💻 MicroSaaS APIs

Pre-built functionality, ready to plug in. When building a MicroSaaS, we save thousands and weeks of engineering time by using these API endpoints designed around common features.

The Financial Impact

$20K+

Development Savings

Compared to building these APIs from scratch

8+ weeks

Time Saved

Get to market faster and start generating revenue

70%

Lower Maintenance

Reduce ongoing engineering costs with our managed APIs

Profit-First Architecture

Our APIs are designed with a profit-first mindset. By using serverless architecture and pay-as-you-go pricing, the operational costs of the MicroSaaS will scale linearly with revenue — maintaining high profit margins even as you grow.

Secure by Default

All endpoints use HTTPS, rate limiting, and proper authentication mechanisms to keep your data safe.

Rapid Integration

Simple, consistent API design with comprehensive documentation makes integration quick and painless.

Scalable

Built on serverless architecture that automatically scales with your user base and traffic patterns.

Production Ready

Thoroughly tested in real-world applications with monitoring, logging, and error handling built in.

Simple Integration

Our APIs are designed to be easy to integrate with any frontend. Here's an example of how to use our authentication API to register a new user and log them in.

Consistent response format: All APIs follow the same response structure for predictable integration

Detailed error messages: Clear error codes and messages to help debug issues

SDK available: Our JavaScript/TypeScript SDKs allow for even easier integration

auth-example.js

import { MicroSaaSAPI } from '@microsaasfactory/api-sdk';

// Initialize the API client
const api = new MicroSaaSAPI({
  apiKey: process.env.MSF_API_KEY,
  environment: 'production' // or 'development'
});

// Register a new user
async function registerUser(userData) {
  try {
    const response = await api.auth.register({
      email: userData.email,
      password: userData.password,
      name: userData.name
    });
    
    console.log('User registered:', response.data.user);
    return response.data.user;
  } catch (error) {
    console.error('Registration error:', error.message);
    throw error;
  }
}

// Log in a user
async function loginUser(email, password) {
  try {
    const response = await api.auth.login({
      email,
      password
    });
    
    // Store the tokens securely
    localStorage.setItem('accessToken', response.data.tokens.access);
    localStorage.setItem('refreshToken', response.data.tokens.refresh);
    
    console.log('User logged in:', response.data.user);
    return response.data.user;
  } catch (error) {
    console.error('Login error:', error.message);
    throw error;
  }
}

// Example usage
document.getElementById('registerForm').addEventListener('submit', async (e) => {
  e.preventDefault();
  const formData = new FormData(e.target);
  
  try {
    const user = await registerUser({
      email: formData.get('email'),
      password: formData.get('password'),
      name: formData.get('name')
    });
    
    // Auto-login after registration
    await loginUser(user.email, formData.get('password'));
    
    // Redirect to dashboard
    window.location.href = '/dashboard';
  } catch (error) {
    // Show error to user
    document.getElementById('errorMessage').textContent = error.message;
  }
});
