# Wan v2.6 Text to Video API

> Wan 2.6 text-to-video met clips van 5, 10 of 15 seconden, vijf beeldverhoudingen en optionele achtergrondaudio

Maakt video vanuit een prompt van maximaal 1500 tekens in het Chinees of Engels, met ondersteuning voor getimede multi-shotbeschrijvingen. `aspect_ratio` biedt 16:9, 9:16, 1:1, 4:3 en 3:4; `resolution` is 720p of 1080p en `duration` is 5, 10 of 15 seconden. Een optionele `audio_url` voegt achtergrondmuziek toe. Promptuitbreiding en `multi_shots` staan standaard aan.

- Model id: `wan/v2.6/text-to-video`
- Made by: Alibaba
- Category: Text to Video
- Output: video
- Price: from $0.10 / second (5 s ≈ $0.50) (cheapest run $0.50 (500 API credits))
- Run: `POST https://api.doitong.com/v1/run/wan/v2.6/text-to-video`
- Quote: `POST https://api.doitong.com/v1/quote/wan/v2.6/text-to-video`
- Docs page: https://doitong.com/nl/developers/models/wan/v2.6/text-to-video

## Pricing

Price: **from $0.10 / second (5 s ≈ $0.50)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 15).

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `resolution` = 1080p: $0.15 (150 API credits) / second

The full example input below costs $0.75 = 750 API credits (5 s × 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/v2.6/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

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  | ≥ 1 characters | Beschrijf de te genereren video in maximaal 1500 tekens in het Chinees of Engels. Structureer meerdere shots als volgt: 'Overall description. First shot [0-3s] content. Second shot [3-5s] content.' |
| `audio_url` | `audio` | string (audio URL) \| null | no |  |  | URL van een openbaar toegankelijk WAV- of MP3-bestand voor achtergrondmuziek, met een duur van 3–30 s en maximaal 15 MB. De geselecteerde videoduur (5, 10 of 15 seconden) beperkt het afspelen tot de eerste N seconden; overtollige audio wordt verwijderd. Als de audio eerder eindigt, is de resterende video stil. Bij 3 seconden audio en een video van 5 seconden speelt bijvoorbeeld gedurende de eerste 3 seconden geluid, gevolgd door 2 seconden stilte. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `9:16`, `1:1`, `4:3`, `3:4` | Instelling voor de breedte-hoogteverhouding van de video, met een ruimere selectie verhoudingen in Wan 2.6. |
| `resolution` |  | enum (string) | no | `1080p` | `720p`, `1080p` | Kies het resolutieniveau van de video. Voor Wan 2.6 T2V zijn 720p en 1080p beschikbaar; 480p wordt niet ondersteund. |
| `duration` |  | enum (string) | no | `5` | `5`, `10`, `15` | Videolengte uit de beschikbare duurwaarden: 5, 10 of 15 seconden. |
| `negative_prompt` |  | string \| null | no | `` |  | Negatieve prompt die ongewenste inhoud specificeert, beperkt tot 500 tekens. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | LLM-gebaseerde promptherschrijving, die extra verwerkingstijd inruilt voor betere resultaten met korte prompts. |
| `multi_shots` |  | boolean | no | `true` |  | Intelligente segmentatie in meerdere shots maakt bij true coherente videonarratieven; false produceert één shot. Dit werkt alleen wanneer enable_prompt_expansion True is. |
| `seed` |  | integer \| null | no |  |  | Seed die generatie reproduceerbaar maakt. Als je deze instelt op None, wordt willekeurig een seed gekozen. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Schakelaar voor veiligheidscontrole waarvan de uitgeschakelde instelling accountautorisatie vereist. Zonder die autorisatie wordt elke request gecontroleerd, ongeacht de instelling; true schakelt de controle in. |

File parameters (`audio`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

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

A fuller example:

```json
{
  "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/v2.6/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/v2.6/text-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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/v2.6/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/v2.6/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.
