  • x402
    x402 is the open payment protocol that activates the dormant HTTP 402 status code, enabling instant, machine-native settlement for digital resources.
    This is the internet’s native payment layer: x402 revives the HTTP 402 “Payment Required” status code, transforming the standard request-response cycle into a direct, pay-per-use transaction. The protocol allows a server to respond with a 402 status, detailing payment requirements (e.g., USDC on Base), which an AI agent or client wallet fulfills instantly. This system eliminates traditional friction like accounts and subscriptions, providing permissionless, near-zero-fee settlement, often in under two seconds. It is critical infrastructure for the emerging agentic economy, allowing autonomous AI agents to discover and pay for API access and data without human intervention.
  • USDC
    USDC is a fully-reserved, regulated stablecoin: a digital dollar issued by Circle, pegged 1:1 to the US dollar, enabling 24/7 global liquidity.
    USDC (USD Coin) is a key financial technology: a digital dollar stablecoin issued by Circle and backed 1:1 by highly liquid cash and cash-equivalent assets. This regulated digital currency is designed for stability, providing a reliable on-ramp to the crypto economy while maintaining the value of the US dollar. Its architecture, built on open protocols and natively available across over 30 blockchain networks (including Ethereum, Solana, and Polygon), facilitates near-instant, low-cost, and accessible global payments and trading. Circle ensures transparency with monthly reserve attestations published by a Big Four accounting firm, cementing USDC's role as a trusted, institutional-grade instrument for digital finance.
