# LTX 2.5 Pro Text to Video API

> A Lightricks LTX 2.5 Pro modellje 6–10 másodperces, hanggal és névvel megadott kameramozgásokkal rendelkező klipeket készít, legfeljebb 1080p és 50 fps mellett.

Az LTX 2.5 Pro éles 720p vagy 1080p videót renderel generált hanggal, és lehetővé teszi, hogy leírás helyett névvel megadott kameramozgást (dolly in vagy out, sideways dolly, jib up vagy down, static, focus shift) válassz. 6, 8 vagy 10 másodperc, illetve automatikus hossz, 24, 25 vagy 50 fps, fekvő vagy álló tájolás.

- Run: `POST https://api.doitong.ru/v1/run/lightricks/ltx-2.5/text-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 $1.02 = 1020 API credits (6 s × 170 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/text-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.

## Example input

Required parameters only:

```json
{
  "prompt": "Through a sheer red veil, a bride smiles as marigold petals fall around her, warm evening light"
}
```

A fuller example:

```json
{
  "prompt": "Through a sheer red veil, a bride smiles as marigold petals fall around her, warm evening light",
  "duration": 6,
  "resolution": "1080p",
  "camera_motion": "dolly_in"
}
```

## 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/text-to-video/pro?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Through a sheer red veil, a bride smiles as marigold petals fall around her, warm evening light",
    "duration": 6,
    "resolution": "1080p",
    "camera_motion": "dolly_in"
  }'

# 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"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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/lightricks/ltx-2.5/text-to-video/pro?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({

    "duration": 6,
    "resolution": "1080p",
    "camera_motion": "dolly_in"
  }),
});
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.ru/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "Through a sheer red veil, a bride smiles as marigold petals fall around her, warm evening light",
    "duration": 6,
    "resolution": "1080p",
    "camera_motion": "dolly_in",
}

# 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/text-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/text-to-video/pro",
      "input": {
        "prompt": "Through a sheer red veil, a bride smiles as marigold petals fall around her, warm evening light",
        "duration": 6,
        "resolution": "1080p",
        "camera_motion": "dolly_in"
      },
      "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.
