# Wan · v2.2 A14b · Video to Video API

> Bhidio-gu-bhidio A14B a bhios ag ath-stoidhleadh criomag tùsail bho prompt le neart a ghabhas atharrachadh

Atharraichidh e `video_url` cuir-a-steach a rèir `prompt`. Suidhichidh `strength` bho 0 gu 1 dè cho fada ’s a dh’fhalbhas an toradh bhon tùs: cumaidh 0 an cuir-a-steach, agus leanaidh 1 am prompt gu h-iomlan. Tha an co-mheas taobh auto a ghnàth agus a’ maidseadh a’ chuir-a-steach. Tha an rùn 480p gu 720p, `num_frames` 17 gu 161, agus faodaidh `resample_fps` am bhidio ath-shamplachadh.

- Model id: `wan/v2.2-a14b/video-to-video`
- Made by: Alibaba
- Category: Video to Video
- Output: video
- Price per second of your output video: from $0.04 / second of output video (cheapest run $0.04 (40 API credits))
- Run: `POST https://api.doitong.ru/v1/run/wan/v2.2-a14b/video-to-video`
- Quote: `POST https://api.doitong.ru/v1/quote/wan/v2.2-a14b/video-to-video`
- Docs page: https://doitong.com/gd/developers/models/wan/v2.2-a14b/video-to-video

## Pricing

Price: **from $0.04 / second of output video** (the lowest tier; the quote prices your exact input). 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.

Price by tier:

- 480p: $0.04 / second of output video
- 360p: $0.04 / second of output video
- 240p: $0.04 / second of output video
- 580p: $0.06 / second of output video
- 720p: $0.08 / second of output video
- auto: $0.08 / second of output video

The full example input below costs $0.81 = 810 API credits (10.125 s output video × $0.08 (720p)).

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/wan/v2.2-a14b/video-to-video` 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.

Tagh small airson na faidhlichean as lugha agus an sgrìobhadh as slaodaiche; bidh sgrìobhadh nas luaithe a’ tilleadh thoraidhean nas luaithe ach a’ cruthachadh faidhlichean nas motha. |
| `resample_fps` |  | boolean | no | `false` |  | Co-dhiù a tha ath-shamplachadh bhidio à comas (false) no air a dhèanamh aig an ìre frèamaichean a chaidh a thoirt seachad (true). |

## 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/wan/v2.2-a14b/video-to-video?wait=20" \

### 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": "wan/v2.2-a14b/video-to-video",
      "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.
