FAQs

The Auth API is a comprehensive platform that helps you secure, monitor, and monetize your API. We handle API key management, authentication, rate limiting, and usage tracking so you can focus on building your core product. Whether you’re launching your first API or scaling an existing one, we provide the infrastructure to protect your service while creating new revenue opportunities through usage-based billing and customer insights.

Most developers complete basic integration in under 30 minutes. Unlike gateway solutions that require routing all your traffic through our servers, The Auth API works through simple authentication calls – just add our SDK to your existing API endpoints. No infrastructure changes needed. We provide clear documentation, code samples for popular frameworks, and our team offers free consultation calls to ensure smooth integration.

The key difference is infrastructure requirements. API gateways require you to route all traffic through their proxy servers, which adds complexity and potential latency. The Auth API is authentication-first – we integrate directly with your existing API through simple authentication calls. You keep control of your infrastructure while gaining powerful features like:

  • Native Stripe integration for automated billing
  • Usage-based metering in your business units (AI tokens, transactions, etc.)
  • Organisation management for customer segmentation
  • Real-time usage tracking without traffic routing

Absolutely – this is one of our core strengths. The Auth API offers flexible usage-based billing that works with your native business metrics. Whether you charge per AI token, API call, data point, or transaction, we automatically track usage and report to Stripe for seamless billing. Our system supports:

  • Custom usage units that match your business model
  • Automatic Stripe integration for metered billing
  • Real-time usage limits and monitoring
  • Organisation-based billing for B2B customers
  • White-label customer portals for self-service
We provide multi-layered security designed for today’s threat landscape where 78% of API attacks come from authenticated users. Our protection includes:

  • Real-time monitoring – alerts for unusual activity patterns
  • Business logic protection – preventing authenticated users from exploiting monetization rules
  • API key lifecycle management – automated expiration, rotation, and deactivation
Our authentication-first approach means we can detect threats at the API key level before they impact your core infrastructure.
We provide detailed, actionable insights into how your API is being used:
  • Customer-level analytics – individual usage patterns and behavior
  • Revenue tracking – usage-based billing insights and growth metrics
  • Security monitoring – threat detection and anomaly alerts
