   Sierra and Stripe let AI phone agents take card payments mid-call

   Sierra, the AI customer service startup led by Bret Taylor, announced a partnership with Stripe that lets its voice agents take card payments during a phone call, according to The Next Web and a Sierra blog post. When it is time to pay, the agent switches into a secure mode and the caller types card details on the keypad, which are routed to Stripe; the agent then confirms the transaction and continues the call. Sierra says the agent never sees card details, only payment status and the last four digits. Healthcare billing firm Cedar was an early user, and Sierra says 71.3% of calls in which patients start a payment with Cedar's agent Kora end in a successful payment — a vendor figure also repeated by The Next Web. Sierra is now listed in the Stripe App Marketplace, and the companies are also working on the Personal Agent Protocol open standard that Sierra and Meta announced, including how agents pay on someone's behalf.

   Meta, Sierra and partners launch Personal Agent Protocol for AI agent commerce

   Enterprise AI startup Sierra said on Oct. 6 that it is developing the Personal Agent Protocol (PAP) with Meta and companies including Walmart, Shopify and Stripe — an open standard governing how user-authorized personal AI agents access businesses' websites, APIs and services. Sierra co-founder Bret Taylor said the protocol is designed to handle authentication, empower consumers and give companies visibility into what personal agents do through their sites, APIs or company agents, and that it is open for anyone to implement; Meta's David Singleton compared it to email as a universal standard. The move follows Amazon blocking Meta's Muse agent from its retail site and reports of agents hitting anti-bot blocks on other retail sites, where users often cannot tell whether a block is intentional or accidental.
