# PixVerse V6 Transition API

> Video ya fremu ya kwanza hadi fremu ya mwisho kati ya picha mbili, sekunde 1 hadi 15, yenye uwiano nane wa picha

Huchukua `prompt`, `first_image_url` na `end_image_url`, kisha huzalisha mpito kati yake. Muda ni sekunde 1 hadi 15, mwonekano ni 360p hadi 1080p, na `aspect_ratio` inajumuisha 16:9, 4:3, 1:1, 3:4, 9:16, 2:3, 3:2 na 21:9. Uzalishaji wa klipu nyingi, mipangilio ya mitindo, `seed` na uzalishaji wa sauti vinaweza kuwezeshwa.

- 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 |  |  | Maelekezo ya mpito yenye kikomo cha urefu kinachopimwa kwa baiti: hata maandishi mafupi kwa kuonekana yanaweza kukizidi kwa sababu emoji, herufi zenye alama za matamshi na herufi zisizo za Kilatini hutumia baiti nyingi. Kikomo cha juu ni baiti 2048, kinachopimwa kwa UTF-8, si idadi ya herufi. |
| `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 ya kuzalisha, unaopimwa kwa sekunde; kwa v6, kiwango kinachotumika ni sekunde 1–15. |
| `negative_prompt` |  | string | no | `` |  | Kidokezo hasi cha uzalishaji chenye kikomo cha urefu kinachopimwa kwa baiti: hata maandishi mafupi kwa kuonekana yanaweza kukizidi kwa sababu emoji, herufi zenye alama za matamshi na herufi zisizo za Kilatini hutumia baiti nyingi. Kikomo cha juu ni baiti 2048, kinachopimwa kwa UTF-8, si idadi ya herufi. |
| `style` |  | enum (string) \| null | no |  | `anime`, `3d_animation`, `clay`, `comic`, `cyberpunk` | Mtindo unaotumika kwenye video iliyozalishwa. |
| `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. |
| `generate_multi_clip_switch` |  | boolean | no | `false` |  | Kigeuza uzalishaji wa klipu nyingi kinachowezesha mabadiliko yanayobadilika ya kamera. |
| `thinking_type` |  | enum (string) \| null | no |  | `enabled`, `disabled`, `auto` | Mpangilio wa uboreshaji wa kidokezo: 'enabled' hutumia uboreshaji, 'disabled' huuzima, na 'auto' huiachia modeli iamue. |
| `first_image_url` | `image` | string (image URL) | yes |  |  | URL ya picha inayotoa fremu ya mwanzo. |
| `end_image_url` | `end_image` | string (image URL) | yes |  |  | URL ya picha ya fremu ya mwisho. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Ukaguzi unaweza kulegezwa kwa kuweka false, ikiwa mpigaji simu ameidhinishwa. |

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`.

## 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",

    "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

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/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

```

### 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.
