How it works
Fund your treasury
Send USDC or pathUSD to your treasury address on Base, Solana, or Tempo. Your balance is available instantly.
Issue cards
Create virtual payment cards backed by your treasury balance. Each card has its own spending limit, controls, and purpose.
Agents pay autonomously
Your agents use cards to pay for APIs via x402, AP2, or MPP protocols. Every transaction is tracked and auditable.
Supported protocols
| Protocol | Direction | Use case |
|---|---|---|
| x402 | Bidirectional | HTTP 402 payment-required flows:agent pays for API access |
| AP2 | Bidirectional | Agent-to-agent payments with spending mandates |
| MPP | Bidirectional | Micropayment streaming:pay-per-token, pay-per-call |
