Solana Foundation has joined the new x402 initiative under the Linux Foundation, deepening its bet on payments for AI agents and internet services. The move puts Solana alongside big names like Amazon, American Express, Circle, Cloudflare, Coinbase, Fiserv, and Google in shaping an open standard for web-native payments.
What the x402 Foundation Does
The Linux Foundation launched the x402 Foundation to steward x402, an open payment protocol built around the HTTP 402 “Payment Required” status code. Coinbase originally developed x402 so APIs, apps, and AI agents can pay for access to data and services directly over the web without custom billing systems.
Under the new foundation, x402 will sit in a neutral, community-governed home. This structure keeps the core specification open and vendor agnostic. The goal is to let any company or developer use the same standard. They can charge per request, per call, or per session using digital payments. These payments will often rely on stablecoins.
Linux Foundation CEO Jim Zemlin says the x402 Foundation will help payments evolve in the same way as other internet protocols. He highlights goals such as transparency, interoperability, and broad participation. This framing positions x402 as a base layer for the emerging “agentic” economy. In that economy, software agents buy and sell services autonomously.
Why Solana Wanted a Seat at the Table
Solana has become one of the most active blockchains for x402 payments. It now handles about 65% of all x402 transactions this year, according to the Linux Foundation announcement. The network processes x402 payments with finality in around 400 milliseconds. Typical fees sit near 0.00025 dollars, which suits high-frequency machine payments.
The Solana Foundation has already promoted x402 as a key building block for AI agents and API monetization on its own website and in its ecosystem resources. It highlights use cases where AI agents pay for API calls, data, compute, or premium content in real time, using Solana as the settlement layer behind x402.
In its statement about joining the x402 Foundation, the Solana Foundation outlined clear goals. It said it wants to support “agentic payments” at internet scale. It also aims to help onboard more developers, merchants, and agents.
These users would adopt pay-per-request models powered by stablecoins. The group frames Solana as core financial infrastructure for the internet. It says the network already reaches billions of online users. Solana is now optimized for autonomous software payments.
The x402 ecosystem already includes partners like Cloudflare, Google, and Vercel, which are adding support so APIs and web services can charge via x402.
