# LTX 2.5 Pro Image to Video API

> Huunda uhuishaji kutoka picha ya mwanzo, ikiweza kuelekea kwenye picha ya mwisho, kuwa klipu ya LTX 2.5 Pro ya sekunde 6 hadi 10 yenye sauti.

Picha-hadi-video ya LTX 2.5 Pro huunda uhuishaji wa fremu yako ya kwanza, inaweza kumalizia kwenye fremu ya mwisho, huongeza sauti inayozalishwa na hukubali mjongeo wa kamera uliotajwa (dolly, jib, static au focus shift). Sekunde 6, 8 au 10 au urefu wa kiotomatiki, 720p au 1080p, 24, 25 au 50 fps.

## Pricing

Price: **from $0.12 / second (6 s ≈ $0.72)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 10).

The full example input below costs $0.72 = 720 API credits (6 s × 120 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/lightricks/ltx-2.5/image-to-video/pro` 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.

| `resolution` |  | enum (string) | no | `1080p` | `720p`, `1080p` | Mwonekano unaotumika kwa video ya tokeo. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `16:9`, `9:16` | Uwiano wa video, ukiwa na mpangilio unaotokana na picha kupitia 'auto'. |
| `fps` |  | enum (integer) | no | `25` | `24`, `25`, `50` | Kasi ya fremu ya video ya tokeo, iliyopimwa kwa fremu kwa sekunde. |
| `generate_audio` |  | boolean | no | `true` |  | Kigeuza uzalishaji wa sauti kwa video ya tokeo. |

File parameters (`image`, `end_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
{
  "prompt": "Fireflies swirl around the fox as it slows down and looks back over its shoulder",
  "image": "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/lightricks/ltx-2.5/image-to-video/pro?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \

    "duration": 6,
    "resolution": "720p",
    "camera_motion": "static"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.ru/v1/requests/REQUEST_ID?wait=20" \

### 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": "lightricks/ltx-2.5/image-to-video/pro",
      "input": {
        "prompt": "Fireflies swirl around the fox as it slows down and looks back over its shoulder",
        "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "duration": 6,
        "resolution": "720p",
        "camera_motion": "static"
      },
      "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.
