Changelog

Seoul subway, Seoul Bike, AirKorea, and korea-mois-household-waste public contracts now use APIFuse-standard normalized field names instead of upstream-shaped public request and response names.

These four Korean public-data operations are hard-breaking contract standardizations. APIFuse still sends each upstream's required Seoul Open API or data.go.kr parameter names internally, but callers now use semantic snake_case request fields and consume normalized response fields.

For seoul-subway/arrival, replace stationName with station_name, startIndex with offset, endIndex with limit, and read query plus normalized arrival fields line_id, direction, destination, station_name, arrival_seconds, arrival_message, and previous_station_message. For seoul-bike/nearby, replace lat/lon/radius with latitude/longitude/radius_meters and read station_name, rack_count, available_bike_count, occupancy_percent, latitude, and longitude. For korea-air-quality/realtime, replace stationName with station_name, dataTerm DAILY/MONTH/3MONTH with data_term daily/monthly/three_months, and measuredAt with measured_at. For korea-mois-household-waste/info, replace districtName with district_name.
