CIMIS Web API
URL: http://et.water.ca.gov/Rest/Index
Users need an application key (AppKey) in order to have access to CIMIS Data using the Web API. An APPKey is generated after creating an account with CIMIS (using CIMIS website at https://cimis.water.ca.gov/). After generating the APPKey, users have access to the REST Services, which provides hourly and daily data. Examples of Web API inquires can be found by clicking "Online Service Tests" under http://et.water.ca.gov/Rest/Index.
