Cloudflare Launches Monetization Gateway to Charge AI Agents via x402
Cloudflare unveiled the Monetization Gateway, a single control plane for its customers to charge for any asset behind Cloudflare — web pages, datasets, APIs, or MCP tools. At launch, payments settle in stablecoins over the x402 open protocol, which Cloudflare is building with Coinbase via the x402 Foundation, with verification and enforcement handled at the edge to shield origins from high payment volume. Buyers need no prior account with the seller because the payment itself is the credential, enabling sub-cent micropayments. Part of Cloudflare's 'Content Independence Day' push.
