📄 中文摘要
构建并部署了三个完全自主的API，AI代理能够发现这些API，自动支付USDC微支付并获取数据，整个过程无需人工干预。传统API需要订阅、API密钥、信用卡和账单管理，这对人类开发者来说是可管理的，但AI代理无法注册账户或处理账单。为了解决这一问题，采用了x402协议，使得AI代理可以直接支付使用API所需的数据，涵盖加密货币价格、股票数据、外汇汇率、网页抓取和AI摘要等功能。该技术栈、面临的挑战以及如何构建类似系统的步骤也进行了详细阐述。

I Built 3 APIs With 22 Paid Endpoints That AI Agents Pay For Automatically — Here's How (x402 + USDC on Base)
Three fully autonomous APIs have been built and deployed, allowing AI agents to discover them, make USDC micropayments, and retrieve data without any human involvement. Traditional APIs require subscriptions, API keys, credit cards, and billing dashboards, which are manageable for human developers but not for AI agents that cannot sign up for accounts or handle invoices. To address this issue, the x402 protocol was implemented, enabling AI agents to pay directly for the data they need. The APIs provide access to crypto prices, stock data, forex rates, web scraping, and AI summaries. The article details the tech stack used, the challenges faced, and how to build similar systems.
