# Ltx 2.3 Quality · Decompression API

> Athari ya kurejesha video inayopunguza kasoro za mgandamizo na kelele katika klipu

Huchakata video iliyobanwa yenye kasoro nyingi kutoka `video_url` ili kutoa toleo safi zaidi. Ongeza `prompt` fupi inayoeleza tukio ikiwa ungependa kuiongoza. Chagua tokeo la 480p au 720p; 720p inatoshea takriban sekunde 6 na 480p takriban sekunde 15. `num_frames` inakubali 9 hadi 481, na `generate_audio` hudhibiti kama tokeo linahifadhi rekodi ya sauti.

- Output: video
- Price per megapixel of your output video: $0.00241 / megapixel of output video (cheapest run $0.003 (3 API credits))
- Run: `POST https://api.doitong.ru/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.ru/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 inayotambua video chanzo kwa ajili ya mabadiliko. |
| `prompt` |  | string | no | `` |  | Maelezo mafupi ya hiari ya tukio au maudhui yanayochukua nafasi ya maelezo ya jumla yanapoachwa tupu. Ili kuboresha matokeo, maandishi yaliyotolewa hujumuishwa kwenye caption ambayo effect ilifunzwa kwayo. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Chagua mwonekano wa upande mfupi wa tokeo huku ukihifadhi uwiano wa kipengele wa chanzo: 480p hutoa matokeo laini zaidi kwa klipu za hadi takriban sekunde 15, huku 720p ikitoa matokeo makali zaidi kwa hadi takriban sekunde 6. Chagua 480p kwa klipu ndefu kwa sababu njia ya udhibiti ya IC-LoRA inaweka kikomo kwa mwonekano unaozidishwa kwa idadi ya fremu; maombi yanayozidi bajeti hiyo hukataliwa kwa hitilafu iliyo wazi. Kokotoa muda wa tokeo kama `num_frames` / `frames_per_second`. |
| `num_frames` |  | integer | no | `121` | 9 – 481 | Idadi ya fremu za tokeo, iliyo chini ya bajeti ya IC-LoRA ya mwonekano unaozidishwa kwa fremu: takriban sekunde 6 katika 720p au sekunde 15 katika 480p. Kuzidi bajeti hiyo hurudisha 422; punguza `num_frames` au chagua 480p. Muda wa klipu kwa sekunde ni sawa na `num_frames` / `frames_per_second`. |
| `frames_per_second` |  | number | no | `24` | 1 – 60 | Kiwango cha fremu za video ya tokeo, kinachopimwa kwa fremu kwa sekunde. |
| `num_inference_steps` |  | integer | no | `15` | 8 – 30 | Weka idadi ya hatua za inference za kuendesha, hadi 30; kuiacha bila kubadilishwa hutumia 15. |
| `guidance_scale` |  | number | no | `1` | 1 – 20 | Rekebisha mwongozo usio na classifier kwa kutumia kipimo hiki; urekebishaji wake chaguomsingi hulenga ubora wa juu na uzalishaji wa haraka. |
| `generate_audio` |  | boolean | no | `true` |  | Kigeuzi cha wimbo wa sauti kwa MP4 inayorejeshwa: ikiwa kimezimwa hutengeneza faili ya video pekee, na kikiwa kimewashwa hujumuisha sauti. |
| `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` |  | Kidokezo hasi kinachobainisha kile ambacho uzalishaji unapaswa kuepuka. |
| `seed` |  | integer \| null | no |  |  | Seed inayofanya uzalishaji uweze kurudiwa. Kuiweka kuwa None huchagua seed bila mpangilio. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Hudhibiti ikiwa ukaguzi wa usalama umewashwa. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Preset ya ubora inayotumika kwenye video ya tokeo. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Hali ya kuandika ya video inayotokana. |

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.ru/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.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/ltx-2.3-quality/decompression?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({

  }),
});
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 = {
    "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.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": "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.
