This pulls Korea's official public restroom dataset and optionally augments it with Kakao Local API results to find nearby bathrooms. It always asks for your location first instead of guessing, then uses Kakao Map anchor resolution to pin coordinates and query the nationwide CSV by region when possible. All distances are recalculated with haversine to stay accurate, and duplicates within 50 meters get merged. Responses are short, usually three to five options with name, distance, address, and map links. It won't tell you real-time occupancy since the standard data doesn't track that, but it's solid for "where's the nearest public restroom from Gwanghwamun" type queries in Korean contexts.
