# Wan v2.2 5B · Text to Video API

> Text-to-video with the 5B model: 580p or 720p, 16:9, 9:16 or 1:1, optional frame interpolation

Creates a video clip from a text `prompt`. Length is set by `num_frames` (17 to 161) and `frames_per_second` (4 to 60), with `resolution` of 580p or 720p and aspect ratios 16:9, 9:16 or 1:1. Frame interpolation with film or rife can be enabled, and output quality and file write mode are adjustable. This is the standard-guidance variant with up to 50 inference steps.

- Model id: `wan/v2.2-5b/text-to-video`
- Made by: Alibaba
- Category: Text to Video
- Output: video
- Price: $0.15 / video (cheapest run $0.15 (150 API credits))
- Run: `POST https://api.doitong.com/v1/run/wan/v2.2-5b/text-to-video`
- Quote: `POST https://api.doitong.com/v1/quote/wan/v2.2-5b/text-to-video`

## Pricing

Price: **$0.15 / video**. Billed once per generated video.

The full example input below costs $0.15 = 150 API credits (1 video × 150 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/wan/v2.2-5b/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 |  |  | Text instructions that guide video generation. |
| `negative_prompt` |  | string | no | `` |  | Negative prompt applied when generating a video. |
| `num_frames` |  | integer | no | `81` | 17 – 161 | Frame count for generation, with an inclusive range of 17–161. |
| `frames_per_second` |  | integer \| null | no | `24` | 4 – 60 | Generated video frame rate, accepting values from 4 to 60; setting `adjust_fps_for_interpolation` to false preserves this rate unchanged. With interpolation in use and `adjust_fps_for_interpolation` true (its default), multiply this rate by one plus the interpolated frame count to obtain the final FPS. For example, 16 FPS with 1 interpolated frame becomes 32 FPS. |
| `seed` |  | integer \| null | no |  |  | Seed that makes generation reproducible. Setting it to None selects a seed randomly. |
| `resolution` |  | enum (string) | no | `720p` | `580p`, `720p` | Output video resolution, either 580p or 720p. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `9:16`, `1:1` | Output video's aspect ratio, either 16:9 or 9:16. |
| `num_inference_steps` |  | integer | no | `40` | 2 – 50 | Sampling step count, trading longer processing time for better quality as the count increases. |
| `enable_safety_checker` |  | boolean | no | `false` |  | Input safety screening before processing, which only authorized accounts may turn off. Requests lacking authorization are always screened; otherwise, true enables screening. |
| `enable_output_safety_checker` |  | boolean | no | `false` |  | Controls safety screening of the generated video; setting true enables a check after generation. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Allow a large language model to enrich the prompt with details. Enabling this expansion leaves the prompt's meaning unchanged. |
| `guidance_scale` |  | number | no | `3.5` | 1 – 10 | Classifier-free guidance strength, trading possible quality loss for closer prompt matching as the scale increases. |
| `shift` |  | number | no | `5` | 1 – 10 | Video shift setting, with an allowed range of 1.0–10.0. |
| `interpolator_model` |  | enum (string) | no | `film` | `none`, `film`, `rife` | Frame interpolation setting: choose None to skip interpolation, or specify the model to perform it. |
| `num_interpolated_frames` |  | integer | no | `0` | 0 – 4 | Insert 0–4 interpolated frames into every gap between two generated frames. |
| `adjust_fps_for_interpolation` |  | boolean | no | `true` |  | Frame-rate adjustment toggle: false preserves the supplied FPS, whereas true scales it by one plus the interpolated frame count. Thus, 16 FPS becomes 32 FPS when 1 frame is interpolated and adjustment is enabled. |
| `video_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Output video quality setting that trades larger files for improved visuals as the setting increases. |
| `video_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Video writing mode, with balanced offering a compromise between speed and quality. Choose small for the smallest files and slowest writing; faster writing returns results sooner but creates larger files. |

## Example input

Required parameters only:

  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

```

## 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.com/v1/run/wan/v2.2-5b/text-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/wan/v2.2-5b/text-to-video?wait=20", {

let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/wan/v2.2-5b/text-to-video", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    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.com/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/v2.2-5b/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.
