AiFinPay is the x402 payment rail for autonomous AI agents — live on
Polygon and Solana mainnet. Non-custodial. One line of code pays any
gated URL on-chain and returns the response.

This is the SDK home — Python + Node SDKs, the @aifinpay/mcp MCP
server, framework adapters (OpenAI Agents / LangChain / CrewAI /
Flowise / AutoGPT), and live partner bridges.

Get started

pip install aifinpay-agent --pre
npm install @aifinpay/agent@alpha
npx @aifinpay/mcp
