Introduction
What is Nozle and who is it for
Nozle is an AI billing and margin intelligence platform. It gives AI companies usage-based billing, real-time entitlements, and per-customer margin visibility in a single integrated stack.
Who is Nozle for?
Nozle is built for AI companies that:
- Bill customers based on API calls, tokens, compute time, or other usage metrics
- Need real-time visibility into per-customer and per-model costs
- Want feature gating and usage limits without building entitlement logic from scratch
- Use Stripe for payments and need managed checkout flows
Key capabilities
| Capability | What it does |
|---|---|
| Usage-based billing | Meter any event, aggregate in real time, and invoice automatically |
| Real-time entitlements | Feature gates and usage limits evaluated at the edge with sub-100ms latency |
| Margin intelligence | Per-customer, per-model cost tracking so you know your true margins |
| Stripe checkout | Embedded checkout and subscription management with no custom Stripe code |
Architecture
Nozle is built around two layers:
-
Nozle API -- The backend that handles Stripe checkout, margin analytics, entitlement evaluation, and usage event ingestion. Runs at
api.nozle.app. -
SDKs -- Client and server libraries that connect your application to Nozle.
You interact with Nozle through the SDKs or REST API -- all the complexity of billing, entitlements, and margin lives behind a single API surface.
SDKs
Nozle ships three SDKs:
@nozle-js/react-- 25+ billing components and hooks for React apps. Checkout buttons, usage meters, plan selectors, and a full billing portal out of the box.@nozle-js/node-- Server-side billing operations and event tracking for Node.js. Report usage events, check entitlements, manage customers.nozle-sdk(Python) -- Server-side billing for Python backends. Same capabilities as the Node SDK.
