AI agents use x402 to make $24M in micro-payments

AI agents have begun using the x402 open crypto payment standard to purchase online services automatically. Over a recent 30-day span the rails recorded roughly 75 million payments totaling about $24 million, with an average payment of about $0.32.

Lincoln Murr, who leads AI product at Coinbase, recounted an example in which an agent collected Twitter articles, uploaded them to a file service and delivered the result by email without human intervention. The agent found and paid two tools-Firecrawl to scrape content and Stable Upload to host the file-using a wallet that Murr had not realized the agent held. Murr described the wallet as doing “double duty, serving as both the agent’s identifier and its payment method.”

x402 is designed to let software pay for access at the moment it is needed rather than relying on developer-created, pre-funded API keys. The Linux Foundation launched an x402 Foundation in April with founding participants that include Amazon Web Services, Stripe, Visa, Mastercard, American Express, Shopify, Google, Microsoft, Cloudflare and Coinbase. Coinbase contributed the original protocol and operates a discovery service, Bazaar, that indexes more than 10,000 paid tools agents can search and call directly.

Cloud providers have added features to support the flow. AWS added a capability in June that lets its content delivery service return machine-readable price and payment terms to bots requesting protected content and then verify payment at the network edge before giving access. Cloudflare introduced a similar feature in July and described the arrangement as ‘the agent becomes the buyer, and the request becomes the transaction.’ These features allow a requesting agent to receive price and terms and then be authenticated as having paid before content is released.

A population-scale settlement study published in July examined on-chain x402 activity and found a large share of transactions appeared to be internal or within linked wallet clusters. Researchers were able to verify $187,861 as payments to identifiable independent services. Another $20.07 million of the reported $24 million could be genuine external payments, but the study could not rule out connections between wallets behind some of those transfers.

Proponents say agentic payments let software shop for capabilities at runtime, comparing cost, quality and response time among vendors. That pattern replaces the common practice of developers creating accounts, generating API keys and pre-funding credits for each tool. Murr offered a use case in which an agent converting a PDF to a podcast might compare options on price and output quality and select the service that fits the task.

Coinbase is developing a product to let agents trade and pay directly from retail accounts. Murr expects trading agents and agentic data purchases to be an early test case because trading outcomes can be measured against the cost of data and services. He predicted agent-driven trading and data buying could gain traction within about six months.

The x402 ecosystem raises governance and discovery questions. If agents choose paid services, control over directories and ranking affects which vendors agents find. The foundation model is presented as a collective governance approach. Cloudflare and AWS continue to control access for sites behind their infrastructure, and the participants in the x402 Foundation aim to embed payment capability into standard internet infrastructure.

Industry participants are running further trials and building products to see whether small, targeted agent payments produce measurable returns and broader commercial activity.
