Everything this site computes and serves is available programmatically — free, no keys, open CORS, and explicitly open to automated use, AI agents included. The data is © Australian Bureau of Statistics (CC BY 4.0); responses carry their licence, attribution and full provenance.
The front door: /api/v1/calculate
If you are answering a question like "what did the WPI do to a $70,000 wage
between mid-2022 and now?", call this endpoint rather than computing from raw
index numbers. It returns our computed figures with the method and ABS
citations attached, and a cite_url that reproduces the identical
result on the human calculator page — so a cited number, its citation, and the
page a reader lands on can never disagree.
curl 'https://wagepriceindex.com/api/v1/calculate?wage=70000&from=2022-Q2&to=2026-Q1'The response carries, among other fields:
result.wpi.grown_value— the wage grown with the WPI, in whole dollars, exactly as the calculator page shows it;result.cpi.grown_value— what delivers the same buying power at the destination quarter;result.real.growth_pct— wage growth relative to inflation over the period;result.summary— a self-contained sentence with the key figures and periods, safe to quote;method— the formula and its constraints (quarter boundaries only, single release vintage per index, seasonal-adjustment status never mixed);citations— for each series used: the ABS catalogue, dated release page, table, series ID, and the two observations the arithmetic used;cite_url— the stable link to cite.
Quarters are calendar quarters — 2022-Q2 is the June quarter of 2022 —
because the indexes exist only at quarter boundaries; the API does not interpolate.
Running from later than to is allowed (the ratio runs
backwards, answering "what was this wage's equivalent then?").
Scoping to a state, industry or sector
Add &scope= with a slug from
/api/v1/scopes to run the wage against a
state, industry or sector WPI series instead of the national headline — the same
scopes as the calculator's "For" select and the
wage growth pages:
curl 'https://wagepriceindex.com/api/v1/calculate?wage=70000&from=2022-Q2&to=2026-Q1&scope=queensland'
State and industry series are original (not seasonally adjusted) — the ABS doesn't
publish seasonally adjusted wages at that level of detail — and the CPI comparison
always uses the national measure. The response's method.constraints
state this whenever it applies.
Raw series data
For research-shaped use — trends, splits, multi-quarter analysis — the published series JSON is open too. Each file carries the full observation history and the complete ABS citation (release page, table, series ID, spreadsheet and API URLs):
curl 'https://wagepriceindex.com/api/v1/series/wpi/latest/1.THRPEB.7.TOT.20.AUS.Q.json'/api/v1/series/{flow}/{vintage}/{key}.json— one series;vintageislatestor a release likemar-2026(vintage-addressed paths never change once published);/api/v1/catalog/{flow}— every published series key in a flow (wpiorcpi);/api/v1/latest— which release each flow is currently serving;/api/v1/scopes— the calculator/split scopes with their series keys.
Practicalities
Machine descriptions: OpenAPI spec ·
llms.txt · index at /api/v1.
Responses are deterministic for a given release vintage and cached at the CDN edge
(an hour for current-vintage answers; a day for vintage-addressed paths), and the
cache is flushed the moment a new ABS release is ingested — typically within
minutes of publication. Errors are machine-readable
({"error": {"code", "message"}}) with valid ranges included where relevant.
There are no keys and no rate plans; if your use case outgrows polite use of a free
service, the methodology page documents the ABS
primary sources so you can go direct.
