Run EVM address inspection.

API Acre verifies the exact x402 price, Base network, recipient, and request before any wallet opens. One successful call costs $0.002 USDC.

USDC contract

No ETH gas needed. Connecting does not sign or pay. Coinbase Wallet supports desktop QR and mobile handoff without a browser extension. This EIP-3009 payment needs only the displayed USDC on Base—not ETH for gas—because the facilitator submits settlement. Reject any later prompt that differs from the verified amount or recipient.

Copy an exact-cap Agentic Wallet command

Running this command may automatically spend up to $0.002 USDC after Coinbase Agentic Wallet authentication and policy checks; copying it does nothing. npx --yes approves package installation. Use a separate low-value wallet and review the verified request before running it.

Alternative third-party AgentCash command

The first command checks without paying; running fetch may pay up to the same exact cap.

The default request is verified automatically. Editing it invalidates the quote and requires this no-payment verification again.
