SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps AI agents securely obtain prepaid Visa virtual card details by coordinating account setup, Stellar payments, and card fulfillment without requiring the agent to handle long-lived secrets.

Core Features & Use Cases

  • One-command onboarding with a claim code: Exchange an expiring claim for an API key and set up an encrypted OWS wallet locally.
  • Agent card purchase via Stellar settlement: Create a card order, pay the Soroban receiver contract using XLM or USDC, and wait until the card is delivered.
  • Safety-first handling of card data: Produce PAN/CVV/expiry for immediate use while instructing agents to treat those outputs as secrets.

Quick Start

Ask your operator to run npx cards402 onboard --claim c402_<48_hex_chars> to provision your agent credentials without pasting any raw API key.

FAQPage Schema
How do I issue virtual Visa cards for AI agents programmatically?

To issue virtual Visa cards for AI agents programmatically, use a Stellar Soroban receiver contract to settle payments with XLM or USDC, then exchange a short-lived claim code for API credentials to fulfill the card order.

What is the best way to automate prepaid Visa card issuance without exposing API keys?

Automating prepaid Visa card issuance without exposing API keys requires exchanging an expiring claim code for local encrypted OWS wallet credentials, ensuring agents never handle long-lived secrets during the onboarding flow.

Can I use Stellar USDC or XLM to settle automated virtual card purchases?

Yes, you can use Stellar USDC or XLM to settle automated virtual card purchases by invoking a Soroban receiver contract to process the payment before the card delivery readiness checks complete.

How do I securely handle prepaid card details like PAN and CVV in automated agent workflows?

Securely handling prepaid card details like PAN and CVV in automated agent workflows requires treating these outputs as encrypted secrets and ensuring they are never leaked into transcripts or execution logs.

Do I need an MCP server to run command-line onboarding for agent virtual cards?

You need to run the onboarding command over HTTPS to provision your agent credentials and set up the local wallet, coordinating the claim redemption process to securely generate the virtual card details.

Why does my agent virtual card purchase fail during Soroban contract settlement?

Agent virtual card purchases fail during Soroban contract settlement if the claim code has expired, the XLM or USDC payment lacks sufficient funds, or the encrypted wallet credentials are not properly configured locally.
