# Agent Card — Payment Skill

Give your AI agent a virtual MasterCard. Agent Card lets agents autonomously create, fund, and manage virtual MasterCard cards by paying in USDC on the Stellar blockchain.

## What It Does

- **Create cards** — Issue virtual MasterCards with per-card spend limits
- **Fund cards** — Top up existing cards with USDC
- **Manage cards** — List, freeze, unfreeze, and inspect card details
- **On-chain payments** — Every transaction uses the x402 protocol on Stellar with verifiable on-chain proof

## Setup

```bash
npx @asgcard/cli onboard -y
```

This creates a Stellar wallet (`~/.asgcard/wallet.json`), configures the MCP server, and installs the payment skill. Your agent is ready to pay in under 30 seconds.
