What you get

One key you hold — bound to your OpenGolf ID. It powers all your apps; you control it.
Free to read — every US + international course, scorecards, tees, geometry. No key needed for reads or gross scoring.
Contribute + identity — the key lets your app write moments/shots and sign your users in with their own OpenGolf ID.
MCP + REST — same platform for your code and your AI agents: npx @opengolfapi/mcp-server or the REST API.
Your users' identity stays theirs — apps get identity only; a user's key/record is never yours to mint.
