The x402 concept has recently gained popularity in various communities. The reason behind this popularity is that the x402 protocol is the only standardized solution currently available on the market that addresses the pain points of the API economy in the AI era. It seamlessly integrates the advantages of encryption into machine-to-machine interactions, providing AI agents with a native, permissionless, decentralized payment channel that requires no KYC. Consequently, it has become a popular new narrative tag.

While the initial wave of funding has receded, there’s no shortage of more solid, construction-focused projects emerging from the right sectors. Therefore, Odaily Planet Daily will review the hottest x402 concept projects across various ecosystems below for your quick understanding.

Introduction to the x402 Protocol

The x402 protocol is an open payment protocol developed by Coinbase. Its core function is to enable AI agents to autonomously complete payments and transactions without human intervention. Through x402, AI agents can pay for services on multiple blockchain networks using stablecoins, with the advantage of instant settlement, eliminating the complex processes of account registration, subscription activation, and API key configuration.

HTTP 402 is a network status code indicating “payment required,” but it has long been rarely used in practice. The x402 protocol exploits this status code: when an AI agent sends an API request, the server returns an HTTP 402 status code with the message “payment required to continue.” The AI agent recognizes this message and automatically pays the corresponding fee in stablecoins. The specific process is as follows:

When an AI agent attempts to access paid services such as news, APIs, and data, the server will return an “HTTP 402 Payment Required” status code. This response not only includes a “payment required” notification but also includes key information such as the payment method, payment amount, and recipient’s wallet address. The AI agent generates a transaction with the corresponding amount based on the information provided by the server, adds a digital signature, and sends it back to the server; The server passes the transaction to the Facilitator, who verifies the payment validity and completes the transaction on the blockchain. After the payment is completed, the server will open access to the paid service to the AI agent. Base Ecosystem PING
