# PixVerse V6 Transition API

> Video od prvního k poslednímu snímku mezi dvěma obrázky dlouhé 1 až 15 sekund s osmi poměry stran

Přijímá `prompt`, `first_image_url` a `end_image_url` a generuje přechod mezi nimi. Délka je 1 až 15 sekund, rozlišení 360p až 1080p a `aspect_ratio` zahrnuje 16:9, 4:3, 1:1, 3:4, 9:16, 2:3, 3:2 a 21:9. Lze povolit generování více klipů, předvolby stylu, `seed` a generování zvuku.

- Model id: `pixverse/v6/transition`

- Category: Image to Video
- Output: video
- Price: from $0.025 / second (5 s ≈ $0.125) (cheapest run $0.125 (125 API credits))
- Run: `POST https://api.doitong.com/v1/run/pixverse/v6/transition`

## Pricing

Price: **from $0.025 / second (5 s ≈ $0.125)** (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: $0.035 (35 API credits) / second
- When `resolution` = 360p: $0.025 (25 API credits) / second
- When `generate_audio_switch` = true and `resolution` = 540p: $0.045 (45 API credits) / second
- When `resolution` = 540p: $0.035 (35 API credits) / second
- When `generate_audio_switch` = true and `resolution` = 720p: $0.06 (60 API credits) / second
- When `resolution` = 720p: $0.045 (45 API credits) / second
- When `generate_audio_switch` = true and `resolution` = 1080p: $0.115 (115 API credits) / second
- When `resolution` = 1080p: $0.09 (90 API credits) / second

The full example input below costs $0.225 = 225 API credits (5 s × 45 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/pixverse/v6/transition` 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 |  |  | Pokyny pro přechod s limitem délky založeným na bajtech: i vizuálně krátký text může limit překročit, protože emoji, písmena s diakritikou a nelatinkové znaky zabírají několik bajtů. Maximum je 2048 bajtů měřených v UTF-8, nikoli počet znaků. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `4:3`, `1:1`, `3:4`, `9:16`, `2:3`, `3:2`, `21:9` | Poměr stran výstupního videa. |
| `resolution` |  | enum (string) | no | `720p` | `360p`, `540p`, `720p`, `1080p` | Rozlišení výstupního videa. |
| `duration` |  | integer | no | `5` | 1 – 15 | Délka videa k vygenerování měřená v sekundách; pro v6 je podporovaný rozsah 1–15 sekund. |
| `negative_prompt` |  | string | no | `` |  | Negativní prompt generování s limitem délky založeným na bajtech: i vizuálně krátký text může limit překročit, protože emoji, písmena s diakritikou a nelatinkové znaky zabírají několik bajtů. Maximum je 2048 bajtů měřených v UTF-8, nikoli počet znaků. |
| `style` |  | enum (string) \| null | no |  | `anime`, `3d_animation`, `clay`, `comic`, `cyberpunk` | Styl použitý pro generované video. |
| `seed` |  | integer \| null | no |  |  | Seed pro opakovatelné generování videa. Přesná reprodukce při každém spuštění vyžaduje nezměněnou verzi modelu, prompt a seed. |
| `generate_audio_switch` | `generate_audio` | boolean | no | `false` |  | Přepínač generování zvuku pro hudbu na pozadí, zvukové efekty a dialogy. |
| `generate_multi_clip_switch` |  | boolean | no | `false` |  | Přepínač generování více klipů, který umožňuje dynamické změny kamery. |
| `thinking_type` |  | enum (string) \| null | no |  | `enabled`, `disabled`, `auto` | Nastavení optimalizace promptu: 'enabled' použije optimalizaci, 'disabled' ji vypne a 'auto' nechá rozhodnutí na modelu. |
| `first_image_url` | `image` | string (image URL) | yes |  |  | URL obrázku poskytujícího úvodní snímek. |
| `end_image_url` | `end_image` | string (image URL) | yes |  |  | URL obrázku pro poslední snímek. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Kontrolu lze uvolnit nastavením na false, pokud je volající autorizován. |

File parameters (`image`, `end_image`) 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

```

## 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/pixverse/v6/transition?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",
    "first_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "end_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }'

# 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/pixverse/v6/transition?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({

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

  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",
    "first_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "end_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/pixverse/v6/transition", 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": "pixverse/v6/transition",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "first_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "end_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      },
      "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.
