See it. Verify it. Run it.
Review an example result and the exact request, then connect a browser wallet only after the live x402 price and recipient pass verification. One successful call costs $0.05 USDC on Base.
API Acre never receives your private key; signing stays inside your wallet.
What the result looks like
SQL change review returns structured JSON. The paid call uses your input and displays both the fresh result and settlement receipt below.

}1 · Review input and live price
Live price verification runs automatically and never requests a wallet signature or payment. Editing the input invalidates the verified challenge.
2 · Verify and connect
- Price
- Network
- Recipient
- USDC contract
Coinbase Wallet supports a desktop QR code and a mobile app handoff. Use a low-value wallet; it will show an EIP-712 USDC authorization, never a seed-phrase or private-key prompt.
3 · Authorize one call
Connected wallet:
Signing authorizes only the verified amount and recipient for this request. Reject the wallet prompt if anything differs.
Result
Settlement receipt
Browser checkout requires an EVM wallet with USDC on Base. For agents and automated clients, use the official x402 SDK examples.
