Payment Redefined x402 Protocol and AI Autonomous Payments

x402: Enable AI with automatic payment capabilities

The open-source x402 protocol developed by the Coinbase team awakens HTTP status code 402 (Payment Required) and integrates it into the blockchain payment system, allowing AI agents to automatically complete payment processes when performing tasks without human intervention, achieving true self-economic behavior.

The combination of Payments MCP and AI wallet

With the Multi-Chain Payments (MCP) system, AI can not only manage its own cryptocurrency wallet but also automatically authorize payments when needed, eliminating the cumbersome steps of users logging in and entering information, making AI more like an independent intelligent entity with an economic persona.

Base network drives ecosystem explosion

The x402 protocol relies on the open-source network ecosystem of Base, allowing developers to freely create on-chain applications and integrate AI, payment, and DeFi. Recent data shows that the transaction volume on the Base network surged by 1560.1% within seven days, with a dramatic increase in active users, highlighting the market’s high expectations for the innovative potential of AI automatic payment.

$PING token: Pioneer of AI commercialization

$PING, as the first token issued on the Base network and utilizing the x402 protocol, has become a symbol of AI payment autonomy. From October 23 to 24, 2025, the price of $PING surged 20 times in a short period, with a market capitalization exceeding 80 million dollars, marking a new chapter for AI in the on-chain economy.

AI Intelligent Agents Move Towards Economic Entities

The emergence of $x401 and $PING is not just a technological breakthrough, but an important sign of the transformation of intelligent tools into economic entities. AI no longer merely executes commands but is able to spontaneously complete value exchanges, driving the vigorous development of the Web3 intelligent economy.

Summary

The rise of x402 protocol and $PING is not only an evolution of blockchain applications but also a milestone in the commercialization of AI, allowing intelligent agents to move beyond mere instruction levels and complete value exchanges.
