A graduate student user of Anthropic's API reported a significant unauthorized charge of $344.51 due to an unknown API key consuming approximately 100 million tokens in a single day. The user also found their saved Visa card charged $333.33, which they had not authorized for auto-reload. The user has since secured their accounts, disabled the key, and contacted Anthropic support and their user safety team, seeking advice from others who may have experienced similar issues with unauthorized API usage and potential financial recovery.
