The x402 Foundation, operating under the Linux Foundation, has launched a new protocol that enables AI agents to make payments for services using HTTP 402 'Payment Required' status codes. This system, which utilizes USDC on the Base blockchain, allows agents to pay for resources like API calls and content access on a per-request basis, with average transactions around 32 cents. While this addresses one-way payments, it does not solve the problem of two-way value exchange between agents, which still requires solutions like hash-time-locked contracts (HTLCs) for atomic, cross-chain trades.

IMPACT Enables AI agents to autonomously pay for services, potentially accelerating the development and deployment of agent-based applications.
