MicroAuthDocs

Launch an API business in minutes — auth, rate limiting and metered billing, without touching your API traffic.

🔑

API key auth, done for you

Your customers create keys on your branded portal. The SDK authenticates every request from a locally cached snapshot — MicroAuth never sees your API traffic.

⏱️

Rate limiting & quotas

Per-customer RPS, monthly quotas and custom overrides are resolved and enforced at the edge of your own API, with no gateway to run.

💳

Metered, prepaid billing

Meter billable responses, deduct prepaid credits, and reconcile via Stripe or your own external billing system.

🧩

Integrate any stack

Use the drop-in FastAPI SDK, or call the SDK API directly from any language. Add credits from your own billing with a single endpoint.
