x402 is an open standard that puts stablecoin payments directly into web interactions by revitalising the original HTTP “402 Payment Required” status code.

X402是一个开放标准，它通过振兴原始的HTTP“ 402付款必需”状态代码将Stablecoin付款直接付给Web交互。

This allows developers and AI agents to pay for services and software with stablecoins over HTTP to simplify the payment process.

这使开发人员和AI代理可以通过HTTP上的稳定币支付服务和软件，以简化付款过程。

With a few lines of code, x402 provides built-in authentication, automatic settlement, and integration into the existing web infrastructure.

有几行代码，X402提供了内置的身份验证，自动结算和集成到现有的Web基础架构中。

It also enables instant monetisation and autonomous transactions, allowing businesses and agents to exchange value as they exchange data.

它还可以立即获利和自主交易，使企业和代理商在交换数据时交换价值。

The launch of x402 is supported by collaborators such as AWS, Anthropic, Circle, and NEAR.

X402的推出得到了AWS，Anthropic，Circle和附近的合作者的支持。

The workflow includes the client initiating requests for access to a resource, the server issues a 402 Payment Required response, the client sends a signed payment, and upon verification by a payment facilitator like the Coinbase x402 Facilitator service, the server delivers the requested data.

工作流程包括客户启动对资源访问的请求，服务器颁发了402付款所需的响应，客户发送签名付款，以及通过付款辅助器（如Coinbase X402促进者服务）进行验证后，服务器提供了请求的数据。

Developers can use services such as the Coinbase x402 Facilitator to easily integrate stablecoin payments into their offerings with minimal coding.

开发人员可以使用Coinbase X402促进器等服务来轻松将Stablecoin付款集成到其产品中，并将其与最少的编码相结合。

This capability grants AI systems the ability to perform real-time, autonomous transactions, facilitating "scenarios" such as autonomous cloud compute, market intelligence, prediction markets, and AI-driven creative tools.

该能力授予AI系统能够执行实时，自主交易的能力，促进“方案”，例如自主云计算，市场智能，预测市场和AI-DEREAD创意工具。

Coinbase Developer Platform engineering head Erik Reppel said: "We built x402 because the internet has always needed a native way to send and receive payments—and stablecoins finally make that possible. Just like HTTPS secured the web, x402 could define the next era of the internet; one where value moves as freely and instantly as information. We’re laying the groundwork for an economy run not just by people, but by software—autonomous, intelligent, and always on.”

Coinbase开发人员平台工程负责人Erik Reppel表示：“我们建立了X402，因为互联网一直需要一种本地方式来发送和接收付款的方式，而StableCoins终于使这一切成为可能。就像HTTPS一样，就像HTTPS一样，X402可以确保互联网的下一个时代的定义，而不是按照互联网的范围来定义一个互联网；而不是像我们一样自由地移动了一个，而不是像我们那样付出了本方面的范围。永远继续。”

Last month, Coinbase expanded partnership with PayPal, enabling users to buy, sell, and trade PYUSD without platform fees to promote the adoption of the PayPal USD (PYUSD) stablecoin.

上个月，Coinbase扩大了与PayPal的合作伙伴关系，使用户能够无需平台费用即可购买，出售和交易Pyusd，以促进PayPal USD（PYUSD）Stablecoin的采用。
