Show HN: AgentPayy – Open-source payment framework for AI agents

Hey HN — I've been working on this and finally feel ready to share.

GitHub: https://github.com/AgentPayy/AgentPayy

AgentPayy is a payment framework designed for developers building AI agents and token-gated APIs. It's built for a future where agents interact economically — without needing human billing flows.

Right now, agents can't pay for services autonomously. Credit cards don't work. API keys are clunky. Most billing assumes a human is present. AgentPayy changes that.

It lets agents: – Generate wallets (gasless smart accounts) – Hold prepaid USDC balances or sign one-off payments – Pay APIs or tools directly on-chain using stablecoins – Process micro-payments economically (~$0.001 fees on Base L2)

Live now: – Smart contracts deployed on Base – TypeScript + Python SDKs published to npm/PyPI – Supports LangChain, CrewAI, and FastAPI integrations

Why I'm posting: This is v1.0.1 — not perfect, but functional. Stablecoins + L2s feel like the natural economic layer for autonomous software: programmable, low-cost, and composable.

Looking for feedback, use cases I've missed, and contributors (TypeScript, Python, Solidity). Contracts are public, and I'll be rewarding meaningful contributors over time.

Would love your thoughts.
