Aptible Auth API
The Aptible authentication and identity service at auth.aptible.com. A HAL+JSON API exposing organizations, sessions, tokens, OAuth clients, users, U2F trusted facets and SSH key pre-authorizations, plus the RSA public key used to verify the JWTs it issues. This is where the bearer token consumed by the Deploy API comes from. No OpenAPI is published for this surface; the HAL root is the discovery document.
