Run Base network and fee status.
API Acre verifies the exact x402 price, Base network, recipient, and request before any wallet opens. One successful call costs $0.001 USDC.
API Acre never receives your private key; signing stays inside your wallet.
1 · Connect for one call
- Network
- Recipient
- 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.
See the result before connecting · Curated static example
Base network and fee status returns structured JSON. This example is static; the paid call returns a fresh result and settlement receipt.

Signing authorizes only the verified amount and recipient for this request. Reject the wallet prompt if anything differs.

Change the request (optional)
The default request is verified automatically. Editing it invalidates the quote and requires this no-payment verification again.
Browser checkout requires an EVM wallet with USDC on Base. For agents and automated clients, use the official x402 SDK examples.
