# Lightx · Recamera API

> פֿילמט איבער אַן עקזיסטירנדיקן ווידעא פֿון אַ נײַער קאַמערע-וועג, מיט באַלויכטונג-ענדערונג, ניצנדיק טראַיעקטאָריע אָדער target-pose קאָנטראָל

נעמט אַן אַרײַנגעגעבענעם `video_url` און רענדערט אים ווידער מיט אַ געביטן קאַמערע-קוקווינקל. שטעלט `camera` אויף `traj` און גיט אַ `trajectory`, אָדער אויף `target` און גיט אַ `target_pose` פֿון [theta, phi, radius, x, y]. דער באַוועגונג `mode` קען זײַן gradual, bullet, direct אָדער dolly-zoom. אַ טעקסט `prompt` איז אָפּציאָנעל; אויב מען לאָזט עס אויס, ווערט דער ווידעא אויטאָמאַטיש באַשריבן.

- 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.com/v1/run/lightx/recamera`
- Quote: `POST https://api.doitong.com/v1/quote/lightx/recamera`
- Docs page: https://doitong.com/yi/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.com/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 פון דער אַרײַנגעבונג־ווידעא. |
| `prompt` |  | string \| null | no |  |  | אָפּציאָנאַלע טעקסט־פּראָמפּט; Light-X קעפּלט אויטאָמאַטיש דעם ווידעא ווען קיין פּראָמפּט איז נישט צוגעשטעלט. |
| `seed` |  | integer \| null | no |  |  | סיד וואָס מאכט גענערירונג רעפּראָדוצירבאַר. אויב מען שטעלט עס אויף None, ווערט אַ סיד ראַנדאָם אויסגעקליבן. |
| `camera` |  | enum (string) | no | `traj` | `traj`, `target` | מאָדע גענוצט צו קאָנטראָלירן די קאַמעראַ. |
| `mode` |  | enum (string) | no | `gradual` | `gradual`, `bullet`, `direct`, `dolly-zoom` | מאָדע גענוצט פֿאַר קאַמעראַ־באַוועגונג. |
| `trajectory` |  | object {theta, phi, radius} \| null | no |  |  | קאַמעראַ־וועג־באַשטעטיקונגען, נייטיק אין recamera־מאָדע. |
| `trajectory.theta` |  | array of number | yes |  |  | האָריזאָנטאַלע ראָוטאַציע־ווינקלען פֿאַר יעדן keyframe, געמאסטן אין גראַדן. |
| `trajectory.phi` |  | array of number | yes |  |  | ווערטיקאַלע ראָוטאַציע־ווינקלען פֿאַר יעדן keyframe, געמאסטן אין גראַדן. |
| `trajectory.radius` |  | array of number | yes |  |  | פֿאַקטאָרן פֿאַר יעדן keyframe וואָס סקיילען די קאַמעראַ־דיסטאַנץ. |
| `target_pose` |  | array of number \| null | no |  |  | ציל־פּאָזע פֿון קאַמעראַ, נייטיק ווען camera='target'. צושטעלט אַן array אין דער אָרדענונג theta, דערנאָך phi, דערנאָך radius, דערנאָך x, דערנאָך y. |
| `enable_safety_checker` |  | boolean | no | `true` |  | סקרינינג קען ווערן פאַרלייכטערט דורך שטעלן false, אויב דער רופער איז אָטעריזירט. |

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/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.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/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.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/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.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": "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.
