Coinbase Business has introduced a payment feature designed to let companies accept purchases made by artificial intelligence agents, extending its business platform into an early market for machine-to-merchant commerce.
The system uses Coinbase Payments and the x402 open payment standard, allowing software agents to request a product or service, receive structured payment instructions and settle a transaction on a blockchain network. Payments are generally completed in USDC on Base, Coinbase’s Ethereum layer-2 network, according to the company’s announcement.
The launch gives merchants using Coinbase Business a way to serve AI-driven customers alongside human buyers without building a separate payments stack. Early applications are concentrated in digital services that software can consume directly, including cloud computing, domain registrations, data access and API credits.
Such purchases are a natural starting point for autonomous software. An AI agent seeking additional computing capacity or access to a paid dataset can make a small, defined purchase without requiring a person to enter card details, approve an invoice or manage a subscription. Blockchain settlement and stablecoins are suited to these transactions because they can be executed programmatically at any hour and in amounts too small to fit comfortably into conventional card-payment systems.
Coinbase builds x402 payments into business accounts
Coelho-Prabhu, head of Coinbase Business, said the new capability is integrated into existing Coinbase Business accounts. Merchants can establish a payment process for AI clients while retaining their existing workflow for customers acting directly.
The payments system relies on x402, a standard named after HTTP’s 402 “Payment Required” status code. The protocol is intended to let websites, services and APIs ask for payment as part of an automated web request. Rather than redirecting a customer to a checkout page, a service can return machine-readable terms that software can evaluate and pay.
That structure could reduce friction in services sold by usage rather than through monthly plans. A developer tool, for example, could charge an agent for a single query, a limited amount of storage or a small package of computing time. The transaction can settle before access is delivered, giving service providers a way to charge automated customers without extending credit.
Coinbase said its agents can use structured data communications to complete purchases and settle them on networks including Base. USDC, a dollar-pegged stablecoin issued by Circle, is the typical settlement asset for the system.
Coinbase has been developing around x402 for several years, Coelho-Prabhu said. The company previously released Coinbase for Agents and a developer kit intended to help builders integrate x402 payments into online services. The Business rollout moves those tools closer to a merchant-facing product, where companies can accept payments rather than merely equip agents to make them.
Digital infrastructure is the first test case
The initial user base is likely to remain concentrated in services that have clear digital delivery and measurable consumption. Cloud storage, web hosting, domain services, compute resources and paid APIs can all be purchased and supplied automatically, with fewer of the disputes, shipping constraints and identity checks involved in physical commerce.
That makes the model more immediately practical for software businesses than for retailers selling goods that require delivery, returns or age verification. A payment agent may be able to buy an API credit in seconds, but purchasing a physical product creates questions around delivery addresses, consumer protections, authorization and liability if the agent acts outside its owner’s instructions.
The rollout also arrives as AI companies are experimenting with software agents that can perform multistep tasks, from research and coding to booking services and managing business workflows. Payments are a limiting component of that model: an agent can identify a service it needs, but cannot complete a purchase autonomously if it lacks access to a payment method designed for programmatic use.
Stablecoin settlement offers one solution, provided that a merchant and the agent’s operator are willing to use compatible wallets and payment infrastructure. The model shifts payment authorization away from a cardholder approving each transaction and toward rules set in advance, such as spending limits, approved vendors or permitted service categories.
Base documentation sees increasing agent traffic
Coinbase said automated agents accounted for about 53% of web traffic to Base blockchain documentation in June. The figure indicates that software tools are already interacting with technical resources used to build applications on the network, though documentation visits do not necessarily translate into commercial payments.
Base’s low transaction fees are part of its appeal for this type of activity. Agent-driven purchases may involve many small payments for software services, and transaction costs can become prohibitive if fees approach the value of the item being purchased. Layer-2 networks process transactions away from Ethereum’s main chain before posting compressed data back to it, a design intended to lower costs and increase throughput.
The company marked the rollout alongside the first anniversary of Coinbase Business, which began operating in June 2025. Coinbase said the division has reached roughly 5,000 clients and processed about $1 billion in combined payments and trading volume with a 12-person team.
Those figures cover the Business operation more broadly and do not indicate how much activity comes from AI-agent payments, which remain an early-stage product category. Coinbase’s announcement places the feature within a longer-term effort to establish payment rails for autonomous software rather than presenting machine commerce as a mature source of transaction volume.
For merchants, the immediate question is less whether AI agents will replace ordinary customers than whether automated clients become a meaningful new source of demand for digital services. Coinbase’s system gives businesses using its platform a way to test that demand with stablecoin settlement, while x402 provides a common format for agents and online services to communicate payment terms.
