Cloudflare moved its Monetization Gateway into closed beta on 30 September. It lets a domain owner charge an AI agent for access to a website, an API, an MCP tool or a dataset using HTTP 402, the Payment Required status code that sat unused in the specification for three decades.
The design point is that it replaces authentication with payment. An agent that arrives without an account does not get a login page it cannot complete; it gets a price.
How a seller configures it
Sellers write rules that match elements of a request — the URL, headers, query parameters — and attach a price to each. Pricing can be fixed or variable, and where it varies the agent receives a maximum price quote before it pays, so a program can decide whether the request is worth making.
Settlement is in USDC on the Base blockchain, processed through Coinbase’s x402 facilitator. That is a deliberate choice rather than an incidental one: card networks are built around chargebacks and human account holders, neither of which fits a program making thousands of sub-cent purchases.
Who is already using it
Four products are charging through the gateway in production. Cloudflare’s own AI Gateway bills per inference. Ceramic.ai sells a web search API at a fixed price. Stocktwits sells market signals and sentiment data. API2PDF charges variable pricing for PDF generation.
The beta is limited to sellers and buyers based in the United States, with geographic expansion described only as coming soon.
Where it sits in Cloudflare’s stack
The gateway is one of three things Cloudflare now sells for the same problem. Pay Per Crawl charges when a crawler fetches a page. Pay Per Use, which also opened in beta on 30 September, charges an AI company when a publisher’s content appears in its product. The Monetization Gateway charges per request at the edge, in real time, with no relationship between the parties.
Each has a different party doing the counting, which is the thing to compare them on. Here the network does it, which is the strongest of the three positions for the seller.
What to watch
Whether buyers outside the United States get access before the agent-commerce standards now circulating settle on a different payment rail, and whether any large publisher prices its whole site this way rather than blocking agents.
