Record review date: 2026-09-07

One API response for Bihor was read and its structure checked. This does not validate the whole dataset.

1. Open the API example and identify geo, time, age and sex dimensions.
2. Replace RO111 with the required NUTS 3 code and check its returned label.
3. Read values with units and flags. Pin a year rather than the latest period for reproducibility.
