Key Meter
API key management with built-in usage billing
Key Meter handles the full lifecycle of API keys for SaaS products — issuance, rotation, rate limiting, and usage-based billing. Connect your API gateway, define pricing tiers per endpoint, and let Key Meter handle metering, invoicing, and customer self-service without writing billing code.

The Problem
Sound familiar?
Building API key management and metering from scratch takes weeks away from the core product
Usage-based billing is theoretically simple but operationally complex to get right at scale
Customers abuse free tiers when there's no per-key rate limiting — and you only find out after the bill arrives
The Solution
Key Meter fixes this.
Key Lifecycle Management
Issue, revoke, rotate, and scope API keys via dashboard or API. Keys support custom expiry, IP allowlists, and endpoint-level permission scopes.
Usage Metering
Counts requests per key, per endpoint, and per time window with sub-second precision. Aggregates feed directly into billing calculations.
Usage-Based Billing
Define pricing rules (per-call, per-token, tiered, overage) and Key Meter generates Stripe invoices automatically at the end of each billing period.
How It Works
Set up in under 2 minutes. No complex configuration.

Frequently Asked Questions
Does Key Meter sit in the request path and add latency?
Key Meter offers two modes: synchronous (validates key on every request, adds ~2ms) and async (validates from cache, ingests usage events asynchronously). Most customers use async mode.
Can I use Key Meter without Stripe?
Key management and metering work independently of billing. You can use the usage data via API to drive invoicing in any payment system.
