# Ltx 2.3 Quality · Ingredient API

> Picha hadi video kutoka kwenye laha ya marejeo ya wahusika, vifaa na eneo, ikiwa na sauti iliyotengenezwa ya hiari

Hujenga video kutoka kwa `prompt` ya maandishi na `image_url` inayoelekeza kwenye laha ya marejeo yenye paneli safi za wahusika, vifaa na mandhari ili kudumisha uthabiti. `ingredient_strength` na `reference_strength` (0 hadi 2) hudhibiti nguvu ya laha katika kuongoza matokeo. `num_frames` ni 9 hadi 481, `frames_per_second` ni 1 hadi 60, na sauti inaweza kuzimwa kwa `generate_audio`.

## 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 |  |  | Maandishi yanayoelekeza uzalishaji wa video. Kwa matokeo bora, yapange kama 'Reference sheet: ... Generated video: ...'. |
| `image_url` | `image` | string (image URL) | yes |  |  | URL ya picha ya laha ya marejeleo ya Ingredient inayobainisha cha kuhifadhi: wahusika, vifaa na eneo vinapaswa kuonekana katika paneli safi kwenye laha. |
| `num_frames` |  | integer | no | `121` | 9 – 481 | Idadi ya fremu za tokeo lililozalishwa. |
| `resolution` |  | object {width, height} \| enum (string) | no | `{"height":896,"width":1536}` | `auto`, `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | Vipimo vya mwisho vya video, vinavyofuata hatua rasmi ya uboreshaji ya 2x. Chaguomsingi huhifadhi bucket ya mafunzo ya Ingredient LoRA ya 768x448 kwa hatua ya awali ya mtiririko. |
| `frames_per_second` |  | number | no | `24` | 1 – 60 | Kiwango cha fremu za video ya tokeo, kinachopimwa kwa fremu kwa sekunde. |
| `guidance_scale` |  | number | no | `1` | 1 – 20 | Nguvu ya mwongozo usio na klasifaya. |
| `ingredient_strength` |  | number | no | `1` | 0 – 2 | Utambulisho na vifaa vya laha ya marejeleo huonekana zaidi unapoongeza mpangilio huu wa nguvu kwa Ingredient IC-LoRA iliyojumuishwa. |
| `reference_strength` |  | number | no | `1` | 0 – 2 | Nguvu ya mwongozo wa laha ya marejeleo: ipunguze kwa uhuru zaidi wa modeli, au tumia 1.0 kutumia laha kikamilifu. |
| `generate_audio` |  | boolean | no | `true` |  | Kigeuzi cha wimbo wa sauti kwa MP4 inayorejeshwa: ikiwa kimezimwa hutengeneza faili ya video pekee, na kikiwa kimewashwa hujumuisha sauti. |
| `negative_prompt` |  | string | no | `worst quality, inconsistent motion, blurry, jittery, distorted` |  | Kidokezo hasi kinachobainisha kile ambacho uzalishaji unapaswa kuepuka. |
| `seed` |  | integer \| null | no |  |  | Seed inayofanya uzalishaji uweze kurudiwa. Kuiweka kuwa None huchagua seed bila mpangilio. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Hudhibiti ikiwa upanuzi wa kidokezo umewashwa. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Hudhibiti ikiwa ukaguzi wa usalama umewashwa. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Preset ya ubora inayotumika kwenye video ya tokeo. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Hali ya kuandika ya video inayotokana. |

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`.

}
```

## 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

request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is

### 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.
