# LTX Video-0.9.7 13B Distilled API

> Texta-í-myndband með eldra 0.9.7 eimuðu 13B-líkani sem styður LoRA-viðbætur og langan rammafjölda

Býr til myndband úr nauðsynlegri `prompt` með destilled 0.9.7-líkaninu. Upplausn er 480p eða 720p, stærðarhlutfall 9:16, 1:1 eða 16:9 og `num_frames` getur verið 9 til 1441 við 1 til 60 fps. Hvor af tveimur sýnatökuferðum tekur 2 til 12 skref. Valfrjáls `loras`, auka smáatriðaferð og útvíkkun kvaðningar eru í boði.

- Model id: `ltx-video-13b-distilled`
- Made by: Lightricks
- Category: Text to Video
- Output: video
- Price per second of your output video: from $0.04 / second of output video (cheapest run $0.04 (40 API credits))
- Run: `POST https://api.doitong.com/v1/run/ltx-video-13b-distilled`
- Quote: `POST https://api.doitong.com/v1/quote/ltx-video-13b-distilled`
- Docs page: https://doitong.com/is/developers/models/ltx-video-13b-distilled

## Pricing

Price: **from $0.04 / second of output video** (the lowest tier; the quote prices your exact input). Price per second 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 $0.202 = 202 API credits (5.0417 s output video × $0.04).

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-video-13b-distilled` 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

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | Textaleiðbeiningar sem stýra efnisgerð. |
| `negative_prompt` |  | string | no | `worst quality, inconsistent motion, blurry, jittery, distorted` |  | Neikvæðar textaleiðbeiningar fyrir efnisgerð. |
| `loras` |  | array of object {path, weight_name, scale} | no | `[]` |  | LoRA-vigtir sem notaðar eru við efnisgerð. |
| `loras[].path` |  | string | yes |  |  | Staðsetning LoRA-vigtanna, gefin upp sem URL eða slóð. |
| `loras[].weight_name` |  | string \| null | no |  |  | Heiti LoRA-vigtar til að velja milli margra vigta í HuggingFace-geymslu; aðeins geymslur með mörgum vigtum þurfa þetta. Þessi stilling hefur engin áhrif nema `path` auðkenni HuggingFace-geymslu. |
| `loras[].scale` |  | number | no | `1` | 0 – 4 | Margfaldari sem skalar LoRA-vigtina þegar hún er hlaðin. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Upplausn úttaksmyndbandsins. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `9:16`, `1:1`, `16:9` | Myndhlutfall myndbandsins sem verður til. |
| `seed` |  | integer \| null | no |  |  | Frægildi sem stýrir slembni við efnisgerð. |
| `num_frames` |  | integer | no | `121` | 9 – 1,441 | Heildarfjöldi ramma í myndbandinu. |

| `second_pass_skip_initial_steps` |  | integer | no | `5` | 1 – 11 | Upphaflegur fjöldi ályktunarskrefa sem sleppa á í annarri umferð og beina henni að smáatriðavinnu fremur en stórfelldum breytingum. |
| `frame_rate` |  | integer | no | `24` | 1 – 60 | Rammatíðni myndbandsins. |
| `expand_prompt` |  | boolean | no | `false` |  | Stækkun kvaðningar með mállíkani. |
| `reverse_video` |  | boolean | no | `false` |  | Snúningur spilunarröð myndbandsins við. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Öryggisathugunarrofi þar sem slökkt stilling er aðeins virt fyrir heimilaða reikninga. Allar beiðnir án þeirrar heimildar fara í öryggisathugun. |
| `enable_detail_pass` |  | boolean | no | `false` |  | Valfrjáls önnur betrumbótaumferð sem bætir smáatriði myndbands þegar hún er virkjuð. |

Hún vinnur á mynduðum hlutum nema þeim fyrsta og staðlar litadreifingu í öllu myndbandinu til að vinna gegn stigvaxandi aukningu á mettunarstigi eða birtuskilum. |
| `tone_map_compression_ratio` |  | number | no | `0` | 0 – 1 | Þjöppunarstig tónvörpunar, frá engri þjöppun við 0.0 til hámarksþjöppunar við 1.0. Þjöppun hreyfisviðs myndbandsins með þessum hætti bætir sjónræn gæði. |

## Example input

Required parameters only:

  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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-video-13b-distilled?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"
  }'

# 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

```javascript
const API = "https://api.doitong.com/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/ltx-video-13b-distilled?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/ltx-video-13b-distilled", 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.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-video-13b-distilled",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.

Close-up on the van's tires shows the gravel spraying, highlighting the speed and rugged terrain. Sunlight filters through the trees, casting dappled shadows on the van and the trail.
