AgentPay SDK

open source

Payments for agents, in whatever language you ship.

What it does

AgentPay gives coding agents and automated systems a disciplined way to initiate and confirm payments. The SDKs wrap one OpenAPI contract, so behavior stays identical no matter which ecosystem your stack lives in.

Every SDK ships only when it is real: HMAC signing, idempotent requests, typed decision errors, a health-check integration test, and a release workflow. No placeholder packages.
