{name} File Upload and URL Shortener
Welcome to the {name} file upload and URL shortening service.
This service allows you to easily upload files or shorten URLs for quick access.

Usage:
Upload a file:
curl -F file=@yourfile.ext {base_url}/
Shorten a URL:
curl -d "url=https://example.com" {base_url}/shorten
Details:
Files uploaded to this service are stored for {expiration_days} days or until they are automatically cleaned up.
The maximum file size is {max_file_size}MB.
URLs shortened with this service will redirect to the original URL for the same period.
Examples:
