# Ltx 2.3 Quality · Decompression API

> Video atjaunošanas efekts, kas samazina saspiešanas artefaktus un troksni klipā

Apstrādā saspiestu video ar daudziem artefaktiem no `video_url`, lai izveidotu tīrāku versiju. Ja vēlaties vadīt rezultātu, pievienojiet īsu ainu aprakstošu `prompt`. Izvēlieties 480p vai 720p izvadi; 720p ietilpina aptuveni 6 sekundes, bet 480p — aptuveni 15 sekundes. `num_frames` pieņem vērtības no 9 līdz 481, bet `generate_audio` nosaka, vai rezultāts saglabā audio celiņu.

- Run: `POST https://api.doitong.com/v1/run/ltx-2.3-quality/decompression`

## 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 |  |  | URL, kas identificē avota video pārveidošanai. |
| `prompt` |  | string | no | `` |  | Neobligāts īss ainas vai satura apraksts, kas aizstāj vispārīgo aprakstu, ja šis lauks ir tukšs. Lai rezultāts būtu precīzāks, norādītais teksts tiek iekļauts parakstā, pēc kura efekts tika apmācīts. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Izvēlieties īsākās malas izšķirtspēju, saglabājot avota malu attiecību: 480p nodrošina maigākus rezultātus klipiem līdz aptuveni 15 sekundēm, bet 720p — asākus rezultātus līdz aptuveni 6 sekundēm. Garākiem klipiem izvēlieties 480p, jo IC-LoRA vadības ceļš ierobežo izšķirtspējas un kadru skaita reizinājumu; pieprasījumi, kas pārsniedz šo budžetu, tiek noraidīti ar skaidru kļūdu. Aprēķiniet izvades ilgumu kā `num_frames` / `frames_per_second`. |
| `num_frames` |  | integer | no | `121` | 9 – 481 | Izvades kadru skaits, uz kuru attiecas IC-LoRA budžets, kas ierobežo izšķirtspējas un kadru skaita reizinājumu: aptuveni 6 sekundes pie 720p vai 15 sekundes pie 480p. Budžeta pārsniegšana atgriež 422; samaziniet `num_frames` vai atlasiet 480p. Klipa ilgums sekundēs ir `num_frames` / `frames_per_second`. |
| `frames_per_second` |  | number | no | `24` | 1 – 60 | Izvades video kadru ātrums, mērīts kadros sekundē. |
| `num_inference_steps` |  | integer | no | `15` | 8 – 30 | Iestatiet izpildāmo secināšanas soļu skaitu, nepārsniedzot 30; nemainot šo vērtību, tiek izmantoti 15. |
| `guidance_scale` |  | number | no | `1` | 1 – 20 | Pielāgojiet classifier-free guidance, izmantojot šo mērogu; tā noklusējuma regulējums ir paredzēts augstai kvalitātei un ātrai ģenerēšanai. |
| `generate_audio` |  | boolean | no | `true` |  | Atgrieztā MP4 audio celiņa pārslēgs: izslēgts izveido tikai video failu, bet ieslēgts ietver audio. |
| `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` |  | Negatīvā uzvedne, kas norāda, no kā ģenerēšanā jāizvairās. |
| `seed` |  | integer \| null | no |  |  | Sēkla, kas padara ģenerēšanu atkārtojamu. Iestatot None, sēkla tiek izvēlēta nejauši. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Nosaka, vai drošības pārbaude ir iespējota. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Izvades video pielietotais kvalitātes iestatījums. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Iegūtā video ierakstīšanas režīms. |

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

}
```

## 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.
