# Zuse

> Zuse is a maintained, board-verified index of licensed veterinary professionals and clinics, available over a REST API, an MCP server and Slack. It answers whether a person is licensed and in good standing (License check), who is licensed near a location (Nearby), which clinics are near a location (Nearby clinics), and what the public web says about a person or a clinic (Background, Intro notes, Clinic research).

License check and Nearby read from licensing boards of record; clinics also come from OpenStreetMap. Research is web-derived and is always labeled as such. Veterinary licensees in 27 states are live; GET /v2/coverage gives every state's standing.
