// one paid request
Scroll through the complete x402 handshake. Arcon only owns the verification and settlement boundary—the rest remains yours.
Resource request
The resource server stays focused on its product. It declares a price and returns the standard HTTP 402 challenge.
await fetch(
"https://api.example/research"
);
Payment challenge
Network, asset, recipient, amount, and expiry travel as machine-readable payment requirements—not a checkout page.

Authorization
The agent authorizes an EIP-3009 USDC transfer. Arcon checks the signature, nonce, deadline, amount, and receiver.
Settlement
Arcon submits the authorized transfer and returns the onchain transaction hash to the protected resource.
Settlement final
0x8f2a7b…91c4
// facilitator surface

/supportedAdvertise x402 v2, exact EVM, Arc Testnet, and facilitator signers.
/verifyValidate an authorization against the resource server’s exact payment terms.
/settleBroadcast the USDC transfer and wait for a confirmed Arc receipt.
