What is driving headline inflation this quarter? This breaks ABS CPI into all eleven expenditure groups, each weighted by its basket share, so you can see whether housing, food, or transport is doing the lifting.

History mode

Add start_period and end_period to walk the series back through time instead of returning only the latest point.

Returns

Every response uses the same {data, meta, links} envelope:

data: the answer, an object for a snapshot or a list when there is one row per entity.
meta: reference periods, retrieved_at, per-source attribution to reproduce on publish, and the stale flag.
links: a csv alternative when one is available.
