Billing runs through Polar, our payment provider. Top up, manage your card and download invoices at Polar's secure portal — card details never touch Sekreto.
Calls never expire. Failed calls (4xx/5xx) are never billed. Checkout is handled by Polar, our merchant of record — taxes included, receipt by email (use any address; your Sekreto account stays email-free). Your API key is rotatable from here — lost, leaked, or just cautious, rotate below and update your client config; your account number, balance, and history stay put.
Key rotated. The new key is shown once — the old key stopped working.
