Why OneAPIKey

The billing, observability, and routing layer your stack already needed.

You focus on the product. We handle credentials, failover, metering, and inflation-indexed pricing across every major AI vendor.

One key, every provider

Drop in our key instead of juggling accounts at OpenAI, Anthropic, Google, ElevenLabs and dozens more.

Smart routing & fallbacks

Automatic failover between providers keeps your app up when one vendor has a bad day.

Transparent per-token pricing

We show upstream cost, our markup, and your effective unit price — no hidden fees, no lock-in.

Usage you can actually read

Real-time dashboards, cost forecasts, and per-key analytics so you know exactly what drives spend.

Server-side secrets

Upstream credentials never leave our servers. Your users never handle raw provider keys.

Drop-in compatible

OpenAI-compatible endpoints mean your existing SDKs work. Just swap the base URL.

Two clicks to production

From signup to first API call in 90 seconds.

No provider onboarding. No credit cards across three vendors. No leaking keys into users' hands. Just a URL, a key, and your code.
