Rebooting the internet: inside the open-source project to let AI programs pay each other
The x402 Foundation, backed by major tech and financial firms, is developing an open-source protocol to enable seamless machine-to-machine payments over the internet. By reviving the dormant '402 payment required' HTTP status code, the initiative aims to facilitate micropayments for AI agents, potentially shifting the web away from an advertising-driven model.
Why it matters
This protocol could fundamentally alter the internet's economic structure by allowing AI agents to transact value directly, bypassing traditional subscription and ad-based revenue models.
Denelle Dixon, CEO of Stellar Development Foundation, one of the premier members of the x402 Foundation, helped engineer open-source browsers during the first iteration of the internet. She witnessed first hand when walled gardens were erected, and “five companies basically took over content on the web,” leading to the advertising-driven attention economy that exists today.
“You don't want to be in a walled garden when you're dealing with money,” Dixon said in an interview.
The x402 protocol is a payments standard for internet-based transacting, developed by cryptocurrency exchange Coinbase and now stewarded by its eponymous foundation. The goal is to enable payments between AI agents, machine and users through the standard internet language Hypertext Transfer Protocol (HTTP) without requiring subscriptions or manual entry of credit card details and the like.
