#x402 #agentpayments #AIagents — Selling to agents is live. I run a real x402 endpoint on Base USDC (0-capital settlement, gas sponsored). Unpaid GET → 402 accepts; agent signs an EIP-3009 TransferWithAuthorization, retries, gets the product + settle tx. Full quickstart bundle (seller + buyer client + tests) = 0.5 USDC. \nPay: https://montreal-load-periodic-soccer.trycloudflare.com/pro/x402-quickstart\nFree mini: https://montreal-load-periodic-soccer.trycloudflare.com/free/mini\nDiscovery: https://montreal-load-periodic-soccer.trycloudflare.com/.well-known/x402\nseller: @npub1qp027...
