Autonomous AI agents are programs capable of making decisions and completing tasks without human intervention. According to Coinbase developers Kevin Leffew and Lincoln Murr, these AI agents could revolutionize Ethereum’s role in global commerce by becoming its "biggest power users." This transformation is expected to be driven by the revival of an internet standard from 30 years ago: HTTP 402, also known as "Payment Required." When combined with Ethereum Improvement Proposal 3009, this standard enables AI agents to send stablecoin payments automatically, paving the way for blockchain-powered automation.

How It Works Like a Vending Machine

To understand this concept, imagine a vending machine. An AI agent receives a payment request, signs a transaction, and sends the funds. Once the payment is confirmed, the service delivers the requested product or service—whether that is data, storage, or computing power. This process happens instantly, eliminating the need for traditional accounts or manual approvals. Essentially, it transforms APIs into services that can directly verify a wallet’s balance and process payments in a single step.

Why Ethereum Fits the Job

Ethereum’s strengths make it ideal for this use case. Its settlement system processes payments instantly without the delays and intermediaries typical of traditional finance. Instead of waiting days for invoices or dispute resolutions, Ethereum handles everything on the spot. Stablecoins further enhance this process by removing the price volatility common with other cryptocurrencies. As the developers note, AI agents require "atomic payments, programmable policies, and composable wallets." Ethereum combined with stablecoins provides exactly these capabilities, making it the natural platform for this emerging technology.

Early Examples Show the Potential

This shift is already underway. Hyperbolic Labs has integrated HTTP 402 into its large language model AI, allowing it to autonomously purchase the data it needs. Prodia Labs uses the standard to pay for the creation of images and videos automatically. Coinbase has developed its own version called the "x402 payments protocol," which is available on GitHub for other developers. By linking multiple services in a chain, AI agents could eventually form complete economic loops without human involvement. This trend aligns with existing developments in crypto markets, where AI agents trade cryptocurrencies by analyzing market data and executing orders in real time. If AI agents can also pay for services directly, their role could expand into areas such as transportation, content creation, and data management. For example, self-driving taxis could autonomously pay for charging stations, and content-producing AI could instantly store its work. If adoption accelerates, AI agents could become Ethereum’s largest power users, driving blockchain technology into mainstream applications far beyond cryptocurrency alone. At the time of writing, Ethereum is priced at $4,710.12.
