# Ltx 2.3 Quality · Decompression API

> Videon palautustehoste, joka vähentää pakkausartefakteja ja kohinaa leikkeessä

Käsittelee `video_url`-osoitteesta tulevan pakatun, artefakteja sisältävän videon ja tuottaa puhtaamman version. Lisää lyhyt kohtausta kuvaava `prompt`, jos haluat ohjata tulosta. Valitse 480p- tai 720p-tuloste; 720p sisältää noin 6 sekuntia ja 480p noin 15 sekuntia. `num_frames` hyväksyy arvot 9–481, ja `generate_audio` määrittää, säilyttääkö tulos ääniraidan.

## Pricing

Price: **$0.00241 / megapixel of output video**. Price per megapixel 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 $0.27 = 270 API credits (112 MP output video × $0.002408).

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-2.3-quality/decompression` 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 |
|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | Muunnoksen lähdevideon yksilöivä URL-osoite. |
| `prompt` |  | string | no | `` |  | Valinnainen lyhyt kohtauksen tai sisällön kuvaus, joka korvaa tyhjänä käytettävän yleisen kuvauksen. Tuloksen tarkentamiseksi annettu teksti sisällytetään kuvatekstiin, jolla efekti koulutettiin. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Valitse lyhyen sivun resoluutio säilyttäen lähteen kuvasuhde: 480p tuottaa pehmeämmän tuloksen enintään noin 15 sekunnin leikkeille, kun taas 720p tuottaa terävämmän tuloksen enintään noin 6 sekunnin leikkeille. Valitse pidemmille leikkeille 480p, koska IC-LoRA-ohjauspolku rajoittaa resoluution ja ruutujen määrän tuloa; rajan ylittävät pyynnöt hylätään selkeällä virheellä. Laske tulosteen kesto muodossa `num_frames` / `frames_per_second`. |
| `num_frames` |  | integer | no | `121` | 9 – 481 | Tulosteen ruutujen määrä, jota rajoittaa resoluution ja ruutujen tuloon perustuva IC-LoRA-budjetti: noin 6 sekuntia 720p-tasolla tai 15 sekuntia 480p-tasolla. Budjetin ylitys palauttaa virheen 422; pienennä arvoa `num_frames` tai valitse 480p. Leikkeen kesto sekunteina on `num_frames` / `frames_per_second`. |
| `frames_per_second` |  | number | no | `24` | 1 – 60 | Tulostevideon ruutunopeus ruutuina sekunnissa. |
| `num_inference_steps` |  | integer | no | `15` | 8 – 30 | Määritä suoritettavien päättelyvaiheiden määrä, enintään 30; muuttamatta jätettynä käytetään arvoa 15. |
| `guidance_scale` |  | number | no | `1` | 1 – 20 | Säädä classifier-free guidance -ohjausta tällä asteikolla; oletus on viritetty sekä korkeaan laatuun että nopeaan generointiin. |
| `generate_audio` |  | boolean | no | `true` |  | Palautettavan MP4-tiedoston ääniraidan valitsin: poissa käytöstä tuottaa vain videon sisältävän tiedoston, käytössä sisältää äänen. |
| `negative_prompt` |  | string | no | `color distortion, overexposure, static, blurry details, subtitles, style, artwork, painting, frame, still, dim overall tone, worst quality, low quality, JPEG compression artifacts, ugly, mutilated, extra fingers, poorly drawn hands, poorly drawn face, deformed, disfigured, malformed limbs, fused fingers, motionless frame, cluttered background, three legs, crowded background, walking backwards` |  | Negatiivinen kehote, joka määrittää, mitä generoinnissa tulee välttää. |
| `seed` |  | integer \| null | no |  |  | Generoinnin toistettavaksi tekevä siemen. Arvon None asettaminen valitsee siemenen satunnaisesti. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Määrittää, onko turvallisuustarkistus käytössä. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Tulostevideoon käytettävä laatu-esiasetus. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Tuloksena syntyvän videon kirjoitustila. |

File parameters (`video`) 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
{
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

A fuller example:

```json
{
  "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

## 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-2.3-quality/decompression?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }'

# 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-2.3-quality/decompression?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }),
});
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 = {
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/ltx-2.3-quality/decompression", 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-2.3-quality/decompression",
      "input": {
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
      },
      "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.
