Curator notes
Swagger/OpenAPI at /swagger/v1/swagger.json. Three operations: GET get_SiteDetails (monitoring stations with lat/long and region), GET get_ParameterDetails (pollutants and averaging periods), POST get_Observations (JSON body selecting sites, parameters and dates; hourly PM2.5, PM10, O3, NO2 and more). Returns plain JSON arrays; no pagination mechanism documented — keep date ranges small. Rate limits: unknown. Licence: unknown (not stated in the API docs).
