# Wan-2.2 Text-to-Video A14B API

> A14B text-to-video mat 480p bis 720p Output, zwou Guidance-Etappen an optionaler Interpolatioun

Generéiert e Video aus engem Text-`prompt`. `num_frames` geet vun 17 bis 161, `frames_per_second` vun 4 bis 60, an `resolution` ass 480p, 580p oder 720p an 16:9, 9:16 oder 1:1. Zwou Guidance-Wäerter, eng `acceleration`-Astellung an film- oder rife-Interpolatioun (standardméisseg ee interpoléierte Frame) si verfügbar.

- 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 |  |  | Textinstruktiounen, déi d'Video-Generatioun steieren. |
| `negative_prompt` |  | string | no | `` |  | Negative Prompt bei der Generatioun vun engem Video. |
| `num_frames` |  | integer | no | `81` | 17 – 161 | Framezuel fir d'Generatioun, am inklusiven Beräich vun 17–161. |
| `frames_per_second` |  | integer \| null | no | `16` | 4 – 60 | Frame-Rate vum generéierte Video, mat Wäerter vun 4 bis 60; d'Astellung `adjust_fps_for_interpolation` op false behält dëse Rate onverännert. Bei Interpolatioun an `adjust_fps_for_interpolation` op true (Standard) multiplizéiert een dëse Rate mat 1 plus der Zuel vun interpoléierte Frames, fir den definitiven FPS ze kréien. Beispill: 16 FPS mat 1 interpoléierte Frame ginn 32 FPS. |
| `seed` |  | integer \| null | no |  |  | Seed, deen d'Generatioun reproduzéierbar mécht. Wann et op None gesat gëtt, gëtt e Seed zoufälleg gewielt. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `580p`, `720p` | Opléisung vum Output-Video: 480p, 580p oder 720p. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `9:16`, `1:1` | Aspektverhältnis vum Output-Video, entweder 16:9 oder 9:16. |
| `num_inference_steps` |  | integer | no | `27` | 2 – 40 | Unzuel vun de Sampling-Schrëtt; méi Schrëtt bedeite méi laang Veraarbechtung, awer besser Qualitéit. |
| `enable_safety_checker` |  | boolean | no | `false` |  | Input-Sécherheetskontroll virun der Veraarbechtung, déi nëmmen autoriséiert Konten ausschalte kënnen. Ufroen ouni Autorisatioun ginn ëmmer kontrolléiert; soss aktivéiert true d'Kontroll. |
| `enable_output_safety_checker` |  | boolean | no | `false` |  | Steiert d'Sécherheetskontroll vum generéierte Video; true aktivéiert eng Kontroll no der Generatioun. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Erlaabt engem Large Language Modell, de Prompt mat Detailer unzereecheren. Dës Erweiderung léisst d'Bedeitung vum Prompt onverännert. |
| `acceleration` |  | enum (string) | no | `regular` | `none`, `regular` | Beschleunegungsastellung, mat 'regular' als recommandéierter Wiel. Méi Beschleunegung reduzéiert d'Qualitéit, fir d'Generatiounszäit ze verkierzen. |
| `guidance_scale` |  | number | no | `3.5` | 1 – 10 | Classifier-free Guidance-Stäerkt; mat steigender Skala gëtt méigleche Qualitéitsverloscht géint eng méi genee Prompt-Entspriechung ofgewiicht. |
| `guidance_scale_2` |  | number | no | `4` | 1 – 10 | Guidance-Skala, déi steiert, wéi genee de Modell dem Prompt an der zweeter Etapp follegt. |
| `shift` |  | number | no | `5` | 1 – 10 | Video-Shift-Astellung mat engem erlaabte Beräich vun 1.0–10.0. |
| `interpolator_model` |  | enum (string) | no | `film` | `none`, `film`, `rife` | Frame-Interpolatiounsastellung: wielt None, fir d'Interpolatioun ze iwwersprangen, oder gitt de Modell un, deen se ausféiere soll. |
| `num_interpolated_frames` |  | integer | no | `1` | 0 – 4 | Setzt 0–4 interpoléiert Frames an all Lach tëscht zwee generéierte Frames an. |
| `adjust_fps_for_interpolation` |  | boolean | no | `true` |  | Schalter fir d'Frame-Rate-Adaptatioun: false behält den ugiwwene FPS, wärend true en duerch 1 plus d'Zuel vun interpoléierte Frames skaliéiert. Also ginn aus 16 FPS bei 1 interpoléierte Frame 32 FPS, wann d'Adaptatioun aktiv ass. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Qualitéitsastellung vum Output-Video, déi mat steigender Astellung méi grouss Dateien géint besser Visualiséierung tauscht. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Video-Schreifmodus, bei deem balanced e Kompromëss tëscht Geschwindegkeet a Qualitéit bitt. Wielt small fir déi klengst Dateien an déi luesst Schreifgeschwindegkeet; méi séiert Schreiwe liwwert Resultater éischter, erstellt awer méi grouss Dateien. |

## 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.
