# LTX 2.5 Pro Image to Video API

> Animeert een startafbeelding, optioneel richting een eindafbeelding, tot een LTX 2.5 Pro-clip van 6 tot 10 seconden met audio.

LTX 2.5 Pro animeert je eerste frame, kan eindigen op een eindframe, voegt gegenereerde audio toe en accepteert een benoemde camerabeweging (dolly, jib, static of focus shift). 6, 8 of 10 seconden of automatische lengte, 720p of 1080p, 24, 25 of 50 fps.

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

- Category: Image to Video
- 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`

## 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.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `image_url` | `image` | string (image URL) | yes |  |  | URL naar de afbeelding waarmee de uitvoervideo begint. |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | Optioneel overgangsdoel, opgegeven als afbeeldings-URL. Hierdoor gaat de gegenereerde video over van het startframe naar deze eindafbeelding. |
| `prompt` |  | string | yes |  | 1 – 5000 characters | Prompt die videogeneratie aanstuurt. |
| `duration` |  | enum | no | `auto` | `6`, `8`, `10`, `auto` | Selectie van videoduur: geef een duur in seconden op of kies 'auto' om het model te laten beslissen. De maximale duur is 10 seconden. |
| `resolution` |  | enum (string) | no | `1080p` | `720p`, `1080p` | Resolutie van de uitvoervideo. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `16:9`, `9:16` | Beeldverhouding van de video, waarbij een uit de afbeelding afgeleide instelling beschikbaar is via 'auto'. |
| `fps` |  | enum (integer) | no | `25` | `24`, `25`, `50` | Framesnelheid van de uitvoervideo, gemeten in frames per seconde. |
| `generate_audio` |  | boolean | no | `true` |  | Schakelaar voor audiogeneratie in de uitvoervideo. |
| `camera_motion` |  | enum (string) \| null | no |  | `dolly_in`, `dolly_out`, `dolly_left`, `dolly_right`, `jib_up`, `jib_down`, `static`, `focus_shift` | Optionele camerabeweging voor de uitvoervideo. |

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()
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": "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.
