Verify before signing

The checkout validates the Base network, USDC contract, amount, recipient, and requested resource.

Pay only per call

No prepaid balance or recurring plan. EIP-3009 lets the buyer authorize Base USDC without holding ETH for gas.

Keep control of the wallet

Signing stays inside your injected wallet. API Acre never asks for a seed phrase or private key.
