How to Use

Start the Unified API Server

python api_server_unified.py

Server runs on http://localhost:8000

API Endpoints

Create Video

POST /api/videos
{
    "input_type": "text|pdf|url",
    "input_data": "...",
    "quality": "low|medium|high|ultra",
    "category": "tech_system|product_startup|mathematical"
}

Check Job Status

GET /api/jobs/{job_id}

Download Video

GET /api/videos/{job_id}

Example Requests

Text Input:

{
    "input_type": "text",
    "input_data": "Explain how a distributed system handles requests",
    "category": "tech_system",
    "quality": "high"
}

URL Input:

{
    "input_type": "url",
    "input_data": "https://example.com/blog/post",
    "category": "product_startup",
    "quality": "medium"
}

PDF Input:

{
    "input_type": "pdf",
    "input_data": "base64_encoded_pdf_string",
    "category": "mathematical",
    "quality": "high"
}

Features

Visual Themes

Each category has distinct visual styling:

• Tech: Dark professional backgrounds, architecture diagrams
• Product: Light modern backgrounds, UI elements, gradients
• Research: Dark educational backgrounds, mathematical equations

Error Handling

• Automatic code validation before rendering
• Auto-fix for common issues (missing imports, undefined colors, etc.)
• Retry with fallback models if generation fails
• Detailed error messages

Input Processing

• Text: Direct prompt processing
• PDF: Base64 decoding and content extraction
• URL: Web scraping with content extraction

Next Steps

1. Install new dependencies:

   poetry install
   

2. Test the unified server:

   python api_server_unified.py
   

3. Try different input types and categories

4. Monitor job status and video generation

Notes

• The unified server replaces the need for separate 2D/3D servers
• All categories use the same code generation pipeline with different themes
• Web scraping respects robots.txt and handles authentication errors gracefully
• Code validation prevents most rendering failures
