Alter

The credential layer for apps and agents calling third-party APIs. Provider calls use authorized credentials. Every credential-use request passes policy checks and emits a terminal audit event.

Quickstart

Sign up, mint a key, and read a connected GitHub profile from application code. Under 10 minutes.
