Banks Warn AI Shopping Agents Outpace Fraud Protections

Expedia announced a partnership with Meta's personal AI agent Muse that will let travelers plan and book trips, hotels, and flights directly through the agent. In a post on X, Expedia said, "We're joining with Muse: tell it where you're headed, and it can work with Expedia to sort your hotels and everything in between." The online travel agent did not specify when Muse will be available for use on the Expedia platform. Muse is also partnering with PayPal, allowing customers to shop and book travel through the Muse agent. The announcement helped bolster Expedia shares, which had been beaten down earlier in the session as investors weighed the potential threat posed by the Muse app, which topped Apple's App Store download rankings; Expedia, Booking Holdings, and Airbnb all came under pressure Tuesday as investors assessed the potential impact of Muse's ability to bypass traditional OTAs.

GreenCore Solutions Corp. has opened A2A-Peptides.ai, an Agent-to-Agent hub for the licensed peptide trade served over the Model Context Protocol at mcp.a2a-peptides.ai. The service is business to business and is built for parties that already hold a licence to manufacture, wholesale, dispense or prescribe in a listed jurisdiction, with product-level information available only after a jurisdiction and licence gate; GSC is not the seller of record and licensed counterparties fulfil. The hub runs on nine rule sets covering the United States, Canada, Mexico, the European Union, the UK, South Korea, Japan, Singapore and Switzerland, spanning 35 countries, with compute on Microsoft Azure in the United States. At launch it carries 5,301 presentations on a Brand–Strength–Form–Route–Device–Pack matrix and 24,694 provider records read from licence registers, and it answers AI agents from Anthropic, OpenAI, Google, Perplexity, xAI and Mistral. GSC offers fixed-fee tools for licensed businesses on a monthly or annual basis, including answer-engine optimization, listings, an answer agent and an AI agent with a gated handoff of a quote or request to the licensed counterparty. The company also operates A2A-Cosmetics.ai, its agentic commerce hub for cosmetics, live on Microsoft Azure in 18 markets with 19,031 products, 22,738 suppliers, 6,882 retailers and 1,547,024 retail points of sale.
