# PixVerse V5 Transition API

> Clip de transition V5 entre une première et une dernière image, guidé par un prompt

Génère une vidéo reliant `first_image_url` à `end_image_url`, avec un `prompt` décrivant le déroulement du changement. Vous pouvez choisir le format, une résolution de 360p à 1080p et une durée de 5 ou 8 secondes. Les contrôles facultatifs sont `style`, `negative_prompt` et `seed`.

- Model id: `pixverse/v5/transition`
- Made by: PixVerse
- Category: Image to Video
- Output: video
- Price per run: from $0.15 / run (cheapest run $0.15 (150 API credits))
- Run: `POST https://api.doitong.com/v1/run/pixverse/v5/transition`

- Docs page: https://doitong.com/fr/developers/models/pixverse/v5/transition

## 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.com/v1/quote/pixverse/v5/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 |  |  | Instructions de transition soumises à une limite de longueur en octets : même un texte visuellement court peut dépasser cette limite, car les emoji, les lettres accentuées et les caractères non latins occupent plusieurs octets. Le maximum est de 2048 octets mesurés en UTF-8, et non un nombre de caractères. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Rapport d’aspect de la vidéo de sortie. |
| `resolution` |  | enum (string) | no | `720p` | `360p`, `540p`, `720p`, `1080p` | Résolution de la vidéo de sortie. |
| `duration` |  | enum (string) | no | `5` | `5`, `8` | Durée de la vidéo de sortie, mesurée en secondes. |
| `negative_prompt` |  | string | no | `` |  | Prompt de génération négatif soumis à une limite de longueur en octets : même un texte visuellement court peut dépasser cette limite, car les emoji, les lettres accentuées et les caractères non latins occupent plusieurs octets. Le maximum est de 2048 octets mesurés en UTF-8, et non un nombre de caractères. |
| `style` |  | enum (string) \| null | no |  | `anime`, `3d_animation`, `clay`, `comic`, `cyberpunk` | Style appliqué à la vidéo générée. |
| `seed` |  | integer \| null | no |  |  | Graine pour une génération vidéo reproductible. Une reproduction exacte à chaque exécution nécessite une version du modèle, un prompt et une graine inchangés. |
| `first_image_url` | `image` | string (image URL) | yes |  |  | URL d'image fournissant l'image initiale. |
| `end_image_url` | `end_image` | string (image URL) | yes |  |  | URL de l’image de la dernière image. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Le filtrage peut être assoupli en définissant false, si l'appelant est autorisé. |

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
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "end_image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "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 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/v5/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/v5/transition?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",
    "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"
  }),
});
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",
    "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/v5/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/v5/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.
