# Wan-2.2 Text-to-Video A14B API

> Teks-ke-video A14B dengan output 480p hingga 720p, dua peringkat panduan dan interpolasi pilihan

Menjana video daripada `prompt` teks. `num_frames` berjulat 17 hingga 161, `frames_per_second` daripada 4 hingga 60, dan `resolution` ialah 480p, 580p atau 720p dalam 16:9, 9:16 atau 1:1. Dua nilai guidance, tetapan `acceleration` serta interpolasi film atau rife (satu bingkai interpolasi secara lalai) tersedia.

- Model id: `wan/v2.2-a14b/text-to-video`
- Made by: Alibaba
- Category: Text 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/text-to-video`
- Quote: `POST https://api.doitong.ru/v1/quote/wan/v2.2-a14b/text-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
- 580p: $0.06 / second of output video
- 720p: $0.08 / second of output video

The full example input below costs $0.405 = 405 API credits (5.0625 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/text-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

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | Arahan teks yang memandu penjanaan video. |
| `negative_prompt` |  | string | no | `` |  | Prompt negatif yang digunakan semasa menjana video. |
| `num_frames` |  | integer | no | `81` | 17 – 161 | Bilangan bingkai untuk penjanaan, dengan julat inklusif 17–161. |
| `frames_per_second` |  | integer \| null | no | `16` | 4 – 60 | Kadar bingkai video yang dijana, menerima nilai dari 4 hingga 60; menetapkan `adjust_fps_for_interpolation` kepada false mengekalkan kadar ini tanpa perubahan. Dengan interpolasi dan `adjust_fps_for_interpolation` true (lalainya), darabkan kadar ini dengan satu tambah bilangan bingkai interpolasi untuk mendapatkan FPS akhir. Contohnya, 16 FPS dengan 1 bingkai interpolasi menjadi 32 FPS. |
| `seed` |  | integer \| null | no |  |  | Seed yang menjadikan penjanaan boleh diulang. Menetapkannya kepada None memilih seed secara rawak. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `580p`, `720p` | Resolusi video output: 480p, 580p atau 720p. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `9:16`, `1:1` | Nisbah aspek video output, sama ada 16:9 atau 9:16. |
| `num_inference_steps` |  | integer | no | `27` | 2 – 40 | Bilangan langkah pensampelan, yang menukar masa pemprosesan lebih lama dengan kualiti lebih baik apabila bilangannya meningkat. |
| `enable_safety_checker` |  | boolean | no | `false` |  | Pemeriksaan keselamatan input sebelum pemprosesan, yang hanya boleh dimatikan oleh akaun yang diberi kuasa. Permintaan tanpa kebenaran sentiasa diperiksa; jika tidak, true mendayakan pemeriksaan. |
| `enable_output_safety_checker` |  | boolean | no | `false` |  | Mengawal pemeriksaan keselamatan video yang dijana; menetapkan true mendayakan semakan selepas penjanaan. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Benarkan model bahasa besar memperkaya prompt dengan butiran. Mendayakan pengembangan ini mengekalkan maksud prompt. |
| `acceleration` |  | enum (string) | no | `regular` | `none`, `regular` | Tetapan pecutan, dengan 'regular' sebagai pilihan disyorkan. Pecutan lebih tinggi mengorbankan kualiti untuk memendekkan masa penjanaan. |
| `guidance_scale` |  | number | no | `3.5` | 1 – 10 | Kekuatan panduan tanpa pengelas, yang menukar kemungkinan kehilangan kualiti dengan padanan prompt yang lebih rapat apabila skala meningkat. |
| `guidance_scale_2` |  | number | no | `4` | 1 – 10 | Skala panduan yang mengawal sejauh mana model mengikuti prompt semasa peringkat keduanya. |
| `shift` |  | number | no | `5` | 1 – 10 | Tetapan anjakan video, dengan julat yang dibenarkan 1.0–10.0. |
| `interpolator_model` |  | enum (string) | no | `film` | `none`, `film`, `rife` | Tetapan interpolasi bingkai: pilih None untuk melangkau interpolasi, atau nyatakan model untuk melaksanakannya. |
| `num_interpolated_frames` |  | integer | no | `1` | 0 – 4 | Sisipkan 0–4 bingkai interpolasi ke dalam setiap ruang antara dua bingkai yang dijana. |
| `adjust_fps_for_interpolation` |  | boolean | no | `true` |  | Suis pelarasan kadar bingkai: false mengekalkan FPS yang dibekalkan, manakala true menskalakannya dengan satu tambah bilangan bingkai interpolasi. Oleh itu, 16 FPS menjadi 32 FPS apabila 1 bingkai diinterpolasi dan pelarasan didayakan. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Tetapan kualiti video output yang menukar saiz fail lebih besar untuk visual lebih baik apabila tetapan meningkat. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Mod penulisan video, dengan balanced menawarkan kompromi antara kelajuan dan kualiti. Pilih small untuk fail terkecil dan penulisan paling perlahan; penulisan lebih pantas mengembalikan hasil lebih awal tetapi menghasilkan fail lebih besar. |

## 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/text-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/text-to-video",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
