# Cosmos 3 Super API

> Giniúint téacs-go-híomhá le leathnú leide agus mód roghnach gníomhach chun iarrthóirí a chur i gcomparáid

Cruthaíonn sé 1 go 4 íomhá ó `prompt` suas le 4096 carachtar. Clampáiltear imill `image_size` idir 512-1280 px. Gineann `enable_agentic_generation` roinnt iarrthóirí agus mionchoigeartaíonn sé an leid idir babhtaí, le suas le 3 atriall. Tá `negative_prompt`, `guidance_scale` suas le 20, `num_inference_steps` suas le 50, agus aschur jpeg nó png aige freisin.

- Model id: `nvidia/cosmos-3-super/text-to-image`
- Made by: NVIDIA
- Category: Text to Image
- Output: image
- Price per run: from $0.04 / run of output image (cheapest run $0.04 (40 API credits))
- Run: `POST https://api.doitong.ru/v1/run/nvidia/cosmos-3-super/text-to-image`
- Quote: `POST https://api.doitong.ru/v1/quote/nvidia/cosmos-3-super/text-to-image`
- Docs page: https://doitong.com/ga/developers/models/nvidia/cosmos-3-super/text-to-image

## Pricing

Price: **from $0.04 / run of output image** (the lowest tier; the quote prices your exact input). Price per run: 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 $0.04 = 40 API credits (1 run × $0.04).

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/nvidia/cosmos-3-super/text-to-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 – 4096 characters | Cur síos téacs ar an íomhá aschuir atá inmhianaithe. |
| `negative_prompt` |  | string | no | `` | ≤ 1024 characters | Treoir dhiúltach lena sainaithnítear dathanna, réada nó déantáin nach dteastaíonn le seachaint sa ghiniúint. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Feabhsú leid roimh an nginiúint trí OpenRouter, a tháirgeann an léiriú dlúth struchtúrtha JSON a úsáidtear chun Cosmos3 a oiliúint nuair atá sé cumasaithe. Má theipeann ar an bhfeabhsú, leanann giniúint na híomhá ar aghaidh leis an leid neamhathraithe. |
| `enable_agentic_generation` |  | boolean | no | `false` |  | Lúb uathoibríoch scagtha leide atá dírithe ar chloí níos fearr leis an iarratas bunaidh. Gineann gach babhta iliomad iarrthóirí íomhá agus cuireann sé i gcomparáid iad, le hathruithe ar an leid idir na babhtaí. |
| `agentic_max_iterations` |  | integer | no | `2` | 1 – 3 | Teorainn bhabhtaí scagtha don ghiniúint nuair atá mód gníomhaireach cumasaithe. |
| `agentic_samples_per_iteration` |  | integer | no | `2` | 1 – 3 | Líon iarrthóirí íomhá in aghaidh atriall don lúb ghníomhaireach, a chinneann cé mhéad íomhá a théann san iomaíocht sa mheasúnú sula leanann an ceann is fearr ar aghaidh chuig athscríobh na leide. |
| `agentic_early_stop` |  | boolean | no | `true` |  | Rialú stad luath a mheasann gur leor meaitseáil láidir íomhá-le-leid chun críochnú gan atriallta breise. |
| `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` | Socraigh toisí na híomhá aschuir; coinníonn teorannú gach ciumhais idir 512 agus 1280px, agus ní cheadaítear ach faid chiumhais ar iolraí de 16. |
| `num_inference_steps` |  | integer | no | `28` | 1 – 50 | Líon na gcéimeanna dí- torainn, áit a mbíonn próiseáil níos faide mar thoradh ar líon níos airde ar mhaithe le cáilíocht níos fearr. |
| `guidance_scale` |  | number | no | `4` | 0 – 20 | Neart na treorach gan aicmitheoir. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Líon na n-íomhánna a iarrtar don ghiniúint. |
| `seed` |  | integer \| null | no |  |  | Síl le haghaidh giniúint íomhá in-atáirgthe. Fanann an íomhá aschuir gan athrú idir ritheanna mura n-athraíonn an tsíl, an leid nó leagan na samhla. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Lasc modhnóireachta ábhair a chlúdaíonn ionchur na leide agus aschur na híomhá araon. Ní mór do chuntais a bheith údaraithe chun modhnóireacht a sheachaint; murach sin, fanann na seiceálacha éigeantach beag beann ar an socrú. Cuirtear íomhá dhubh in áit aon íomhá a mheastar a bheith neamhshábháilte. |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png` | Formáid comhaid na híomhá deiridh. |

## 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.ru/v1/run/nvidia/cosmos-3-super/text-to-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.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/nvidia/cosmos-3-super/text-to-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.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",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/nvidia/cosmos-3-super/text-to-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.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": "nvidia/cosmos-3-super/text-to-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.
