# LTX 2.5 Pro Image to Video API

> Anime une image de départ, éventuellement vers une image finale, pour créer un extrait LTX 2.5 Pro de 6 à 10 secondes avec audio.

LTX 2.5 Pro anime votre première image, peut terminer sur une image finale, ajoute un audio généré et accepte un mouvement de caméra nommé (dolly, jib, static ou focus shift). 6, 8 ou 10 secondes ou durée automatique, 720p ou 1080p, 24, 25 ou 50 fps.

- Model id: `lightricks/ltx-2.5/image-to-video/pro`

- Output: video
- Price: from $0.12 / second (6 s ≈ $0.72) (cheapest run $0.72 (720 API credits))
- Run: `POST https://api.doitong.ru/v1/run/lightricks/ltx-2.5/image-to-video/pro`
- Quote: `POST https://api.doitong.ru/v1/quote/lightricks/ltx-2.5/image-to-video/pro`
- Docs page: https://doitong.com/fr-FR/developers/models/lightricks/ltx-2.5/image-to-video/pro

## 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

| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `16:9`, `9:16` | Format de la vidéo, avec un réglage dérivé de l’image disponible via 'auto'. |
| `fps` |  | enum (integer) | no | `25` | `24`, `25`, `50` | Fréquence d’images de la vidéo de sortie, mesurée en images par seconde. |
| `generate_audio` |  | boolean | no | `true` |  | Option de génération audio pour la vidéo de sortie. |

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"
}
```

A fuller example:

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

## 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" \
  -d '{
    "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"
  }'

# 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"
```

### Python

```python
import os
import requests

API = "https://api.doitong.ru/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "Fireflies swirl around the fox as it slows down and looks back over its shoulder",

}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/lightricks/ltx-2.5/image-to-video/pro", 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()

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": "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.
