OpenGolfAPI — The Open Golf Course Database

About

OpenGolfAPI is a community-maintained database of US golf courses. Every course has a page with maps, scorecards, and contact info. Course owners can claim their page and update data directly. The entire dataset is open under ODbL — anyone can use it, build on it, or contribute to it.

Course Pages

Every course has a dedicated page with an interactive OpenStreetMap, scorecard, tee data, climate info, and nearby amenities.

REST API

Search, browse by state, get course details with tees, holes, climate, and nearby POIs. No API key needed.

MCP Server

AI agents can query golf course data directly. Works with Claude, ChatGPT, and any MCP-compatible client.

Bulk Download

Full dataset as GeoJSON, CSV, and NDJSON. Updated with each release. Use it however you want.

Community Edited

See wrong data? Fix it. Every course page has an edit button. Course owners can claim their page for direct updates.

ODbL Licensed

Same license as OpenStreetMap. Use it for anything — commercial, research, personal. Just attribute OpenGolfAPI.
