# MOSS Image API

> Model da text a maletg per text chinais ed englais en maletgs, cun prompts conscients da la disposiziun e l'engrondiment opziunal

Generescha maletgs dad in `prompt` da fin a 16384 caracteris, scrit en lingua natirala, sequenzas da tags u layouts JSON, quai che gida a plazzar precisamain text e objects. L'expansiun dal prompt planisescha l'emprim in layout structurà ed è activa tenor standard. Las grondezzas derivan da sis preselecziuns (quadratic, portrait e format panoramic), arrotondadas a multipels da 16 tranter 512 e 2048 pixel. Ti pos dumandar 1 fin 4 maletgs cun 1 fin 100 pass, definir `guidance_scale` da 0 fin 10, utilisar in `negative_prompt` e `seed`, e generar PNG, JPEG u WebP.

- Model id: `moss-image`
- Made by: Open model
- Category: Text to Image
- Output: image
- Price: $0.05 / megapixel (cheapest run $0.05 (50 API credits))
- Run: `POST https://api.doitong.com/v1/run/moss-image`
- Quote: `POST https://api.doitong.com/v1/quote/moss-image`
- Docs page: https://doitong.com/rm/developers/models/moss-image

## Pricing

Price: **$0.05 / 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 $0.05 = 50 API credits (1 MP × 50 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.com/v1/quote/moss-image` 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 – 16384 characters | Prompt da generaziun da maletgs che accepta lingua natirala, sequenzas da tags u layouts JSON. |
| `negative_prompt` |  | string | no | `` | ≤ 16384 characters | Prompt negativ utilisà per la guidance, cun il skipping da la transfurmader-layer che furnescha la branscha negativa sche il prompt è vid. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Perfecziunament dal prompt che mantegna mintga text visibel dumandà, planisond in layout structurat per las dimensiuns dal maletg tschernidas avant la generaziun. Il prompt original resta en diever sche il perfecziunament n’è betg disponibel. |
| `image_size` |  | object {width, height} \| enum (string) | no | `square_hd` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | Dimensiuns da l’output limitadas a 512–2048 pixels tant per la ladezza sco per l’autezza, cun mintga valur arrotondada ad in multipel da 16. |
| `num_inference_steps` |  | integer | no | `50` | 1 – 100 | Dumber da pass da denoisaziun da far. |
| `guidance_scale` |  | number | no | `3` | 0 – 10 | Furma da la guida senza classificatur. |
| `seed` |  | integer \| null | no |  |  | Semenza casuala che renda la generaziun reproducibla. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Dumber da maletgs da producir. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Controlla da moderaziun da l’output che mo contos autorisads pon deactivar; tut las autras dumondas vegnan controlladas independentamain da questa configuraziun. In maletg nair vegn returnà enstagl da mintga maletg marcà sco betg segir. |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png`, `webp` | Format dal maletg resultà. |

## Example input

Required parameters only:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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/moss-image?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"
  }'

# 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/moss-image?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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 = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/moss-image", 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": "moss-image",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
