspondant à la cible de distillation du modèle dev. |
| `guidance_scale` |  | number | no | `0` | 0 – 20 | Échelle du guidage sans classifieur ; par défaut à 0.0 pour le modèle dev. |
| `seed` |  | integer \| null | no |  |  | Seed aléatoire rendant la génération reproductible. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Nombre d’images à produire. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Format de fichier de l'image obtenue. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Indique si les images générées sont soumises à un contrôle de sécurité. |
| `keep_original_aspect` |  | boolean | no | `false` |  | Conservation du rapport largeur-hauteur pour une génération avec une seule référence : la sortie reprend les proportions de cette référence uniquement lorsqu'une seule image est fournie. |

File parameters (`images`) 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
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  ]
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "reference_image_urls": [
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  ]
}
```

## 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/hidream-o1-image/dev/edit?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
    "reference_image_urls": [
      "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/hidream-o1-image/dev/edit?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({

    "reference_image_urls": [
      "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 = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
    "reference_image_urls": [
        "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/hidream-o1-image/dev/edit", 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": "hidream-o1-image/dev/edit",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "reference_image_urls": [
          "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.
