Visa Launches a Payment Tool for AI Agents: Autonomous Commerce Is Here
📋 En bref (TL;DR)
- Visa CLI: a command-line tool that allows AI agents to make card payments without an API key
- Visa Agentic Ready: 21 European banks (Barclays, HSBC, Revolut, Santander) are testing AI-initiated payments
- MCP Server: Visa publishes an open-source server on GitHub so developers can integrate payments into their AI agents
- Race is on: Mastercard (Agent Pay), Stripe (MPP), PayPal and Coinbase (x402) are also launching their solutions
- Massive market: agentic commerce could generate $1 trillion in the United States by 2030 (Morgan Stanley)
What if your AI assistant could pay on your behalf? That is exactly what Visa is making possible with a series of announcements in March 2026: a command-line tool for AI agents, a European banking program, and an open-source server for developers.
The payments giant is not just following the trend — it is laying the rails for a new economy where AI agents carry out transactions autonomously.
Visa CLI: when AI pays via the command line
On March 18, Visa Crypto Labs launched Visa CLI — the first experimental product from Visa’s crypto lab. It is a command-line tool that allows AI agents to make card payments directly from a terminal.
The key feature: no API key is required. A deliberate choice, since AI agents can inadvertently expose sensitive information. Authentication is handled through GitHub OAuth.
In practice, an AI agent can:
- Pay for an image generation service on demand
- Purchase access to paid databases (market data, analytics)
- Settle cloud infrastructure costs in real time
Cuy Sheffield, head of Visa’s crypto division, calls it “command-line commerce” — a new era where AI agents carry out transactions without human intervention at every step.
21 European banks test AI agent payments
On the same day, Visa launched Visa Agentic Ready, a program that gives banks a framework for testing payments initiated by AI agents.
21 banks are participating in the first phase in Europe:
- United Kingdom: Barclays, HSBC UK, Nationwide
- Germany: Commerzbank, DZ Bank
- Fintech: Revolut
- Spain: Banco Santander
- Austria: Raiffeisen Bank International, Erste Bank
- Italy: Nexi Group
- + Alpha Bank, Bank Leumi, Banca Transilvania, Bank of Cyprus, etc.
The framework is built on three security pillars:
- Tokenization: the actual card number is replaced by a unique code, invisible to the AI agent
- Biometric authentication: fingerprint or facial recognition to validate the link between the token and the cardholder
- Configurable limits: the bank and the consumer set spending caps and usage conditions
An open-source server for developers
Visa also published an MCP Server as open source on GitHub. This server allows developers to integrate Visa payments into their AI agents in a matter of hours — instead of days or weeks of development.
The Acceptance Agent Toolkit, built on top of this server, even enables non-developers to generate invoices, create payment links, and access analytics using natural language.
More than 100 partners are already working within the program, with 30+ actively developing in the sandbox. Hundreds of AI agent-initiated transactions have already been processed in production.
Visa’s prediction: millions of consumers will use AI agents to make purchases by the 2026 holiday season.
The race for agentic payments
Visa is not alone. The entire payments industry is positioning itself in this new market:
Mastercard (Agent Pay) completed on March 2 the first European transaction carried out by an AI agent in a regulated banking environment, with Banco Santander. The system relies on a “Know Your Agent” framework and agentic tokens.
Stripe launched on the same day as Visa CLI the Machine Payments Protocol (MPP), co-developed with Tempo — a blockchain specialized in stablecoins. MPP supports cards, stablecoins, wallets, and even Bitcoin Lightning.
PayPal has offered “Agent Ready” since early 2026 and integrated Google’s Universal Commerce Protocol (UCP) — Google’s AI agents will be able to pay via PayPal.
Coinbase launched the x402 protocol with Cloudflare, which enables stablecoin micropayments embedded directly into HTTP requests.
The connection to crypto and stablecoins
The link runs deeper than it appears:
- Visa CLI was developed by Visa Crypto Labs and supports the x402 protocol (Coinbase) for stablecoin payments
- Visa has extended support for Stripe’s MPP, which settles on the Tempo blockchain
- Mastercard just acquired BVNK for $1.8 billion to connect its fiat rails to stablecoins
- Stablecoin transfer volume reached $33 trillion in 2025 (+72% year-over-year)
The future of AI agent payments will be hybrid: cards for traditional commerce, stablecoins for micropayments and machine-to-machine transactions.
A $1 trillion market
According to Morgan Stanley, agentic commerce could generate up to $1 trillion in B2C revenue in the United States by 2030, with global projections of $3 to $5 trillion. Half of all online shoppers could be using AI agents by that date.
Jack Forestell, Visa’s chief product officer, describes agentic commerce as “the biggest opportunity in payments he has seen in over twenty years.”
The challenge remains trust: only 24% of American adults trust AI to make everyday purchases on their behalf. The first use cases are expected to remain “human in the loop” — the AI recommends, the human approves.
But the signal is clear: Visa, Mastercard, Stripe, and PayPal are investing heavily in an infrastructure where AI agents will be full-fledged economic actors.
📚 Glossary
- AI Agent: an artificial intelligence program capable of acting autonomously to accomplish tasks — here, making purchases and payments without human intervention at every step.
- MCP (Model Context Protocol): an open protocol that allows AI models to connect to external tools (here, the Visa payment network) in a standardized way.
- Stablecoin: a cryptocurrency whose value is pegged to a stable asset such as the dollar. USDC and USDT are the most widely used.
- Blockchain: a distributed and immutable ledger that records transactions without a central intermediary.
- Tokenization (payments): the replacement of the actual card number with a unique, limited-use code, reducing fraud risk.
Frequently Asked Questions
How does Visa CLI work for AI agents?
Visa CLI is a command-line tool that allows AI agents to make card payments from a terminal. Authentication is handled via GitHub OAuth, with no API key required. The agent can pay for services, data, or infrastructure on demand.
Which banks are participating in the Visa Agentic Ready program?
21 European banks are participating in the first phase: Barclays, HSBC UK, Revolut, Banco Santander, Commerzbank, DZ Bank, Nationwide, Raiffeisen Bank International, Nexi Group, Alpha Bank, and others. The program tests AI agent-initiated payments with tokenization and biometric authentication.
Can AI agents spend without limits?
No. The Visa Agentic Ready program relies on configurable limits: the bank and the consumer set spending caps. Each transaction requires a token linked to biometric authentication. The AI agent never sees the actual card number.
What is the connection between AI payments and crypto?
Visa CLI was created by Visa Crypto Labs and supports stablecoin payment protocols (x402, MPP). The future of AI agent payments will be hybrid: cards for traditional commerce, stablecoins for micropayments and machine-to-machine transactions.
When will AI agent payments become mainstream?
Visa predicts that millions of consumers will use AI agents for purchases by the 2026 holiday season. Morgan Stanley estimates that agentic commerce could represent $1 trillion in B2C revenue in the United States by 2030.
