Google’s New AI Payment System: A Guide to AP2
The Agent Payments Protocol (AP2) is Google’s fresh take on secure, AI-powered sales, changing how AI handles money matters. As an open-source system, it tackles the big issue of how to approve payments when AI acts on its own, creating a standard for the coming age of AI sales. In this article, we will explain the impact of AI on Google Pay, аnd do you have to pay for Google AI.
What’s the Google AI Agent Payment System?
Google’s Agent Payments Protocol is an open standard developed with 60+ tech and payment companies to make secure transactions by AI agents easier.
Understanding AP2
Instead of old payment methods expecting a person to click buy, AP2 lets AI agents make purchases on their own, with proof users gave the okay. It builds on Google’s Agent2Agent (A2A) protocol and Model Context Protocol (MCP), creating a base for agent teamwork, now with payment options. AP2 is based on openness, user control/privacy, proof of intent, transaction accountability, and readiness for the future.
How Google AI Pay Is Different
Old payment systems assume a person starts each buy. AP2 changes this by using digital contracts called Mandates, which are signed to prove what the user wants. Mandates say what the AI can do, like spending limits, store rules, and time limits.
AP2 uses a two-step system: Intent Mandates set user rules, and Cart Mandates give the okay for buys. This means AI can only buy what users approve, with a record of each transaction.
How AI Changes Google Pay
AP2 is a game-changer because it fixes the trust problem when AI handles money. Old payment systems were made for people, but AI needs new ways to handle agent actions securely.
This changes how we check payments (using crypto proof instead of people), how we approve transactions (with digital mandates), and how payments happen (without people). It makes new business models possible where AI can negotiate, transact, and handle money on its own.
Why Google Made AP2 for AI Agents
Google saw three issues: assuming people are involved in buys, needing proof for AI-driven sales, and needing clear accountability when AI makes money choices. As AI handles shopping, subscriptions, and buying, not having payment standards caused problems.
Without a standard, the AI sales world would have mismatched solutions, causing security risks. By making AP2 open, Google wants to set rules for payments and help AI sales grow.
Working with Google Pay
AP2 works with Google Pay, not replacing it, adding security for AI payments. It works as a payment middleman, supporting credit cards, debit cards, bank transfers, and stablecoins.
This lets Google Pay users keep their payment methods but get better security from AP2. The open design works with other payment systems, avoiding lock-in and helping everyone adopt it.
Crypto and the Google AI Agent Payment Protocol
AP2 was created as a universal protocol that provides security and reliability for various types of payments, including transactions with stablecoins and other cryptocurrencies. The result of this work was the launch of a commercially ready solution for agent-to-agent cryptographic payments: the A2A x402 extensions.
Stablecoin and Crypto Features
AP2 shows Google’s strong move into crypto, supporting stablecoins and regular payments. It fixes the worry about crypto’s price changes by using stablecoins like USDC and USDT.
James Tromans of Google Cloud said AP2 was built considering both existing payment systems and new things like stablecoins. This lets AI switch between payments based on what users want or rules say.
Working with Coinbase for Crypto Payments
Google works with Coinbase to allow stablecoin use in AP2. Coinbase engineer Erik Reppel said the goal is to make payment systems work together: We’re all working to figure out how to make AI pay each other.
This partnership uses Coinbase’s storage and blockchain tech for secure stablecoin buys. It also links AP2 to Coinbase’s AI and crypto plans, like the x402 Bazaar program, combining their AI sales abilities.
Working with Ethereum
The Ethereum Foundation helps AP2 work with the decentralized finance world. They offer tech help with blockchain and smart contracts, letting AP2 use Ethereum for clear transactions.
The Ethereum Foundation noted the benefits, saying Ethereum makes AI more trustworthy, while AI makes Ethereum more useful. The more smart agents trade, the more a neutral base layer is needed to handle it. This suggests AP2 and Ethereum-based finance may work together more in the future.
Free vs Paid AI Payment Services
The free level includes Gemini Pro AI for questions, writing, and doc analysis, supporting text, voice, and pictures. AP2 features and advanced AI agent abilities likely cost money since they’re better than basic AI. The security and mandate systems suggest they’ll be in Google’s paid services.
Google AI Pro vs Ultra
Google AI Pro costs $19.99 a month, offering Gemini Advanced with longer talks, complex reasoning, and Google Workspace use. This includes 2TB of Google Drive and AI in Gmail, Docs, etc.
Google AI Ultra costs $249.99 a month, aimed at professionals needing top AI. This includes Gemini 2.5 Pro with better reasoning, early access to Project Mariner, and Veo 3 video creation. Ultra also includes YouTube Premium and 30TB of cloud storage.
Cost Analysis for Businesses and Individuals
For people, AI Pro is a good value at $20 a month, especially for Google users. The 2TB storage and Workspace AI can be worth it for productive users.
Businesses needing AI agent abilities and AP2 should expect higher costs, as it’s closer to the Ultra level. However, Google’s choice to include basic AI in Workspace plans (raising the price from $12 to $14 per user monthly) suggests they want to make AI accessible.
How Google AI Pay Works
AP2 uses credentials as signed digital contracts called Mandates. These show what a user allows, like spending limits, store rules, location, and time.
Mandates and Credentials
The mandate system uses a JSON structure with user ID, agent info, permissions, signatures, and timestamps. Each mandate is validated using ECDSA signatures, preventing changes. This turns user intent into verifiable proof.
Authorization
AP2 separates user and transaction permission. It needs two mandate types: Intent Mandates set user rules, and Cart Mandates approve buys. This stops unauthorized buys while letting agents work on their own within the rules.
Permission uses systems like Customer Authentication and TPM/HSM devices. It also has step-up methods like 3DS2 and biometric checks.
Security
AP2 uses encryption for data, multi-factor permission for mandates, and audit trails for tracking. It uses algorithms to find suspicious activity.
It fixes AI security worries like mandate spoofing and unauthorized transactions. It uses key storage, allowlists, and quantum-resistant crypto.
Google AI Agent Payment Protocol Benefits
Google AI Agent Payment Protocol has several important advantages. These include improved security, automated payments, and multiplatform.
