AgentPay SDK launches
An open‑source AgentPay SDK appeared that handles USD‑pegged stablecoin flows with policy rules, approvals, and self‑custody primitives—bringing programmable payments into agent ecosystems. The SDK frames monetary flows as first‑class agent actions with embedded policy checks. (x.com)
World Liberty Financial (WLFI) published the AgentPay SDK as an open-source toolkit tied to its USD1 stablecoin in a March 2026 release, positioning USD1 as the default settlement asset for the SDK. (kucoin.com) The SDK runs as a local daemon with an agentpay CLI that manages wallets, balances, transfers and policy enforcement, and the project documentation explicitly describes a machine-side installation path and CLI/daemon workflow. (github.com) AgentPay enforces token-first, terminal-based policy controls including spending limits, overrides and manual approval overlays while exposing native transfers, ERC‑20 approvals, raw broadcast flows and local manual approval handling. (github.com) The codebase and launch materials emphasize self‑custody signing boundaries using Secure Enclave / TEE-style local signing so private keys “stay on your machine,” according to the project site and SDK docs. (agentpay.worldlibertyfinancial.com) Out-of-the-box chain support includes EVM-compatible networks such as Ethereum mainnet and BNB Smart Chain with USD1 preconfigured as the primary asset, and the releases note Bitrefill as an example plugin integration. (stablecoininsider.org) The project publishes a plugin system and “skill pack” integrations for popular AI hosts (examples called out in coverage include Claude and other agent hosts), aiming to let agents request payments via host plugins rather than bespoke code per integration. (stablecoininsider.org) The GitHub repository metadata shows the project in early active development (single main branch with three commits, five forks and seven stars at the time of the launch announcement), and public release notes list roadmap items like meta‑transactions and broader cross‑chain routing. (github.com) Coverage and technical docs call out explicit error management and recoverable workflow patterns for automated payment failures, and the SDK’s API-first design exposes HTTP hooks for 402/payment-required flows that can be instrumented by platform observability tooling.
