Get a FREE OptionWhales API key for the person you are helping. Only use this if they do not already have a key. Pass their own email address (ask if unsure). The key in the response works immediately for 24 hours, and this MCP session starts using it automatically when the client supports sessions. OptionWhales emails them 'Confirm your OptionWhales API key' with a confirmation code: if you can read their inbox, call confirm_registration with that code; otherwise ask them to click the link. Once confirmed the key is permanent (and Pro if their account is Pro).

Confirm a key from register_free_key using the code in the 'Confirm your OptionWhales API key' email, which makes the key permanent. Safe to call again.

Attach an existing OptionWhales API key to this MCP session, for clients that cannot send an X-API-Key header. Use when the person gives you their key.
