Coinbase has launched Agentic.market, the first marketplace where AI agents buy services on their own using stablecoin payments. The platform is built on the x402 protocol and offers thousands of services with no API keys or registrations required. Coinbase describes it as the "homepage of the agent economy."
An HTTP code that waited 30 years
HTTP status 402 Payment Required appeared in the 1990s as a reserved code for internet micropayments that never found a real use case. In May 2025, Coinbase took this dormant standard and built a payment protocol for AI agents around it. Now an agent can pay for a needed service mid-task, without any human input.
How Agentic.market works
Coinbase product lead Nick Prince framed the goal simply: "give humans and their agents access to thousands of services, with zero API keys required." The catalog already includes CoinGecko, Google Flights, social network X, and dozens of other partners.
People get a web interface to browse and compare services. Agents use a programmatic layer where the AI autonomously searches, filters, and connects new capabilities in real time. Each agent receives "skills" (ready-made code for interacting with a specific service) and a Coinbase Wallet for payments. Agents can both buy services and sell their own.
Who is behind x402 Foundation
Google, Microsoft, and AWS founded x402 Foundation in April 2026 to govern the protocol. The support coalition includes Visa, Mastercard, American Express, Stripe, Shopify, Cloudflare, Circle (issuer of USDC), Solana Foundation, and several others.
For a crypto protocol, this is an unusual crowd. Traditional payment networks and tech giants backing an open standard before mass adoption is rare. Historically, crypto initiatives like this stayed niche for years before getting names like Visa and Google attached.
How many agents are already paying
Coinbase reports hundreds of thousands of AI agents have already transacted hundreds of millions of dollars through x402. But before Agentic.market, agents found compatible services through "fragmented sources and word-of-mouth," as Prince put it. Now there is a single catalog.
Soon there will be more agents online than people
Coinbase CEO Brian Armstrong put it directly: "There will be more AI agents transacting online than humans very soon." Circle CEO Jeremy Allaire predicted in January 2026 that billions of agents would be transacting on blockchains daily within three to five years. Agentic.market is already live, the agents are already running, and the only open question is how fast volume scales from here.
