POST /api/austender/tenders/releases

Price: 20 credits

List AusTender OCDS contract releases newest first within a window of the contract's publish, start, end or last-modified date, each with the agency, the supplier with ABN and address, the value, the contract period, the UNSPSC classification and the procurement method.

How to use it

Use this to follow what was published or modified in a period, not to search: there is no keyword, agency or supplier filter, so narrow the window and filter the rows yourself. An amended contract appears once per release, so group by notice_id when you need contracts rather than releases. A window with no contracts returns an empty list.

Parameters

• access-token string required

Request body

• timeout integer — Max scrapping execution timeout (in seconds) (default: 300; min: 20; max: 1500)
• count integer required — Max number of results (min: 1; max: 2000)
• date_type string — Which contract date the window applies to (default: "published"; one of: "published", "start", "end", "modified")
• date_from string required — Start of the window, UTC (examples: "2026-09-15", "2026-09-15T00:00:00")
• date_to string nullable — End of the window, UTC (examples: "2026-09-16", "2026-09-16T00:00:00")

Errors

• 422 — The request body did not validate Check the fields against this schema. A URN with the wrong prefix is the most common cause.
• 408 — The request ran past its time limit Raise `timeout` in the request body, up to the maximum this endpoint documents. Lowering `count` or turning off the `with_*` flags also helps, because less work finishes sooner.
• 412 — The entity was not found, or a precondition failed Retrying will not help: either the entity does not exist, or the input points at a different one.
• 429 — Too many requests: a rate limit or a usage window is exhausted When the response carries an X-Retry-After header, wait that many seconds and retry: the same number is in the body as `detail.retry_after`, and the limit clears once that window passes. The message in the body names the limit that was hit.
• 500 — Something broke on our side Retrying will not help. If it keeps happening, send us the X-Request-ID from the response headers.
• 529 — Rate limit reached, or the endpoint is overloaded Wait at least 30 seconds, then retry.

Response headers

• X-Error — Error message text (present only on error)
• X-Request-ID — Unique request identifier
• X-Execution-Time — Execution time in seconds
• X-Result-Count — How many records the body carries. 0 means an empty result, which is a normal answer and not by itself an error. A non-zero count can come back together with X-Error when the failure happened partway through — read this header and X-Error independently.
• X-Total-Available-Results — How many records exist for this query, when the endpoint can say. On a `dry_run` request this is the answer and the body is empty. It saturates: the endpoint's documented maximum means 'at least that many', any smaller number is exact.
• X-Warning — Present when the request body carried keys this endpoint does not document. They were ignored, so any filter you meant to apply through them did not apply. Check the spelling against this schema and retry.
• X-Retry-After — Seconds to wait before retrying. Present only on 429.
