Cardia

Cardia provides virtual payment cards for digital agents, enabling them to make purchases with strict controls. Key features: • Virtual cards with hard spending limits • Per-merchant scope restrictions • Real-time purchase authorizer • Control agent spending via CLI, MCP, or API • Support for LATAM currencies (ARS + USDT) This platform addresses the critical need for secure and controlled spending for digital agents. It allows users to connect their existing agents, such as Claude, ChatGPT, or Cursor, and assign them virtual cards with predefined monthly limits and specific vendor permissions. Every transaction is subject to these rules, ensuring that funds are only spent as intended. For transactions exceeding a user-set threshold, real-time approval requests are sent to the user's phone, requiring Face ID verification. Cardia ensures that spending controls reside within the app, not with the digital agent, offering a robust security layer even if agents are compromised. Users can instantly freeze or cancel any card and monitor all expenditures live from their mobile device. The system supports both 'Controlled' cards, restricted to specific merchants, and 'Open' cards, allowing purchases within a general limit. Ideal for teams and individuals managing digital agents who require precise financial oversight without needing physical cards or complex banking integrations. It empowers agents to handle subscriptions, APIs, and purchases autonomously while maintaining complete user control over every transaction.
