Start with 1,000 free usage units each month after you verify your email. Account actions never consume your allowance. Credit purchases are not live until prepaid checkout is enabled; POST /v1/account/checkout returns 503 until then. Signup creates a customer only — no metered subscription.
Verify the mailbox to unlock the free tier and to recover a lost key. We never attach a wallet just because an email string matches.
Paste an existing key to check remaining free units and prepaid credits. Checkout amount is set by the server, not this page.
PREPAID_ENABLED. The top-up amount comes from the server (PREPAID_TOPUP_CENTS), not this page. Credits appear only after a verified Stripe payment.
