According to the article by CoinDesk's Ian Allison, the new AgentPay solution aims to support multiple payment protocols, including x402, which was incubated by Coinbase and now maintained by the Linux Foundation, as well as Machine Payments Protocol (MPP), which was launched by Stripe and is supported by Visa. "A merchant registers their existing API with us, we give them a new endpoint, and any agent on any supported protocol can pay them through it," Alchemy CTO Guillaume Poncin told Allison in an email.
