WHENWhen building DataQuery with start parameter of type datetime

ACTIONverify end parameter is also of type datetime

CONSEQUENCEMixed datetime and date types for start/end cause query construction to fail with ValueError, resulting in invalid API requests that return no data or incorrect data

WHENWhen handling HTTP responses from data API

ACTIONvalidate status code is 2xx before processing response

CONSEQUENCEProcessing non-2xx responses as valid data causes silent failures where error messages are treated as actual data, corrupting downstream analysis

WHENWhen constructing DataQuery with start and end dates

ACTIONmix date and datetime types in the same query

CONSEQUENCEType mixing causes ValueError at query construction time, preventing data retrieval entirely for the affected query
