The A2A x402 Extension brings cryptocurrency payments to the Agent-to-Agent (A2A) protocol, enabling agents to monetize their services through on-chain payments. This extension revives the spirit of HTTP 402 "Payment Required" for the decentralized agent ecosystem.
Payments are broken for AI agents. Snaplii provides a secure, tokenized payment layer that enables AI agents to transact in the real world — without exposing users' underlying payment credentials.
Give any AI agent a crypto wallet. Agents deserve access to money. Pay x402 APIs, receive USDC, check balances — autonomously. Works with Claude, LangChain, AutoGen, CrewAI, and any MCP client. EVM + Solana.
