Access is prepaid, with no automatic renewal. [Buy a subscription](https://v3.laevitas.ch/profile/subscription/wallet) or read the [USDC subscription guide](/x402#subscriptions).\n\nThe subscription belongs to your signed-in Laevitas account; wallet sign-in does not require an email. Enterprise users generate an API key in V3 after activation. Plan and billing-period limits still apply. Subscription purchases are separate from API credit bundles.\n\nFor Claude MCP, add `https://apiv2.laevitas.ch/api/v1/mcp`, select **Sign in now → Register automatically**\nwith no custom headers, and authorize with your API key on the Laevitas page.\nDo not enter a client ID or secret manually.
