# Lightx · Recamera API

> Filma da nov in video existent cun in nov traject da camera e nova illuminaziun, cun controlla dal traject u da la posa finala

Prenda in `video_url` d’entrada e al renda da nov cun ina perspectiva da camera midada. Mette `camera` a `traj` e furnescha ina `trajectory`, u a `target` e inditga ina `target_pose` da [theta, phi, radius, x, y]. Il `mode` dal moviment po esser gradual, bullet, direct u dolly-zoom. In `prompt` da text è facultativ; sch’el manca, il video vegn intitulà automaticamain.

- Model id: `lightx/recamera`
- Made by: Open model
- Category: Video to Video
- Output: video
- Price per second of your output video: $0.10 / second of output video (cheapest run $0.10 (100 API credits))
- Run: `POST https://api.doitong.ru/v1/run/lightx/recamera`
- Quote: `POST https://api.doitong.ru/v1/quote/lightx/recamera`
- Docs page: https://doitong.com/rm/developers/models/lightx/recamera

## Pricing

Price: **$0.10 / second of output video**. 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 $0.49 = 490 API credits (4.9 s output video × $0.10).

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/lightx/recamera` 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 dal video d'input. |
| `prompt` |  | string \| null | no |  |  | Prompt da text opzional; Light-X titulescha automaticamain il video sch'i na vegn furnì nagin prompt. |
| `seed` |  | integer \| null | no |  |  | Seed che renda la generaziun reproducibla. Cun definir None vegn tschernì in seed casualmain. |
| `camera` |  | enum (string) | no | `traj` | `traj`, `target` | Mod utilisà per controllar la camera. |
| `mode` |  | enum (string) | no | `gradual` | `gradual`, `bullet`, `direct`, `dolly-zoom` | Mod utilisà per il moviment da camera. |
| `trajectory` |  | object {theta, phi, radius} \| null | no |  |  | Configuraziuns dal traject da camera, necessarias en il mod recamera. |
| `trajectory.theta` |  | array of number | yes |  |  | Anguls da rotaziun orizontals per keyframe, mesirads en grads. |
| `trajectory.phi` |  | array of number | yes |  |  | Anguls da rotaziun verticals per keyframe, mesirads en grads. |
| `trajectory.radius` |  | array of number | yes |  |  | Facturs per keyframe che scalassan la distanza da la camera. |
| `target_pose` |  | array of number \| null | no |  |  | Posa da mira da la camera, necessaria sche camera='target'. Furnescha in array ordinà sco theta, lura phi, lura radius, lura x, lura y. |
| `enable_safety_checker` |  | boolean | no | `true` |  | La controlla po vegnir schluccada cun definir false, premess che l'appelant saja autorisà. |

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/lightx/recamera?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/lightx/recamera?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.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/lightx/recamera", 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": "lightx/recamera",
      "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.
