Website Registration

What happens after you register?

Six steps from this form to your first live login. Plain English, no surprises.

  1. 1
    Register your website

    Submit this form — website details, owner contact, and the $999 setup payment.

  2. 2
    Verify your email

    We email a verification link to the owner address. Click it to activate your account.

  3. 3
    Receive your API keys

    You get two site_keys — one for sandbox (free), one for production.

  4. 4
    Test login flow in sandbox

    Run our 15-minute quickstart against the sandbox key on localhost. No billing, no risk.

  5. 5
    Configure your callback URL

    Tell us where to redirect users after login. HTTPS in production; localhost is fine in sandbox.

  6. 6
    Go live and start receiving registrations

    Swap to your production site_key. From here it's $0.05 per new registration, capped at $499/mo.
