# API Keys General Availability

API keys are now generally available as of April 6th. Part of the [machine authentication](https://clerk.com/docs/machine-auth/overview.md) suite, API keys let your users create credentials that delegate access to your application's API on their behalf.

## Pricing

Billing is now active. Each month includes a free allocation:

- 1,000 key creations, then `$0.001` per creation
- 100,000 key verifications, then `$0.00001` per verification
