API request format: https://weather.theonlinekenyan.com/api/forecast/TOWN eg for Nairobi: https://weather.theonlinekenyan.com/api/forecast/nairobi for Lodwar: https://weather.theonlinekenyan.com/api/forecast/lodwar for Rongai: https://weather.theonlinekenyan.com/api/forecast/rongai Note: No API request authentication is required The API responds with a JSON payload in the following format:
