x402 Payment Protocol

The x402 protocol is an open internet‑native payment standard that turns the long‑unused HTTP 402 Payment Required status code into a way for services, APIs, and software (including AI agents) to request and settle payments directly over the web using blockchain stablecoins.

The x402 payment protocol is the technical engine that allows CLAUDE_launch to function as an autonomous, AI-controlled platform. It essentially acts as the bridge between your conversational interaction with Claude and the technical execution on the Solana blockchain.

When you are ready to launch, you sign x402 payment. $USDC is required for this payment.
