# PixVerse C1 Text To Video API

> C1 ya maandishi-hadi-video yenye klipu za 1 hadi sekunde 15, uwiano wa pande nane, hadi 1080p na sauti ya hiari

Huzalisha video kutoka `prompt` ya maandishi. `duration` inaweza kuwa nambari yoyote kamili kutoka 1 hadi sekunde 15, na uwiano wa pande unaweza kuwa 16:9, 4:3, 1:1, 3:4, 9:16, 2:3, 3:2 au 21:9. Ubora ni kutoka 360p hadi 1080p. Kuwasha `generate_audio_switch` huongeza muziki, madoido na mazungumzo.

- Model id: `pixverse/c1/text-to-video`

- Category: Text to Video
- Output: video
- Price: from $0.03 / second (5 s ≈ $0.15) (cheapest run $0.15 (150 API credits))
- Run: `POST https://api.doitong.ru/v1/run/pixverse/c1/text-to-video`

## Pricing

Price: **from $0.03 / second (5 s ≈ $0.15)** (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 `generate_audio_switch` = true and `resolution` = 360p: $0.04 (40 API credits) / second
- When `resolution` = 360p: $0.03 (30 API credits) / second
- When `generate_audio_switch` = true and `resolution` = 540p: $0.05 (50 API credits) / second
- When `resolution` = 540p: $0.04 (40 API credits) / second
- When `generate_audio_switch` = true and `resolution` = 720p: $0.065 (65 API credits) / second
- When `resolution` = 720p: $0.05 (50 API credits) / second
- When `generate_audio_switch` = true and `resolution` = 1080p: $0.12 (120 API credits) / second
- When `resolution` = 1080p: $0.095 (95 API credits) / second

The full example input below costs $0.25 = 250 API credits (5 s × 50 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.ru/v1/quote/pixverse/c1/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 |  |  | Kidokezo cha uzalishaji wa video chenye kikomo cha ukubwa kinachopimwa kwa baiti: hata maandishi mafupi kwa kuonekana yanaweza kukizidi emoji, herufi zenye alama za matamshi au herufi zisizo za Kilatini zinapotumia baiti nyingi kwa kila herufi. Urefu wa juu uliosimbwa ni baiti 2048 kwa kutumia UTF-8; idadi ya herufi haiamui kama kinafaa. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `4:3`, `1:1`, `3:4`, `9:16`, `2:3`, `3:2`, `21:9` | Uwiano wa picha wa video ya tokeo. |
| `resolution` |  | enum (string) | no | `720p` | `360p`, `540p`, `720p`, `1080p` | Mwonekano wa video ya tokeo. |
| `duration` |  | integer | no | `5` | 1 – 15 | Urefu wa video iliyozalishwa, kutoka sekunde 1 hadi 15. |
| `seed` |  | integer \| null | no |  |  | Mbegu ya uzalishaji wa video unaoweza kurudiwa. Kurudia kwa usahihi kila uendeshaji kunahitaji toleo la modeli, kidokezo na mbegu visibadilike. |
| `generate_audio_switch` | `generate_audio` | boolean | no | `false` |  | Kigeuza uzalishaji wa sauti kwa muziki wa mandharinyuma, madoido ya sauti na mazungumzo. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Ukaguzi unaweza kulegezwa kwa kuweka false, ikiwa mpigaji simu ameidhinishwa. |

## 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.ru/v1/run/pixverse/c1/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/c1/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/c1/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/c1/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.
