# Aidenix > Aidenix does two things for AI agents and B2B teams. It maps where authoritative > real-world data lives and how to fetch it — nearly 4,000 public sources with > runnable recipes, exposed over MCP and REST. And it turns that into outbound: > scoring lead lists 0-100 against your ideal customer profile, enriching from > public sources, and drafting a personalized first-touch email per contact. > Data comes from public sources only. Every endpoint we document is live-probed, > and failures are published rather than hidden. ## Open data guides Practical guides to free and open company-data APIs.
