What is Sardis Cards?
Sardis Cards provides the financial infrastructure required for AI agents to make real-world purchases safely and efficiently. By integrating this capability into Openclaw Skills, developers can programmatically issue virtual cards with automated spending limits, merchant restrictions, and instant freeze capabilities. This skill bridges the gap between digital agents and the physical economy, ensuring that every transaction is monitored and secured against fraud or overspending.
The system emphasizes a security-first approach, where sensitive card data is masked by default and only revealed through secure endpoints when absolutely necessary. By utilizing Openclaw Skills for financial management, you can deploy procurement, marketing, or travel agents that operate within strict budgetary and category-based guardrails.
Sardis Cards Use Cases
- Automated SaaS subscription management and payment renewals.
- Budget-controlled cloud service spending across AWS, GCP, and Azure.
- Procurement agents purchasing office supplies and hardware within set limits.
- Marketing agents managing ad spend on platforms like Google Ads and Facebook.
- Travel agents handling flight and hotel bookings with category-specific restrictions.
How Sardis Cards Works
- The AI agent requests the creation of a virtual card with defined spending limits and allowed merchant categories.
- The Sardis API issues a new card and returns a masked version of the card data for tracking.
- When a purchase is required, the agent retrieves the full card details through a protected reveal process.
- Every transaction is vetted in real-time against per-transaction, daily, and monthly limits.
- Automated monitoring detects anomalies or rapid transactions, triggering an instant freeze if suspicious activity occurs.
