Getting started

Authentication.

Include your API key as a Bearer token in the Authorization header with every request.

API keys

Generate a key from the dashboard. Every key has the form ax_live_ followed by 32 hex characters (128-bit entropy). Keys bill against your plan, count toward rate limits, and can trigger webhooks. Treat them as secrets and rotate them from the dashboard.

Treat keys as secrets.

Keys are shown once at creation. Store them server-side; never ship a live key in client code. Rotate from the dashboard if exposed.
