WLFI Launches AgentPay SDK, USD1 Becomes the Economic Operating Layer Designed for Autonomous AI Systems

BlockBeats News, March 20, according to official sources, World Liberty Financial (WLFI) has officially launched the AgentPay SDK—an open-source, self-hosted payment infrastructure tailored for the AI Agent economy, built around the USD1 stablecoin. Key highlights include: · AI Agents can self-host, transfer, and use USD1 for payments on EVM-compatible chains · Fully self-hosted: Private keys remain on the operator's local machine, with zero data access by WLFI · Strategy engine first: Every transaction must pass user-defined strategy checks, with no bypass allowed · Manual approval mechanism: Transactions exceeding thresholds are automatically paused, awaiting manual confirmation (end-to-end encryption) · Supports mainstream AI tools and Agents: Claude Code, Codex, Cursor, Windsurf, Cline, Goose, OpenClaw, etc. · Built-in Bitrefill plugin: Agents can directly purchase gift cards, eSIMs, prepaid cards, and more · Fully open-source (MIT License), zero platform fees According to the official statement, the birth of the AgentPay SDK signifies that USD1 is no longer just a traditional stablecoin but has evolved into an economic operating layer specifically designed for autonomous AI systems. The AgentPay SDK is defining the default payment paradigm for AI agent economies, enabling Agents to perform financial operations at "machine speed" under controlled and secure conditions.
