Trust, transactions and tokenomics: AI agent infrastructure begins to standardize
The New Stack Paul Sawers
Coinbase's x402 payment protocol for AI agents just got its own neutral home at the Linux Foundation, backed by 40 companies including Google, AWS, Visa and Mastercard.

Something quietly important happened this week for anyone building AI agents that need to buy things online. The Linux Foundation formally launched the X402 Foundation, taking over governance of a payment protocol that lets software pay software — no human account setup, no API key management, just an HTTP request, a payment-required response, and a stablecoin settlement that happens in seconds.
The protocol itself isn't new. Coinbase built x402 back in May 2025, then partnered with Cloudflare that September to spin up independent governance before eventually donating the whole thing to the Linux Foundation this past April. Now it has 40 members on the roster, and the list reads like a payments and cloud who's-who: AWS, American Express, Mastercard, Stripe, Shopify, Visa, plus Google and Cloudflare. AWS and Coinbase already let any site on AWS charge agents per request, and Cloudflare rolled out a similar tool weeks later for datasets, APIs, and AI tools.
Mike Dolan, who runs projects and legal at the Linux Foundation, frames this as part of a bigger pattern. Alongside x402, the Foundation has also stood up the Tokenomics Foundation for standardizing token-cost measurement — a real problem given that average monthly token spend reportedly jumped 13-fold in the year to April 2026 — and the Appia Foundation for verifying AI safety and compliance claims that currently rest on nothing but a vendor's word. Dolan's pitch is that agents can't operate at scale without neutral, shared infrastructure across cost, compliance, and payments, because no company will build on rails controlled by a rival.
One gap stands out: Anthropic and OpenAI aren't on the x402 member list, even though both sit on the Agentic AI Foundation that launched last year. Dolan says the two efforts are coordinating on commerce standards and that the door is open, but it's a notable absence given how central those two labs are to actual agent deployment.
The traction numbers, self-reported by x402's own tracker, claim more than 75 million transactions worth $24.24 million over the past 30 days, spread across roughly 94,000 buyers and 22,000 sellers. That's real activity, even if the figures come with an obvious asterisk since nobody's verifying the breakdown by use case. Whether this becomes the actual settlement layer for the agentic economy, or just one of several competing standards, probably depends on whether Anthropic and OpenAI eventually show up.
My take — AI-written commentary, not fact-checked reporting
Every time a payments consortium rolls in Visa, Mastercard, and Stripe together, my instinct is to check who's missing rather than who's there — and Anthropic and OpenAI sitting out the payment rails for their own agents is the tell here. Neutral governance sounds great until you realize the biggest model builders haven't committed to the plumbing yet, which makes this look less like an industry consensus and more like the card networks and cloud giants racing to lock in the standard before the labs even show up to negotiate.
