# Pika API

> Nội suy khung hình chính: nối từ 2 đến 5 hình ảnh bằng lời nhắc và thời lượng cho từng chuyển tiếp

Nhận từ 2 đến 5 hình ảnh khung hình chính trong `image_urls` và tạo video chuyển tiếp giữa chúng. Danh sách `transitions` tùy chọn phải có một mục cho mỗi khoảng trống (số hình ảnh trừ một), còn tổng thời gian chuyển tiếp không được vượt quá 25 giây. Nếu không cung cấp, mỗi chuyển tiếp kéo dài 5 giây và dùng `prompt` chung. Độ phân giải là 720p hoặc 1080p.

- Model id: `pika/v2.2/pikaframes`
- Made by: Pika
- Category: Image to Video
- Output: video
- Price per second of your output video: from $0.04 / second of output video (cheapest run $0.20 (200 API credits))
- Run: `POST https://api.doitong.com/v1/run/pika/v2.2/pikaframes`
- Quote: `POST https://api.doitong.com/v1/quote/pika/v2.2/pikaframes`
- Docs page: https://doitong.com/vi/developers/models/pika/v2.2/pikaframes

## Pricing

Price: **from $0.04 / second of output video** (the lowest tier; the quote prices your exact input). Price per second of your output video: 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:

- 720p: $0.04 / second of output video
- 1080p: $0.06 / second of output video

The full example input below costs $0.20 = 200 API credits (5 s output video × $0.04 (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/pika/v2.2/pikaframes` 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 |
|---|---|---|---|---|---|---|
| `image_urls` | `images` | array of image URL | yes |  |  | URL của 2–5 hình ảnh khung hình chính, với các chuyển cảnh được tạo giữa chúng. |
| `transitions` |  | array of object {duration, prompt} | no |  |  | Thiết lập cho từng chuyển cảnh, mặc định là chuyển cảnh 5 giây được định hướng bằng lời nhắc toàn cục khi bỏ qua. Tổng thời lượng không được vượt quá 25 giây và số mục phải bằng len(image_urls) - 1. |
| `transitions[].duration` |  | integer | no | `5` | 1 – 25 | Độ dài của chuyển cảnh này, tính theo giây. |
| `transitions[].prompt` |  | string \| null | no |  |  | Lời nhắc riêng cho chuyển cảnh này; khi được cung cấp, lời nhắc này thay thế lời nhắc toàn cục. |
| `prompt` |  | string \| null | no |  |  | Lời nhắc mặc định dùng chung cho các chuyển cảnh, bị thay thế bởi lời nhắc riêng của từng chuyển cảnh. |
| `negative_prompt` |  | string | no | `` |  | Lời nhắc phủ định dùng để điều hướng mô hình. |
| `seed` |  | integer \| null | no |  |  | Giá trị seed được bộ tạo số ngẫu nhiên sử dụng. |
| `resolution` |  | enum (string) | no | `720p` | `720p`, `1080p` | Độ phân giải của video đầu ra. |

File parameters (`images`) 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
{
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  ]
}
```

A fuller example:

```json
{
  "image_urls": [
    "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/pika/v2.2/pikaframes?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_urls": [
      "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/pika/v2.2/pikaframes?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "image_urls": [
      "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 = {
    "image_urls": [
        "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/pika/v2.2/pikaframes", 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": "pika/v2.2/pikaframes",
      "input": {
        "image_urls": [
          "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.
