Visa Built a Payment Tool for AI Agents – Machine-to-Machine Commerce Now Has Infrastructure

Visa Crypto Labs has released an open-source command line interface tool that allows AI agents to execute financial transactions autonomously, without human intervention at the point of payment.

What the Tool Actually Does

The CLI is designed for developers building on large language models and other AI systems. It allows an AI agent to hold its own wallet, funded with stablecoins such as USDC or specialized digital assets, and spend from that wallet to acquire resources it needs to operate. API keys, cloud computing capacity, and data sets are the cited examples. The agent identifies the need, executes the payment, and continues operating without waiting for a human to approve the transaction.

According to information from Visa, the technical architecture uses account abstraction and smart contracts to give AI bots functional wallet infrastructure on-chain. That is a meaningful design choice. Account abstraction allows wallets to operate under programmable rules rather than requiring a private key signature for every transaction. It makes autonomous spending mechanically possible in a way that standard wallet structures do not easily support.

The tool is not unconstrained. Visa built a policy engine into the CLI that allows human owners to set spending limits, restrict transactions to whitelisted merchants, and apply expiration dates to the bot’s allocated budget. The agent operates autonomously within those parameters. It cannot exceed them.

Why a CLI and Not an API

The choice of format is deliberate. A command line interface integrates directly into the terminal-based environments where most AI agents are currently built, tested, and deployed. Releasing a CLI rather than a standard API removes a layer of abstraction that would slow developer adoption. It meets the tooling where the work is actually happening.

That developer-first framing is consistent with how infrastructure gets adopted in the AI space. Stripe followed the same logic when it released an agent-compatible checkout suite in late 2025. Visa’s CLI puts it in direct competition with that offering for developer mindshare at the infrastructure layer.

The Scale Argument

The strategic context behind this launch is a joint report published by Visa and Coinbase on March 15. The report estimates that autonomous agentic spending could represent over $500 billion in global transaction volume by 2027. That figure is directional rather than precise, but it establishes the commercial thesis Visa is building toward.

On March 14, Visa announced a partnership with Sky, the protocol formerly known as MakerDAO, to explore using the USDS stablecoin within this automated payment framework. That collaboration connects the CLI infrastructure to an existing stablecoin with significant on-chain liquidity and institutional familiarity.

The machine-to-machine commerce thesis is not speculative at this point. AI agents are already consuming paid API services, cloud resources, and data infrastructure. The current payment mechanism for most of that consumption is a human credit card attached to a developer account. Visa’s CLI is an attempt to replace that human-intermediated step with autonomous on-chain execution at scale.

Whether the $500 billion estimate proves accurate is a separate question. The infrastructure to support that volume is what Visa is building now.
