# Wan VACE Video Edit API

> Hubadilisha video iliyopo kwa maagizo ya lugha rahisi, ikiwa na picha za marejeo za hiari

Hupokea agizo la `prompt` na `video_url`, kisha hurudisha video iliyohaririwa. `video_type` inaweza kuwa auto, general au human, ya mwisho ikiwa kwa video inayolenga watu. Picha za marejeleo huwekwa kwenye `image_urls`. Uwiano wa pande na `resolution` (240p hadi 720p) vinaweza kuwekwa, na upunguzaji wa sampuli kiotomatiki husaidia kwa ingizo refu au lenye kasi kubwa ya fremu.

- Model id: `wan-vace-apps/video-edit`
- Made by: Alibaba
- Category: Video to Video
- Output: video
- Price per second of your input video: from $0.05 / second of input video (cheapest run $0.05 (50 API credits))
- Run: `POST https://api.doitong.com/v1/run/wan-vace-apps/video-edit`
- Quote: `POST https://api.doitong.com/v1/quote/wan-vace-apps/video-edit`
- Docs page: https://doitong.com/sw/developers/models/wan-vace-apps/video-edit

## Pricing

Price: **from $0.05 / second of input video** (the lowest tier; the quote prices your exact input). Price per second of your input 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:

- 240p: $0.05 / second of input video
- 360p: $0.05 / second of input video
- 480p: $0.05 / second of input video
- 580p: $0.075 / second of input video
- auto: $0.10 / second of input video
- 720p: $0.10 / second of input video

The full example input below costs $1.875 = 1875 API credits (18.75 s input video × $0.10 (auto)).

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/wan-vace-apps/video-edit` 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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | Kidokezo kinachobainisha mabadiliko ya video. |
| `video_url` | `video` | string (video URL) | yes |  |  | URL ya video ya ingizo. |
| `video_type` |  | enum (string) | no | `auto` | `auto`, `general`, `human` | Aina ya video ya ingizo kwa uhariri, inayokadiriwa kutoka fremu ya kwanza ikiwa itaachwa kwenye chaguo chaguomsingi 'auto'. Chagua 'human' kwa kuzingatia watu na mienendo yao, au 'general' kwa video nyingine nyingi. |
| `image_urls` | `images` | array of image URL | no | `[]` |  | URL za picha za ingizo zinazotoa marejeleo ya picha kwa uzalishaji. |
| `resolution` |  | enum (string) | no | `auto` | `auto`, `240p`, `360p`, `480p`, `580p`, `720p` | Mwonekano wa tokeo baada ya kuhariri. |
| `acceleration` |  | enum (string) \| null | no | `regular` | `none`, `low`, `regular` | Mpangilio wa kuharakisha inference, ukiwa na chaguo la 'none' au 'regular': uchakataji ulioharakishwa huongeza kasi kwa kiasi kikubwa kwa gharama ya mabadiliko madogo sana ya tokeo. |
| `enable_auto_downsample` |  | boolean | no | `true` |  | Washa kupunguza sampuli ili kuruhusu mfuatano mrefu zaidi unaozalishwa wakati wa kuchakata video ndefu au video zenye kasi kubwa za fremu. Upunguzaji hufanyika kiotomatiki, na interpolation baada ya uzalishaji hurejesha kasi ya awali ya fremu. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `16:9`, `9:16`, `1:1` | Uwiano wa upana kwa urefu wa video iliyohaririwa. |
| `auto_downsample_min_fps` |  | number | no | `15` | 1 – 60 | Kasi ya chini kabisa ya fremu inayolengwa, kwa fremu kwa sekunde, kwa ajili ya kupunguza sampuli ya video. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Hudhibiti ikiwa ukaguzi wa usalama umewashwa. |
| `return_frames_zip` |  | boolean | no | `false` |  | Hudhibiti ikiwa fremu zote zilizozalishwa pia zitawekwa kwenye hifadhi ya ZIP. |

File parameters (`video`, `images`) 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
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "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/wan-vace-apps/video-edit?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
    "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

```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
    "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/wan-vace-apps/video-edit", 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": "wan-vace-apps/video-edit",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "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.
