classifying is VARIABLE:KEY, e.g. GP19A2:GP19-05, taken from /destatis/variables/{code}/values. Repeat the parameter for more than one variable (five classifying plus one regional). A key that is not in that value list is refused here with HTTP 400 and is never sent upstream: GENESIS answers Status 0 and the whole cube for an invalid classifying key. The answer may be served from cache; a cache hit is free and is not counted against the budget.curl --location 'https://sugra.ai/api/v1/destatis/table/42131-0003?start_year=2020&end_year=2024&contents=PRODAW%2CUNT006&classifying=GP19A2%3AGP19-05' \
