# Wan-2.2 Text-to-Video A14B API

> A14B text-to-video su 480p–720p išvestimi, dviem valdymo etapais ir pasirenkama interpolacija

Generuoja vaizdo įrašą iš tekstinio `prompt`. `num_frames` yra nuo 17 iki 161, `frames_per_second` – nuo 4 iki 60, o `resolution` gali būti 480p, 580p arba 720p, naudojant 16:9, 9:16 arba 1:1. Galimos dvi valdymo reikšmės, `acceleration` nustatymas ir film arba rife interpolacija (pagal numatytuosius nustatymus vienas interpoliuotas kadras).

- 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/lt/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 |  |  | Tekstinės instrukcijos, valdančios vaizdo įrašo generavimą. |
| `negative_prompt` |  | string | no | `` |  | Generuojant vaizdo įrašą taikomas neigiamas raginys. |
| `num_frames` |  | integer | no | `81` | 17 – 161 | Generavimo kadrų skaičius nuo 17 iki 161 imtinai. |
| `frames_per_second` |  | integer \| null | no | `16` | 4 – 60 | Sugeneruoto vaizdo įrašo kadrų dažnis nuo 4 iki 60; nustačius `adjust_fps_for_interpolation` į false, šis dažnis išlaikomas nepakitęs. Naudojant interpoliaciją ir `adjust_fps_for_interpolation` esant true (numatytoji reikšmė), šį dažnį padauginus iš vieneto ir interpoliuotų kadrų skaičiaus sumos gaunamas galutinis FPS. Pavyzdžiui, 16 FPS ir 1 interpoliuotas kadras tampa 32 FPS. |
| `seed` |  | integer \| null | no |  |  | Generavimą atkurianti pradinė reikšmė. Nustačius None, ji parenkama atsitiktinai. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `580p`, `720p` | Išvesties vaizdo įrašo raiška: 480p, 580p arba 720p. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `9:16`, `1:1` | Išvesties vaizdo įrašo kraštinių santykis: 16:9 arba 9:16. |
| `num_inference_steps` |  | integer | no | `27` | 2 – 40 | Diskretizavimo žingsnių skaičius: didėjant skaičiui, ilgesnis apdorojimas suteikia geresnę kokybę. |
| `enable_safety_checker` |  | boolean | no | `false` |  | Įvesties saugos tikrinimas prieš apdorojimą, kurį išjungti gali tik įgaliotos paskyros. Neįgaliotos užklausos visada tikrinamos; kitu atveju true įjungia tikrinimą. |
| `enable_output_safety_checker` |  | boolean | no | `false` |  | Valdo sugeneruoto vaizdo įrašo saugos tikrinimą; true įjungia patikrą po generavimo. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Leidžia dideliam kalbos modeliui papildyti raginį detalėmis. Įjungus šį išplėtimą raginio reikšmė nesikeičia. |
| `acceleration` |  | enum (string) | no | `regular` | `none`, `regular` | Spartinimo nustatymas; rekomenduojama reikšmė yra 'regular'. Didesnis spartinimas mažina kokybę, kad sutrumpintų generavimo laiką. |
| `guidance_scale` |  | number | no | `3.5` | 1 – 10 | Klasifikatoriaus nenaudojančio valdymo stiprumas; didėjant masteliui galima kokybės praradimo rizika keičiama į glaudesnį atitikimą ragin iui. |
| `guidance_scale_2` |  | number | no | `4` | 1 – 10 | Kreipimo mastelis, nurodantis, kaip tiksliai modelis laikosi raginio antrajame etape. |
| `shift` |  | number | no | `5` | 1 – 10 | Vaizdo įrašo poslinkio nustatymas, leidžiamas intervalas 1.0–10.0. |
| `interpolator_model` |  | enum (string) | no | `film` | `none`, `film`, `rife` | Kadrų interpoliacijos nustatymas: pasirinkite None, kad interpoliacija nebūtų atliekama, arba nurodykite ją atliekantį modelį. |
| `num_interpolated_frames` |  | integer | no | `1` | 0 – 4 | Į kiekvieną tarpą tarp dviejų sugeneruotų kadrų įterpkite nuo 0 iki 4 interpoliuotų kadrų. |
| `adjust_fps_for_interpolation` |  | boolean | no | `true` |  | Kadrų dažnio koregavimo jungiklis: false išlaiko pateiktą FPS, o true padaugina jį iš vieneto ir interpoliuotų kadrų skaičiaus sumos. Taigi, interpoliavus 1 kadrą, 16 FPS tampa 32 FPS, jei koregavimas įjungtas. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Išvesties vaizdo įrašo kokybės nustatymas: didesnė reikšmė sukuria didesnius failus, bet pagerina vaizdą. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Vaizdo įrašo rašymo režimas: balanced suderina spartą ir kokybę. Pasirinkite small mažiausiems failams ir lėčiausiam rašymui; spartesnis rašymas rezultatus pateikia anksčiau, bet sukuria didesnius failus. |

## 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.
