🤖 Agents Pay Their Own Bills
**AI agents can now pay for services automatically using USDC** — no human intervention, no credit cards, no sign-up forms.
Circle's Agent Stack enables autonomous agents to:
- Hold their own wallets and manage budgets
- Discover and pay for services they need (like voice calls or APIs)
- Complete transactions for as little as $0.007 USDC
- Continue workflows without breaking at paywalls
At the AI Agents Summit Berlin hackathon, developers built 25 projects demonstrating this "agentic economy" in action:
- **Proprietor**: An agent-run business that earns revenue, pays suppliers, and manages margins
- **BytomicProxy**: Pay-per-request API access for agents
- **402Cards**: Agents buying physical items on mainnet
- **giftr**: Local marketplace where agents browse and purchase gifts
The pattern is clear: agents are evolving from generating text to **completing actual work** — researching prospects, placing calls, paying for resources, and returning receipts.
Circle also supports **x401**, a new protocol for verified identity in agent transactions, complementing x402 for payments.
