# Ltx 2.3 Quality · Ingredient API

> Кейіпкерлер, нысандар және орын көрсетілген анықтамалық парақтан қосымша жасалған аудиосы бар бейне жасайды

Кейіпкерлерді, нысандарды және ортаны бірізді сақтау үшін таза панельдері бар анықтамалық параққа сілтейтін мәтіндік `prompt` пен `image_url` негізінде бейне жасайды. `ingredient_strength` және `reference_strength` (0-ден 2-ге дейін) парақтың нәтижеге әсер ету деңгейін басқарады. `num_frames` 9 бен 481 аралығында, `frames_per_second` 1 мен 60 аралығында болады, ал аудионы `generate_audio` арқылы өшіруге болады.

## Pricing

Price: **$0.00241 / megapixel of output video**. Price per megapixel of your output video: 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 $0.27 = 270 API credits (112 MP output video × $0.002408).

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/ltx-2.3-quality/ingredient` 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 |  |  | Бейне генерациясын бағыттайтын мәтін. Оңтайлы нәтиже үшін оны 'Reference sheet: ... Generated video: ...' пішімінде ұйымдастырыңыз. |
| `image_url` | `image` | string (image URL) | yes |  |  | Сақталуы тиіс нысандарды анықтайтын Ingredient анықтамалық парағы кескінінің URL мекенжайы: кейіпкерлер, реквизиттер және орын парақта таза панельдерде көрінуі керек. |

Әдепкі мән жұмыс ағынының бастапқы кезеңі үшін Ingredient LoRA оқыту шелегіндегі 768x448 өлшемін сақтайды. |
| `frames_per_second` |  | number | no | `24` | 1 – 60 | Секундына кадрмен өлшенетін шығыс бейнесінің кадр жиілігі. |
| `guidance_scale` |  | number | no | `1` | 1 – 20 | Classifier-free guidance күші. |
| `ingredient_strength` |  | number | no | `1` | 0 – 2 | Қосылған Ingredient IC-LoRA үшін бұл күш параметрін арттырған сайын анықтамалық парақтағы тұлғалар мен реквизиттер айқынырақ болады. |
| `reference_strength` |  | number | no | `1` | 0 – 2 | Анықтамалық парақты бағыттау күші: модельге көбірек еркіндік беру үшін азайтыңыз немесе парақты толық қолдану үшін 1.0 мәнін пайдаланыңыз. |
| `generate_audio` |  | boolean | no | `true` |  | Қайтарылатын MP4 үшін аудио жолы ауыстырғышы: өшірулі болса тек бейне файлы жасалады, қосулы болса аудио қосылады. |
| `negative_prompt` |  | string | no | `worst quality, inconsistent motion, blurry, jittery, distorted` |  | Генерацияда болмауы тиіс нәрселерді көрсететін теріс нұсқау. |
| `seed` |  | integer \| null | no |  |  | Генерацияны қайта өндіруге мүмкіндік беретін seed. None мәнін орнатсаңыз, seed кездейсоқ таңдалады. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Нұсқауды кеңейту қосылған-қосылмағанын басқарады. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Қауіпсіздікті тексерудің қосылған-қосылмағанын басқарады. |

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/ltx-2.3-quality/ingredient?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",
    "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/ltx-2.3-quality/ingredient?wait=20", {
  method: "POST",
  headers,

  }),
});
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",
    "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/ltx-2.3-quality/ingredient", 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": "ltx-2.3-quality/ingredient",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "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.
