AgentKey is a data marketplace and connectivity layer that lets AI agents access dozens of external data sources through a single API key and one MCP installation. It supports agents such as Claude Code, Cursor, Windsurf, Gemini CLI, and Codex, removing the need to manage individual API keys and billing for each service. Supported data categories include web search, web scraping, social media platforms, financial market data, on-chain crypto data, and e-commerce feeds. AgentKey handles failover automatically when a provider goes down, ensuring continuous data access. It is designed specifically for AI agent workflows that require real-time, live external data to complete research and analysis tasks.
