Open data
The data behind this site will be published as a documented, versioned dataset, so it can be joined against your own holdings rather than read off a chart. If you tender, this is the same source material the intelligence is built from — your own pipeline can consume it. The snapshot endpoint is live and serves sourced figures computed from ingested AusTender data. The collection endpoints below are not built yet.
Endpoints
JSON, CSV and Parquet on every collection endpoint. Only the snapshot endpoint is serving today; the rest are planned and are listed here so the shape is known in advance, not because they exist.
| Endpoint | Returns |
|---|---|
| /api/v1/contracts | Contract notices, filterable by year, state, domain, supplier and value |
| /api/v1/suppliers | Resolved supplier entities with ABN and classification |
| /api/v1/aggregates/state | State aggregates on a registered or delivery basis |
| /api/v1/aggregates/program | Program aggregates |
| /api/v1/reference/io-coefficients | Input-output coefficients and multipliers |
| /api/v1/reference/concordance | UNSPSC to ANZSIC to IOIG mapping |
| /api/v1/daily-sheet/{date} | The daily sheet as structured data |
| /api/v1/scenario/run | Run a scenario and get results with bands |
| /api/v1/snapshot/{name} | Page aggregates. Live now, sourced from AusTender |
Provenance
Every snapshot carries the time it was computed and the basis it rests on, and the response says whether it came from the database or fell back to a placeholder. A figure that cannot state its provenance is not served as though it can. Row-level provenance — source, retrieval timestamp, and which attribution layer produced a state assignment — lands with the collection endpoints.
