Introduction

The download video endpoint is used to retrieve completed video file data.

This endpoint is only supported by Sora 2 model. Other models (Veo, Doubao Seedance) return the video URL directly in the query task response, no additional download step required.

Authentication

Bearer Token, e.g., Bearer sk-xxxxxxxxxx

Query Parameters

string

required

Video ID, the task_id returned by the query task endpoint

cURL Example

curl -X GET "https://api.mixroute.ai/v1/video/generations/download?id=video_69095b4ce0048190893a01510c0c98b0" \
  -H "Authorization: Bearer sk-xxxxxxxxxx"

Response Example

{
  "success": true,
  "generation_id": "video_69095b4ce0048190893a01510c0c98b0",
  "task_id": "video_69095b4ce0048190893a01510c0c98b0",
  "format": "mp4",
  "size": 15728640,
  "base64": "AAAAIGZ0eXBpc29tAAACAGlzb21pc28yYXZjMW1wNDEAAAAIZnJlZQAAB...",
  "data_url": "data:video/mp4;base64,AAAAIGZ0eXBpc29tAAACAGlzb21pc28yYXZjMW1wNDEAAAAIZnJlZQAAB..."
}

Response Fields

Field	Type	Description
`success`	boolean	Whether the request was successful
`generation_id`	string	Generation ID (same as videoId)
`task_id`	string	Task ID
`format`	string	Video format (fixed to `"mp4"`)
`size`	number	Video file size (bytes)
`base64`	string	Base64 encoded video data
`data_url`	string	Data URL format video data, can be used directly in frontend `<video>` tag

Usage Guide

Using data_url in Frontend

The data_url field can be used directly in HTML <video> tag:

<video src="data:video/mp4;base64,AAAAIGZ0eXBpc29tAAACAGlzb21pc28yYXZjMW1wNDEAAAAIZnJlZQAAB..." controls></video>

Download and Save File

JavaScript Example

// Get base64 data from response
const response = await fetch('https://api.mixroute.ai/v1/video/generations/download?id=video_xxx', {
  headers: {
    'Authorization': 'Bearer sk-xxxxxxxxxx'
  }
});
const data = await response.json();

// Convert base64 to Blob
const binaryString = atob(data.base64);
const bytes = new Uint8Array(binaryString.length);
for (let i = 0; i < binaryString.length; i++) {
  bytes[i] = binaryString.charCodeAt(i);
}
const blob = new Blob([bytes], { type: 'video/mp4' });

// Create download link
const url = URL.createObjectURL(blob);
const a = document.createElement('a');
a.href = url;
a.download = 'video.mp4';
a.click();
URL.revokeObjectURL(url);

Python Example

import requests
import base64

def download_video(video_id, api_key):
    """Download video and save as file"""
    url = f"https://api.mixroute.ai/v1/video/generations/download?id={video_id}"
    headers = {"Authorization": f"Bearer {api_key}"}

    response = requests.get(url, headers=headers)
    data = response.json()

    if data.get("success"):
        # Decode base64 data
        video_data = base64.b64decode(data["base64"])

        # Save to file
        with open("video.mp4", "wb") as f:
            f.write(video_data)

        print(f"✅ Video saved: video.mp4 (size: {data['size']} bytes)")
        return True
    else:
        print("❌ Download failed")
        return False

Complete Workflow Example (Sora 2)

1. Submit Video Generation Task

curl -X POST "https://api.mixroute.ai/v1/video/generations" \
  -H "Authorization: Bearer sk-xxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "sora-2",
    "prompt": "A cute kitten playing in the garden",
    "seconds": "4",
    "size": "720x1280"
  }'

Response:

{
  "task_id": "video_69095b4ce0048190893a01510c0c98b0",
  "status": "submitted",
  "format": "mp4"
}

2. Query Task Status (Poll Until Success)

curl -X GET "https://api.mixroute.ai/v1/video/generations/video_69095b4ce0048190893a01510c0c98b0" \
  -H "Authorization: Bearer sk-xxxxxxxxxx"

When the status is succeeded, proceed to the next step.

3. Download Video File

curl -X GET "https://api.mixroute.ai/v1/video/generations/download?id=video_69095b4ce0048190893a01510c0c98b0" \
  -H "Authorization: Bearer sk-xxxxxxxxxx"

Notes

The download endpoint returns Base64 encoded video data, suitable for direct display in frontend or saving
For large files, consider using streaming download or direct URL download
Video format is fixed to MP4

curl --request GET \
  --url 'https://api.mixroute.ai/v1/video/generations/download?id=video_xxx' \
  --header 'Authorization: Bearer sk-xxxxxxxxxx'

import requests
