Amazon Web Services has launched a preview of Bedrock AgentCore Payments, allowing AI agents to access and pay for APIs, MCP servers, web content and other agents during execution.
AWS introduced the service with Coinbase and Stripe, describing it as the first managed payment capability built for autonomous agents, covering wallet authentication, transaction execution, spending controls and observability.
The preview connects agents to either a Coinbase CDP wallet or a Stripe Privy wallet. Developers can set session-level spending limits before the agent runs, and AWS says those limits are enforced at the infrastructure layer.
When an agent reaches a paid resource and receives an HTTP 402 “Payment Required” response, AgentCore handles x402 negotiation, wallet authentication, stablecoin payment and proof delivery without interrupting the agent’s execution loop.
AWS documentation says teams building agent payments themselves must manage separate billing relationships, third-party wallets, orchestration logic, edge cases, budget controls and end-to-end observability.
AgentCore Payments moves those functions into a managed service and exposes payment activity through logs, metrics and traces in AgentCore observability.
Standardizing machine-to-machine transactions
The payment flow is built around x402, the HTTP-native protocol developed by Coinbase for machine payments. Coinbase says its x402 layer and wallet infrastructure are now integrated into AgentCore Payments, allowing agents to discover services, make USDC micropayments and use paid resources with budget controls and audit trails. Coinbase also says settlement happens in about 200 milliseconds on Base with USDC.
AWS is also making the Coinbase x402 Bazaar MCP server available through AgentCore Gateway, saying it provides more than 10,000 x402 endpoints that agents can search, discover and pay for autonomously.
Stripe’s role runs through Privy, the wallet infrastructure company it acquired in 2025. Stripe said Privy is providing wallet infrastructure and payment rails for the first AgentCore Payments capabilities alongside Coinbase.
Stripe has also launched its own Machine Payments Protocol with Tempo, an open standard for agents and services to coordinate programmatic payments including microtransactions and recurring payments.
A fragmented landscape of protocols
AWS is starting with x402, but agent payments are not settling around one technical approach. Google’s Agent Payments Protocol uses cryptographically signed “Mandates” as proof of user instructions, aiming to answer authorization, authenticity and accountability questions when agents transact for users. Visa’s Trusted Agent Protocol focuses on merchant trust, giving sellers a way to verify approved agents and separate legitimate agent traffic from bots.
The x402 protocol is also moving into a more formal open-source structure. In April, the Linux Foundation announced the launch of the x402 Foundation, with support from companies including AWS, Coinbase, Stripe, Google, Microsoft, Visa, Mastercard, Shopify and Cloudflare. The foundation said x402 will remain vendor-neutral under Linux Foundation governance.
Regulatory and liability hurdles
For enterprise finance teams, the harder question is whether each agent payment carries clear authorization, accountability and audit evidence after the transaction.
The IMF made the same distinction in an April note on agentic AI in payments, warning that payment systems rely on deterministic rules while agentic AI systems use probabilistic decision-making.
The note highlighted risks around authorization traceability, opacity, correlated agent behavior, cybersecurity and unresolved legal liability.
U.S. money-transmission rules may add another layer of caution. Federal regulations define money transmission services as accepting currency, funds or other value that substitutes for currency from one person and transmitting it to another person or location by any means.
The same section includes exclusions for some network access providers and payment processors, making the facts of a specific payment design important.
The trillion-dollar commerce opportunity
McKinsey estimates that agentic commerce could orchestrate up to $1 trillion in U.S. B2C retail revenue by 2030, with global projections reaching $3 trillion to $5 trillion – for commerce activity influenced or executed by agents, not for the payment infrastructure itself.
AgentCore Payments is available in preview in US East (N. Virginia), US West (Oregon), Europe (Frankfurt) and Asia Pacific (Sydney). AWS has not disclosed a general availability timeline.
