aaaa-nexus — Formally Verified AI Safety APIs

aaaa-nexus is an MCP (Model Context Protocol) server that provides a suite of formally verified AI safety and DeFi APIs designed for autonomous agents, AI assistants, and AI-driven applications. It exposes over 200 API endpoints across more than 20 safety and security product families, including certifiable random number generation, hallucination detection, provable trust scores, agent authentication, post-quantum session security, transaction escrow, compliance checks (EU AI Act, NIST, ISO), on-chain reputation, key management, and more. It supports agent-to-agent payments via USDC (x402 protocol) and requires no sign-up for free or trial use. Its robust integration with Claude, Cursor, Windsurf, LangChain, CrewAI, and any MCP/A2A-compatible clients makes it a universal safety toolkit for agent frameworks, research labs, developers, and organizations seeking verifiable safety, trust, and compliance infrastructure for AI deployments.
