Autonomous pay-per-use infrastructure that transforms HTTP 402 Payment Required into a Web3-native payment layer.
Currently live on Devnet. Powered by $402G.
๐ Integrated with Coinbase x402 Protocol
402Gate brings the missing link between Web2 and Web3 turning any HTTP request into a pay-per-use transaction. No accounts, no subscriptions just instant access after micropayment.
Built on Solana, it allows users and AI agents to pay per request using $402G, USDC, or SOL verified trustlessly in seconds.
402Gate is built on top of the x402 Protocol by Coinbase, implementing the HTTP 402 Payment Required standard for Web3-native micropayments.
