PayPal Enterprise Payments, formerly Braintree, provides tokenization and payment processing for transactions initiated by AI agents. Merchants receive constrained payment tokens and continue using standard charging, settlement, refund, chargeback, risk, and compliance workflows; the tokens can be limited by merchant, amount, currency, and expiry so card details remain outside the agent and the merchant's PCI scope. The service supports agentic-commerce integrations including Instant Checkout in ChatGPT through the Agentic Commerce Protocol, Google AI Mode through the Universal Commerce Protocol and Google Pay, and MCP apps that either provide an in-agent checkout interface or hand off to an external checkout page.

PayPal's agentic commerce services help merchants create AI-powered shopping experiences in which customers use everyday language to discover products, manage carts, and complete purchases across online stores and AI platforms. The services include Agent Ready, which lets merchants accept payments through AI assistants using existing PayPal tools, and Store Sync, which connects product catalogs and cart operations to AI shopping assistants and existing order-management systems. PayPal also describes catalog enrichment as a way to make merchant product data more suitable for agent discovery and recommendations; its experiments found that targeted enrichment helped, while unstructured boilerplate could dilute the signal and increase hallucinations. Merchants can connect product listings through PayPal partners and use one integration to reach multiple AI shopping platforms. Access requires submitting a form to PayPal's AI team, which then guides onboarding.

Buy for Me is Amazon's AI shopping agent. When a requested item is unavailable on Amazon, it visits another brand's website, selects the product, and fills in the customer's name, address, and payment information to complete checkout. It is presented as part of the shift toward AI-assisted product discovery and purchasing outside Amazon's own marketplace.

Commerce Agents is Anthropic's reference implementation for building shopping agents for customers and merchant agents for back-office staff with Claude. It defines each agent through prompts, skills, tool contracts, grounding, memory, approval gates, and backend interfaces, and provides runnable examples for retail, travel, telecom, and entertainment. The shopping agent searches and compares products, plans purchases, fills carts, answers order and policy questions, and maintains customer memory. The merchant agent analyzes performance, manages listings and inventory alerts, handles pricing and promotions, and drafts campaigns; its writes are staged until a host approves them. The agents can run through the Anthropic Messages API, Claude Agent SDK, or Managed Agents, and the repository provides a Claude Code plugin for scaffolding or reviewing commerce agents.
