IMPORTANT: Call from the back-end.

When a user wants to take custody of their Mintable Wallet, you can call this endpoint to initiate the process. When you call the endpoint, we will send an email to the user, with an OTP which will have to be provided to access the private key of the wallet. This flow ensures that the request was indeed initiated by the user, since we will be sending this email from our systems. In order to access the private key, both the OTP sent to the user, and the request ID returned by this endpoint will have to be provided.

This endpoint should always be called from your backend to prevent any potential spamming or exposing your private API key.
