x402 marketplace

x402 is an open standard for paying for a web request with stablecoins: the service answers "402 Payment Required" with a price, the client pays in USDC and gets the result. Kawase's plan is to let the agent find and pay for services from Circle's x402 catalog on your behalf, strictly inside a budget:

• a separate marketplace wallet whose balance is the hard cap,
• limits per call, per session and per day, set by you,
• every purchase shown with its price, the service and the result.

Circle's catalog lists mainnet services only, so the marketplace is planned for mainnet and is not on testnet. It is coming: not available in the app yet.
