# Wan-2.2 Text-to-Video A14B API

> Maandishi-hadi-video ya A14B yenye tokeo la 480p hadi 720p, hatua mbili za mwongozo na interpolation ya hiari

Huzalisha video kutoka kwenye `prompt` ya maandishi. `num_frames` huanzia 17 hadi 161, `frames_per_second` kutoka 4 hadi 60, na `resolution` ni 480p, 580p au 720p katika 16:9, 9:16 au 1:1. Thamani mbili za guidance, mpangilio wa `acceleration` na interpolation ya film au rife (fremu moja kwa chaguo-msingi) zinapatikana.

- 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`
- Docs page: https://doitong.com/sw/developers/models/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 |  |  | Maelekezo ya maandishi yanayoongoza uzalishaji wa video. |
| `negative_prompt` |  | string | no | `` |  | Kidokezo hasi kinachotumika wakati wa kutengeneza video. |
| `num_frames` |  | integer | no | `81` | 17 – 161 | Idadi ya fremu za uzalishaji, yenye masafa jumuishi ya 17–161. |
| `frames_per_second` |  | integer \| null | no | `16` | 4 – 60 | Kasi ya fremu za video iliyozalishwa, inayokubali thamani kutoka 4 hadi 60; kuweka `adjust_fps_for_interpolation` kuwa false huhifadhi kasi hii bila mabadiliko. Interpolation inapotumika na `adjust_fps_for_interpolation` ikiwa true (chaguo lake chaguomsingi), zidisha kasi hii kwa moja pamoja na idadi ya fremu zilizointerpolatiwa ili kupata FPS ya mwisho. Kwa mfano, 16 FPS yenye fremu 1 iliyointerpolatiwa huwa 32 FPS. |
| `seed` |  | integer \| null | no |  |  | Seed inayofanya uzalishaji uweze kurudiwa. Kuiweka kuwa None huchagua seed bila mpangilio. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `580p`, `720p` | Mwonekano wa video ya tokeo: 480p, 580p au 720p. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `9:16`, `1:1` | Uwiano wa video ya tokeo, ama 16:9 au 9:16. |
| `num_inference_steps` |  | integer | no | `27` | 2 – 40 | Idadi ya hatua za sampuli, ambapo muda mrefu wa uchakataji huleta ubora bora kadiri idadi inavyoongezeka. |
| `enable_safety_checker` |  | boolean | no | `false` |  | Ukaguzi wa usalama wa ingizo kabla ya uchakataji, ambao ni akaunti zilizoidhinishwa pekee zinazoweza kuuzima. Maombi yasiyo na idhini hukaguliwa kila mara; vinginevyo, true huwezesha ukaguzi. |
| `enable_output_safety_checker` |  | boolean | no | `false` |  | Hudhibiti ukaguzi wa usalama wa video iliyozalishwa; kuweka true huwezesha ukaguzi baada ya uzalishaji. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Ruhusu modeli kubwa ya lugha kuimarisha kidokezo kwa maelezo. Kuwasha upanuzi huu hakubadilishi maana ya kidokezo. |
| `acceleration` |  | enum (string) | no | `regular` | `none`, `regular` | Mpangilio wa kuongeza kasi, ambapo 'regular' ndiyo chaguo linalopendekezwa. Kuongeza kasi hupunguza ubora ili kufupisha muda wa uzalishaji. |
| `guidance_scale` |  | number | no | `3.5` | 1 – 10 | Nguvu ya mwongozo isiyotegemea kiainishaji, ambapo ongezeko la kipimo hubadilisha uwezekano wa kupoteza ubora kwa ulinganifu wa karibu zaidi na kidokezo. |
| `guidance_scale_2` |  | number | no | `4` | 1 – 10 | Mizani ya mwongozo inayodhibiti jinsi modeli inavyofuata kidokezo katika hatua yake ya pili. |
| `shift` |  | number | no | `5` | 1 – 10 | Mpangilio wa mgeuzo wa video, wenye masafa yanayoruhusiwa ya 1.0–10.0. |
| `interpolator_model` |  | enum (string) | no | `film` | `none`, `film`, `rife` | Mpangilio wa interpolation ya fremu: chagua None kuruka interpolation, au bainisha modeli ya kuitekeleza. |
| `num_interpolated_frames` |  | integer | no | `1` | 0 – 4 | Weka fremu 0–4 zilizointerpolatiwa katika kila pengo kati ya fremu mbili zilizozalishwa. |
| `adjust_fps_for_interpolation` |  | boolean | no | `true` |  | Kigeuzi cha kurekebisha kasi ya fremu: false huhifadhi FPS iliyotolewa, ilhali true huizidisha kwa moja pamoja na idadi ya fremu zilizointerpolatiwa. Hivyo, 16 FPS huwa 32 FPS wakati fremu 1 imeinterpolatiwa na urekebishaji umewezeshwa. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Mpangilio wa ubora wa video ya tokeo unaobadilisha ukubwa wa faili kwa picha bora zaidi kadiri thamani inavyoongezeka. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Hali ya kuandika video, ambapo balanced hutoa uwiano kati ya kasi na ubora. Chagua small kwa faili ndogo zaidi na uandishi wa polepole zaidi; uandishi wa haraka hurudisha matokeo mapema lakini huunda faili kubwa zaidi. |

## 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" \

  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/v1";

### 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.
