APIFront fundamentally reimagines traditional API architecture by eliminating complex infrastructure layers. Our Function as an API paradigm allows enterprises to focus solely on which business functions to expose, maintaining complete control over security, authentication, and monitoring.
For AI vendors, we provide a standardized access framework that simplifies integration with customer systems—creating a secure, seamless connection between enterprise functions and modern AI applications without infrastructure complexity.
Implementation Details
🟢 Transform any NodeJS function(s)
// All functions for "user-service" are proxied from this script
proxy.proxy('user-service/create-user', createUser);
proxy.proxy('user-service/update-profile', updateProfile);
// Start the proxy - this instance can now be load balanced by running multiple copies
proxy.start().then(() => {
console.log('User service functions are now exposed as APIs');
}).catch(err => console.error(err));
🔵 Transform any Python function(s)
# All functions for "analytics" are proxied from this script
proxy.proxy("analytics/generate-report", generate_report)
proxy.proxy("analytics/visualize-data", visualize_data)
# Start the proxy - this instance can now be load balanced by running multiple copies
proxy.start()
