XMR402 is an open, neutral standard for internet-native payments. It absolves the Internet's original sin by natively making payments possible between clients and servers, creating win-win economies that empower agentic payments at scale. XMR402 exists to build a more free and fair internet.
xmr402-org is an early-stage TypeScript project in the AI payments / x402 ecosystem, focused on ai-agents, ai-tools, http-402, m2m. It currently has 10 GitHub stars and 5 forks, and sits alongside related tools like ripley-guard-ts, dna-x402, docs.
XMR402 is an open, stateless, and decentralized HTTP payment standard built for the Monero ecosystem. It allows AI Agents and browser-based users to bypass service gates via millisecond-level 0-conf transaction proofs (TX Proof).
