## Pricing

Price: **from $0.15 / run** (the lowest tier; the quote prices your exact input). Price per run: 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:

- 360p: $0.15 / run
- 540p: $0.15 / run
- 720p: $0.20 / run
- 360p, 8_s: $0.30 / run
- 540p, 8_s: $0.30 / run
- 720p, 8_s: $0.40 / run
- 1080p: $0.40 / run
- 1080p, 8_s: $0.80 / run

The full example input below costs $0.20 = 200 API credits (1 run × $0.20 (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/pixverse/v3.5/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 |  |  | Anogiad cynhyrchu fideo â therfyn maint seiliedig ar feitiau: gall testun sy'n fyr yn weledol ragori arno pan fydd emoji, llythrennau ag acenion, neu nodau nad ydynt yn Lladin yn defnyddio sawl beit fesul nod. Yr uchafswm hyd wedi'i amgodio yw 2048 beit gan ddefnyddio UTF-8; nid yw cyfrif nodau'n pennu a yw'n ffitio. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Cymhareb agwedd ar gyfer y fideo allbwn. |

| `duration` |  | enum (string) | no | `5` | `5`, `8` | Hyd fideo, yn amodol ar uchafswm o 5 eiliad ar gyfer allbwn 1080p; nodwch yr hyd mewn eiliadau. |
| `negative_prompt` |  | string | no | `` |  | Anogiad cynhyrchu negyddol â therfyn hyd seiliedig ar feitiau: gall testun sy'n fyr yn weledol ragori ar y terfyn oherwydd bod emoji, llythrennau ag acenion a nodau nad ydynt yn Lladin yn defnyddio sawl beit. Yr uchafswm yw 2048 beit wedi'i fesur yn UTF-8, nid cyfrif nodau. |
| `style` |  | enum (string) \| null | no |  | `anime`, `3d_animation`, `clay`, `comic`, `cyberpunk` | Arddull a gymhwysir i'r fideo a gynhyrchir. |
| `seed` |  | integer \| null | no |  |  | Hadau ar gyfer cynhyrchu fideo ailadroddadwy. Er mwyn atgynhyrchu'n union ar bob rhediad, rhaid cadw fersiwn y model, yr anogiad a'r hedyn heb eu newid. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Gellir llacio'r sgrinio drwy osod false, ar yr amod bod y galwr wedi'i awdurdodi. |

}
```

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.ru/v1/run/pixverse/v3.5/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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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/pixverse/v3.5/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.ru/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/pixverse/v3.5/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.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": "pixverse/v3.5/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.
