What Are Agentic Payments?

What Are Agentic Payments?

Agentic payments are transactions initiated or conducted by an autonomous artificial intelligence (AI) system.

In a typical online purchase, a human is involved at every step: selecting a product, entering card details, and confirming the purchase. The new model eliminates the last step—the digital assistant makes decisions, authorizes, and completes the transaction, often without the buyer's involvement.

An AI agent is an autonomous program that independently determines and executes actions to achieve a goal, such as processing a payment on behalf of a user.

These operations have varying degrees of autonomy:

In passive mode, the system flags a bill for payment and waits for human confirmation. In intermediate mode, it acts independently but escalates large transactions for manual review.

In fully autonomous mode, the assistant tracks expenses, compares available options in real-time, and pays according to predefined rules.

The key distinction between agentic payments and traditional automation lies not in the absence of human involvement but in the system's ability to choose actions independently in a changing context.

The difference between an agentic operation and a standard automatic payment is in the logic of initiation. An automatic payment follows a simple rule, such as deducting an amount on a specific date. An AI agent, however, assesses the situation, compares options, and decides on a transaction based on set constraints.

Questions of liability and fraud risk remain unresolved at the industry level: regulators have not clarified who is responsible if the system exceeds its authority or misinterprets instructions. Therefore, most services leave large transactions for human review.

How Do Agentic Payments Work?

The mechanics vary from service to service, but most follow a common principle.

The user sets parameters in advance: budget ceiling, list of approved vendors or categories, and level of autonomy. These settings act as standing instructions. When the assistant identifies a condition for making a payment—such as renewing a subscription, restocking supplies, or purchasing a flight ticket based on specified preferences—the AI checks the options against these rules.

Next, payment is made using an approved method. In traditional finance, this could be a digital wallet or a secure connection to a card. In blockchain, the assistant uses its own wallet and sends funds directly over the network.

The main difference lies in the approval mechanism. A standard payment confirms the user's right to execute a transaction through a payment instrument. An agentic payment checks whether the AI agent has permission to act on behalf of the user and whether the specified constraints are met.

Mastercard issues a special digital token to the assistant with embedded conditions—how much can be deducted and to whom to transfer. Visa's Intelligent Commerce platform relies on a similar principle: its Trusted Agent Protocol verifies the agent's authenticity and authority before executing a transaction.

Who Is Behind Agentic Payments?

The infrastructure is being built by three main groups: payment networks, technology platforms, and crypto projects.

Payment Networks

Visa launched its Intelligent Commerce platform in 2025, following five years of investments in technology and security—over $13 billion.

By December, the company reported hundreds of transactions conducted by autonomous systems in a live environment without human involvement at the payment stage. It developed the Trusted Agent Protocol in collaboration with Cloudflare, Microsoft, Shopify, Stripe, Adyen, Coinbase, and Worldpay.

Mastercard introduced Agent Pay in April 2025 and claims to have conducted the first such operation based on digital tokenization. The coordination of business processes is managed by IBM's watsonx Orchestrate platform.

Technology Platforms

PayPal has focused on developers, releasing a toolkit that grants assistants access to the platform via API.

In November 2025, in partnership with Perplexity, it launched Instant Buy—ordering directly in chat with over 6000 vendors. Payment within ChatGPT was integrated through the Agentic Commerce Protocol from OpenAI.

Shopify, in collaboration with Google, developed the Universal Commerce Protocol—an open standard that describes how AI agents place orders with any vendor, from catalog to payment. The company connected its stores to AI chats through Agentic Storefronts, introduced in December 2025: sellers set up their storefronts once, and their catalogs automatically integrate into ChatGPT, Perplexity, and Microsoft Copilot.

Google released the Agent Payments Protocol—another open standard joined by Mastercard, PayPal, American Express, Coinbase, Salesforce, Shopify, Cloudflare, and Etsy.

Infrastructure

Major companies are actively working on the technical foundation and allocating significant resources for its development:

• In May 2025, Coinbase launched x402—a protocol for direct service payments via HTTP using stablecoins;
• Stripe showcased its own solution based on USDC and the same protocol;
• Alchemy introduced the AgentPay gateway, which consolidates payments from different systems into one point, and, together with Visa, launched a separate service;
• Coinbase and Stripe are assisting Amazon in enabling payments for AI assistants.

What Barriers Does Blockchain Face?

Structurally, autonomous systems and blockchain complement each other. Traditional financial services are designed for humans: you need to create an account, enter a password, and wait for the bank to process a batch of transactions.

A digital assistant has no credit history, does not fill out forms, and is not tied to a subscription model. It needs to pay only for what it consumes, and immediately—without banks or processing.

This is where blockchain comes in. A wallet with stablecoins can send funds anywhere at any time—for mere cents. There’s no need to open an account or wait for approvals, and the transaction completes in seconds.

However, on-chain payments face barriers to widespread adoption. Many vendors are cautious about digital assets and do not accept them. The regulatory status of stablecoin payments varies by country, and in many jurisdictions, it remains undefined.

For everyday purchases, card networks maintain an advantage that blockchain currently lacks: fraud protection and a mechanism for disputing transactions.

A likely scenario is the coexistence of both systems.

What Role Does x402 Play?

x402 is a payment standard based on a long-reserved but previously unused internet code.

The "402 Payment Required" status in the HTTP protocol was intended for paid access to content but was not practically applied. In May 2025, Coinbase and Cloudflare activated it, turning it into a working payment mechanism for autonomous systems.

When a user, application, or AI requests paid digital content, the server instantly returns the exact price and wallet address. The buyer's system automatically sends the funds. Once the background service confirms the transaction on the network, the data becomes available.

The entire process takes mere seconds, eliminating the need for subscriptions, API keys, and manual invoicing.

The standard was initially built around USDC on the Base network, but it is not tied to a specific blockchain or token and supports payments in Polygon, Arbitrum, Solana, and other networks. Fees are mere cents, allowing the assistant to pay for tiny amounts of data or seconds of computation. Such sums are unjustifiable for card networks.

Since its launch on Solana, over 35 million transactions have been processed via x402, with a turnover exceeding $10 million. In April 2026, the team introduced Agentic.Market—a marketplace where people and autonomous assistants find, compare, and connect compatible services without API keys.

Can Agentic Payments Be Tracked?

The answer depends on whether the transaction occurs on-chain or through traditional financial networks.

On-chain transactions are public by default. Any transaction on Base, Solana, or Ethereum remains permanently in an open ledger. The wallets of the sender and receiver, the amount, and the time are publicly visible. The only hidden aspect is who stands behind a specific address.

This linkage is restored by on-chain analytics platforms, such as Arkham or Chainalysis. They analyze transaction patterns, counterparty relationships, and wallet behavior across different networks, then match addresses with real participants—exchanges, funds, protocols, and individuals. If the assistant interacts with a pre-tagged wallet, its activity is visible in real-time.

In the case of x402, each micropayment is recorded at the settlement level and is traceable in principle. An analyst with access to such tools can see the assistant's wallet, understand what services it is paying for, and reconstruct its operational profile. The protocol's settlement layer generates data that functions as a verifiable audit log.

With off-chain operations, the situation is reversed. When a payment is made through Mastercard Agent Pay or Visa Intelligent Commerce, it goes through traditional payment networks. This data is stored in closed databases and is accessible only to the issuer, acquirer, and the payer's servicing bank. It is hidden from the public, and on-chain analytics tools cannot see it.

As the number of AI agent wallets grows, this difference in transparency will become more apparent to both regulators and the market.
