# Wan-2.2 Text-to-Video A14B API

> A14B text-to-video med output fra 480p til 720p, guidance i to trin og valgfri interpolation

Genererer en video fra en tekst-`prompt`. `num_frames` går fra 17 til 161, `frames_per_second` fra 4 til 60, og `resolution` er 480p, 580p eller 720p i 16:9, 9:16 eller 1:1. To guidance-værdier, en `acceleration`-indstilling samt film- eller rife-interpolation (én interpoleret frame som standard) er tilgængelige.

- 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 |  |  | Tekstinstruktioner, der styrer videogenerering. |
| `negative_prompt` |  | string | no | `` |  | Negativ prompt anvendt ved generering af en video. |
| `num_frames` |  | integer | no | `81` | 17 – 161 | Antal frames til generering med et inklusivt interval på 17–161. |
| `frames_per_second` |  | integer \| null | no | `16` | 4 – 60 | Den genererede videos billedhastighed, der accepterer værdier fra 4 til 60; indstilling af `adjust_fps_for_interpolation` til false bevarer denne hastighed uændret. Ved interpolation og `adjust_fps_for_interpolation` sat til true (standardværdien) ganges denne hastighed med én plus antallet af interpolerede frames for at beregne den endelige FPS. 16 FPS med 1 interpoleret frame bliver f.eks. til 32 FPS. |
| `seed` |  | integer \| null | no |  |  | Seed, der gør genereringen reproducerbar. Indstilling til None vælger en seed tilfældigt. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `580p`, `720p` | Outputvideoens opløsning: 480p, 580p eller 720p. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `9:16`, `1:1` | Outputvideoens størrelsesforhold, enten 16:9 eller 9:16. |
| `num_inference_steps` |  | integer | no | `27` | 2 – 40 | Antal samplingstrin, hvor længere behandlingstid byttes for bedre kvalitet, når antallet øges. |
| `enable_safety_checker` |  | boolean | no | `false` |  | Sikkerhedskontrol af input før behandling, som kun autoriserede konti kan deaktivere. Anmodninger uden autorisation kontrolleres altid; ellers aktiverer true kontrollen. |
| `enable_output_safety_checker` |  | boolean | no | `false` |  | Styrer sikkerhedskontrollen af den genererede video; true aktiverer en kontrol efter genereringen. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Tillad en stor sprogmodel at berige prompten med detaljer. Denne udvidelse ændrer ikke promptens betydning. |
| `acceleration` |  | enum (string) | no | `regular` | `none`, `regular` | Accelerationsindstilling, hvor 'regular' anbefales. Højere acceleration reducerer kvaliteten for at forkorte genereringstiden. |
| `guidance_scale` |  | number | no | `3.5` | 1 – 10 | Styrke for classifier-free guidance, hvor muligt kvalitetstab byttes for tættere promptmatch, når skalaen øges. |
| `guidance_scale_2` |  | number | no | `4` | 1 – 10 | Guidance-skala, der styrer, hvor tæt modellen følger prompten under dens andet trin. |
| `shift` |  | number | no | `5` | 1 – 10 | Indstilling for videoskift med et tilladt interval på 1.0–10.0. |
| `interpolator_model` |  | enum (string) | no | `film` | `none`, `film`, `rife` | Indstilling for frame-interpolation: vælg None for at springe interpolation over, eller angiv modellen, der skal udføre den. |
| `num_interpolated_frames` |  | integer | no | `1` | 0 – 4 | Indsæt 0–4 interpolerede frames i hvert mellemrum mellem to genererede frames. |
| `adjust_fps_for_interpolation` |  | boolean | no | `true` |  | Kontakt for justering af billedhastighed: false bevarer den angivne FPS, mens true skalerer den med én plus antallet af interpolerede frames. Derfor bliver 16 FPS til 32 FPS, når 1 frame interpoleres, og justering er aktiveret. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Indstilling for outputvideoens kvalitet, der bytter større filer for bedre visuel kvalitet, når værdien øges. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Vide skrivefunktion, hvor balanced er et kompromis mellem hastighed og kvalitet. Vælg small for de mindste filer og langsomste skrivning; hurtigere skrivning returnerer resultater tidligere, men opretter større filer. |

## 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" \

    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.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.
