# ALTER — Identity Infrastructure for AI Agent Commerce > ALTER is the human identity layer for the AI economy. > ERC-8004 proves your agent is real. ALTER proves the human behind it is qualified. > Users own their psychometric identity. ALTER earns by being the best implementation of an open standard. ## What ALTER Does ALTER maps human identity through psychometric assessment, then monetises that identity through the x402 micropayment protocol. When companies or AI agents query a person's identity profile, the data subject earns 75% of the transaction fee. ## MCP Server ALTER exposes an MCP (Model Context Protocol) server for AI agent integration.
