ChainCatcher 消息，Alchemy 宣布推出一套面向 AI 代理的自主支付系统，允许 AI 代理通过链上钱包在 Base 网络上以 USDC 自动购买算力积分，并访问区块链数据服务，包括查询链上数据、NFT 持有情况、多链钱包余额及实时代币价格，无需人工干预。
该系统采用 Coinbase 的 x402 支付标准，将 HTTP 402 Payment Required 响应转化为自动结算触发器，实现机器间交易。代理账户最低可充值 1 美元 USDC，积分耗尽后系统自动发起支付请求并续充。
Alchemy CEO Nikil Viswanathan 表示，该系统面向构建自主 DeFi 代理、投资组合管理机器人等链上应用的开发者。Robinhood Crypto、Uniswap、Aave 等主要加密应用已依托 Alchemy 运行，AI 代理现可自主接入同一基础设施。
