SparxSolver API

Private testing server. Access is invite-only: you can sign in with Google only if the admin has invited your account.

Invite only

There is no public sign-up. The admin invites a Google account by email; the first sign-in with that account creates the user.

Your account

See your credit balance, recent credit history and signed-in devices, and sign out everywhere.

Audited

Sign-ins, invites, credit changes and admin actions are written to a tamper-evident audit log.
