# Ltx 2.3 Quality · Render to Real API

> Ka huri i ngā whakaahua render 3D, CG, kēmu rānei hei ataata tino rite ki te ao, me te kaha kōwhiri

Ka hurihia tētahi whakaputa 3D i tukuna hei `video_url` kia tino tūturu ake te āhua. Ka taea `intensity` te light, strong, strong-v2 rānei, mai i te māmā ki te kaha. Mā te `image_url` kōwhiringa e tautuhi te anga tuatahi whakaahua-tūturu, ā, mā `enable_detail_refine` e tāpiri he tukanga whakakoi tuarua me `detail_refine_strength` mai i te 0.3 ki te 0.95. Ka puritia te keu `3DREAL` i roto i te tohutohu, ā, ko te putanga 480p, 720p rānei.

- Model id: `ltx-2.3-quality/render-to-real`
- Made by: Lightricks
- Category: Video to Video
- Output: video
- Price per megapixel of your output video: from $0.00241 / megapixel of output video (cheapest run $0.003 (3 API credits))
- Run: `POST https://api.doitong.com/v1/run/ltx-2.3-quality/render-to-real`
- Quote: `POST https://api.doitong.com/v1/quote/ltx-2.3-quality/render-to-real`
- Docs page: https://doitong.com/mi/developers/models/ltx-2.3-quality/render-to-real

## Pricing

Price: **from $0.00241 / megapixel of output video** (the lowest tier; the quote prices your exact input). 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.

Price by tier:

- base rate: $0.00241 / megapixel of output video
- detail refine: $0.00963 / megapixel of output video

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/render-to-real` 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 |  |  | He URL e tohu ana ki tētahi ataata 3D, CG, kēmu rānei kua tāia, hei panoni whakaahua-tūturu. |
| `image_url` | `image` | string (image URL) \| null | no |  |  | He here atahanga kōwhiringa mō te anga 0, hei whakatū i tōna āhua whakaahua-tūturu. Ki te kore, ko te tānga anake hei ārahi i te putanga; ina tukuna, ka noho te atahanga hei anga tuatahi, kia rite ki te whakangungu atahanga-ki-te-ataata a te pūurutau. |
| `intensity` |  | enum (string) | no | `light` | `light`, `strong`, `strong-v2` | Te taumata panoni whakaahua-tūturu, ko `strong-v2` te tohu i te pūurutau hou kua whakapai ake mō te pai ake o te hononga i waenga i ngā whakaaturanga, te ororongo, ngā kiripuaki kōrero, me te kounga whānui. Mō ērā atu kōwhiringa, kōwhiria `light` kia nui ake te pupuri i te āhua me te nekehanga o te tānga pūtake, ko `strong` rānei mō ngā panoni kaha ake ki te whakaahua-tūturu. |
| `enable_detail_refine` |  | boolean | no | `false` |  | Ka whakakā i tētahi wāhanga whakapai anō hei whakapiki i te koi me te taumira; he mea whakaweto taunoa. Whai muri i te whakaputanga taketake, ka whakanuia e tētahi kaiwhakanuia ā-wāhi te latent ataata kia 2x, kātahi ka whakapaihia e tētahi wāhanga taipitopito poto mā te tauira kua whakarewaina. |

Kōwhiria te 480p mō ngā topenga roa ake nā te mea ka whakawhāiti te ara whakahaere IC-LoRA i te taumira whakareatia ki te tatau anga; ka whakahokia ngā tono ka hipa i taua pūtea me tētahi hapa mārama. Tātaihia te roanga putanga hei `num_frames` / `frames_per_second`. |

Mā te hipa i taua pūtea ka whakahoki 422; whakaitia `num_frames`, kōwhiria rānei te 480p. Ko te roanga topenga i ngā hēkona he `num_frames` / `frames_per_second`. |
| `frames_per_second` |  | number | no | `24` | 1 – 60 | Tere anga ataata putanga, ka inehia ki ngā anga ia hēkona. |
| `num_inference_steps` |  | integer | no | `15` | 8 – 30 | Tautuhia te maha o ngā hīkoi inference hei whakahaere, tae atu ki te 30; ki te waiho kia kore e whakarerekēhia, ka whakamahia te 15. |

}
```

A fuller example:

## 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/render-to-real?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/render-to-real?wait=20", {
  method: "POST",
  headers,

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",

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/render-to-real",
      "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.
