Built for Scale

Every feature designed for production SaaS workloads. From startup to enterprise, the same infrastructure scales with you.

01

Multi-Tenant Isolation

Complete request isolation between tenants. Per-tenant rate limits, quotas, and usage tracking. Your customers' data never mixes, even at scale.

02

Usage-Based Billing

Track every token, every request, every model. Export detailed usage data to your billing system. Support for tiered pricing, overages, and custom contracts.

03

Intelligent Routing

Route requests to the optimal model based on cost, latency, and capability. Automatic failover when providers experience issues. Your users never see downtime.

04

Real-Time Analytics

Per-tenant dashboards showing usage patterns, costs, and performance. Export metrics to your observability stack. Alert on anomalies before they become problems.

Architecture Overview

Three layers that handle everything between your application and AI providers.

Application Layer

Your SaaS Application

Your code makes standard API calls. No provider-specific SDKs, no vendor lock-in. Switch providers without changing application code.

Gateway Layer

AI API Gateway

Request routing, caching, rate limiting, and usage tracking. Tenant isolation and security. Real-time analytics and cost optimization.

Provider Layer

AI Model Providers

OpenAI, Anthropic, Google, Meta, and dozens more. The gateway handles provider-specific APIs, so your application doesn't have to.

Usage-Based Billing

Turn API costs into revenue with flexible billing models.

$

Per-Token Pricing

Charge customers per token used. Support different rates for different models. Pass through provider pricing or set your own margins.

Tiered Subscriptions

Include AI usage in subscription tiers. Higher tiers get more tokens, better models, or priority routing. Upsell power users automatically.

%

Markup & Resell

Add your margin on top of provider costs. Bundle AI with your core product. The gateway tracks exact costs so you always know your margin.

Integration

Simple Integration

One API endpoint. One SDK. All AI providers. Your application code stays clean and provider-agnostic.

• Automatic retry with exponential backoff
• Circuit breaker for provider failures
• Request/response logging for debugging
• Prometheus metrics export
// Your application code const response = await gateway.chat({ model: "gpt-4-turbo", messages: [ {role: "user", content: "Hello"} ], tenant: "customer-123" }); // Gateway handles: // - Provider routing // - Rate limiting // - Usage tracking // - Cost attribution

Common SaaS Patterns

How successful SaaS products integrate AI with production gateways.

AI-Powered Content Platform

A content creation SaaS offers AI writing assistance to thousands of users. The gateway provides per-user rate limiting, content moderation, and usage tracking. Users on higher tiers get access to more capable models. The platform tracks token usage in real-time and bills customers monthly based on actual usage.

Customer Support Automation

A helpdesk platform embeds AI-powered response suggestions. The gateway routes simple queries to fast, cheap models and complex questions to premium models. Usage is tracked per organization, enabling accurate billing. Automatic caching reduces costs for common questions by 60%.

Developer Tools Platform

An IDE plugin offers AI code completion. The gateway provides low-latency streaming responses, handles provider failures gracefully, and tracks usage per developer. Enterprise customers get dedicated model access and custom fine-tuned models through the same gateway.
