TL;DR:
- Coinbase and AWS integrated the x402 protocol into CloudFront and WAF, infrastructure that supports close to 25% of the internet.
- Publishers can activate AI agent traffic monetization without creating new accounts, invoices, or additional API keys.
- Payments are made in USDC on the Base network and onchain verification is handled by Coinbase’s x402 Facilitator within a single request cycle.
Coinbase and Amazon Web Services announced an integration that allows web publishers and API providers to monetize traffic generated by artificial intelligence agents through the x402 protocol. The solution runs on AWS CloudFront and Web Application Firewall, infrastructure the company estimates supports approximately a quarter of the internet, according to the official announcement.
Until now, most publishers either blocked AI agent traffic or granted access to their content without any economic compensation. The new integration aims to turn those agents into a formal category of paying customers. When an agent requests content, the server returns an HTTP 402 “Payment Required” response that specifies the amount and payment method. The agent pays in USDC on the Base network, Coinbase’s x402 Facilitator verifies the payment onchain and the content is delivered, all within a single request cycle.
Coinbase: An Open Protocol for Agentic Commerce
The system requires no new accounts, invoices, or API keys. Publishers can enable the feature from their current AWS configuration. The protocol supports billing per individual request, batch settlement for high-frequency micropayments, subscription models and variable pricing based on usage, providing flexibility for different types of workloads, including high-compute API calls.
“Before a single byte is served, we can answer three questions: who is this agent, what is their intent, and are they authorized to pay,” said Nishit Sawhney, general manager of AWS Edge Services. For his part, Brian Foster, head of infrastructure growth at Coinbase, noted that x402’s goal was always to give the internet a native payment layer for agents.
Coinbase incubated the protocol and then transferred its governance to the x402 Foundation, under the Linux Foundation. AWS is among more than 20 founding members. Enabled publishers can list their endpoints on the x402 Bazaar, an open registry of compatible services, or on Agentic.Market, the curated catalog operated by Coinbase.
