# Depth Anything Video API

> 估算輸入影片每個影格的深度圖，支援尺寸、色彩映射與並排比較選項

將影片轉換為深度視覺化結果，確保各影格之間的結果一致。可選擇模型尺寸（VDA-Small、VDA-Base 或 VDA-Large）、色彩映射（grayscale、turbo、inferno、magma 或 viridis）及最高 1080p 的輸出 `resolution`。也可使用 `side_by_side` 將原始影片與深度影片並排呈現，使用 `max_frames` 限制影格數（最多 2400），或將原始深度值匯出為 .npz 檔案。

- Model id: `depth-anything-video`
- Made by: ByteDance
- Category: Video to Video
- Output: video
- Price per second of your input video: $0.04 / second of input video (cheapest run $0.04 (40 API credits))
- Run: `POST https://api.doitong.com/v1/run/depth-anything-video`
- Quote: `POST https://api.doitong.com/v1/quote/depth-anything-video`
- Docs page: https://doitong.com/zh-TW/developers/models/depth-anything-video

## Pricing

Price: **$0.04 / second of input video**. Price per second of your input 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.

The full example input below costs $0.40 = 400 API credits (10 s input video × $0.04).

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/depth-anything-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 |
|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | 指向用於深度估計影片的 URL。 |
| `model` |  | enum (string) | no | `VDA-Large` | `VDA-Small`, `VDA-Base`, `VDA-Large` | 深度估計模型的大小；VDA-Large 提供最高品質，VDA-Small 的執行速度最快。 |
| `colormap` |  | enum (string) | no | `grayscale` | `grayscale`, `turbo`, `inferno`, `magma`, `viridis` | 深度視覺化調色盤：'grayscale' 顯示原始正規化深度，'viridis' 提供色盲友善的檢視方式，'inferno' 或 'magma' 提供感知一致性。建議使用的 'turbo' 調色盤會將鄰近區域對應為暖色，遠處區域對應為冷色。 |
| `resolution` |  | enum (string) | no | `auto` | `auto`, `360p`, `480p`, `720p`, `1080p` | 輸出的解析度；`auto` 會保留輸入解析度，最高達 1080p。可用值：'auto'、'360p'、'480p'、'720p'、'1080p'。 |
| `max_frames` |  | integer \| null | no |  | > 0 | 影格處理上限，最高為 2400。設為 None 同樣允許最多 2400 個影格。 |
| `output_fps` |  | number \| null | no |  | > 0 | 輸出影片的影格率。None 會保留輸入影格率。 |
| `side_by_side` |  | boolean | no | `false` |  | 控制是否輸出並排比較原始視圖與深度視圖的影片。 |
| `include_raw_depths` |  | boolean | no | `false` |  | 控制是否將原始 float32 深度資料匯出至 .npz 檔案，其中包含 `depths` [N,H,W]、`min_depth`、`max_depth`、`fps`、`model` 和 `shape`。 |

File parameters (`video`) 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
{
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

A fuller example:

```json
{
  "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

## 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/depth-anything-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }'

# 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/depth-anything-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }),
});
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 = {
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/depth-anything-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.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": "depth-anything-video",
      "input": {
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
      },
      "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.
