POST /api/contractsfinder/tenders/releases

Price: 40 credits

List Contracts Finder OCDS releases newest first — every notice published as a planning, tender or award stage release — optionally within a publication date window and limited to one stage, each with its buyer, parties with identifiers, addresses and contacts, tender terms, items, CPV codes, budget lines, documents and awards with suppliers and values.

How to use it

Use this to follow what was published, not to search: there is no keyword or buyer filter, so narrow with published_from and published_to and filter the rows yourself. One procurement appears once per notice it published, so group by ocid when you need processes rather than notices.

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: 1000)
• published_from string nullable — Earliest publication date, inclusive (examples: "2026-09-01", "2026-09-01T00:00:00")
• published_to string nullable — Latest publication date, inclusive; a bare date covers that whole day (examples: "2026-09-21", "2026-09-21T23:59:59")
• stage string nullable — Procurement stage of the release (one of: "planning", "tender", "award")

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.
