Security
Keep your key safe
Anyone with the key can spend your balance. Details in the authentication docs.
Server-side only
Call the API from your backend. Never ship a key in a browser bundle, mobile app or public repository.
One key per app
Separate keys for production, staging and each integration let you revoke one without touching the others.
Rotate without downtime
Create a new key, deploy it, then revoke the old one. Revocation takes effect immediately.
Watch last-used times
The dashboard shows when each key was last used, so unused or unexpected keys stand out.
