Everything you need to monetize

Built-in tools for monetization, access control, and user management

5-Minute Setup

Install our SDK, add one line of code, and you're ready to monetize. No complex configuration or infrastructure needed.

Hosted Checkout

Payments are powered by Stripe Connect. Developers act as the Merchant of Record for transactions with end users. BillAI provides monetization and access control infrastructure and charges a platform fee.

Access Control

Feature gating built-in. Control who can access what with boolean or usage-based features. Works with any plan structure.

How it works

Three simple steps to start monetizing your app

1

Create App & Pricing Plans

Sign up, create your app in the dashboard, and define your pricing plans with features.

2

Install the SDK

$ npm install @billai/sdk
3

Check Access

Use access.check() to gate features based on user plans.

How payments work

Simple, transparent payments powered by Stripe Connect

1

Purchase

End user purchases access to a developer's digital service

2

Processing

Payment is processed by Stripe (developer is the Merchant of Record)

3

Platform Fee

BillAI platform fee (7% default) collected via Stripe Connect application fees

4

Payout

Remaining funds are paid out to the developer via Stripe

Simple SDK, powerful control

Our SDK exports two focused classes: Billing for payment flows and AccessControl for feature gating, plus typed errors for explicit error handling.

  • Boolean features
    Simple on/off access control
  • Usage-based features
    Limit API calls, storage, or any metric
  • Automatic upgrade URLs
    Redirect denied users to checkout
  • Retries + typed errors
    Automatic retries with explicit error handling
access-control.ts
import { AccessControl } from '@billai/sdk';

// Initialize with your API key
const access = new AccessControl({
  apiKey: process.env.BILLAI_API_KEY!,
  appId: 'app_your_app_id',
});

// Check if user has access to a feature
async function handlePremiumFeature(userId: string) {
  const result = await access.check(userId, 'premium_feature');
  
  if (!result.granted) {
    // Redirect to upgrade page
    return { upgradeUrl: result.upgradeUrl };
  }
  
  // User has access - proceed with feature
  return { success: true };
}

// Usage-based feature with increment
async function handleAPICall(userId: string) {
  const result = await access.check(userId, 'api_calls', {
    increment: 1, // Count this usage
  });
  
  console.log(`Usage: ${result.usage}/${result.limit}`);
  return result.granted;
}
