TenderNed | Apiosk Gateway

About

TenderNed is where Dutch contracting authorities are legally required to publish their tenders, so it is the single authoritative feed of Dutch public-sector buying intent. `publicaties` is the flagship resource: search the whole archive with `search` (free text), `cpvCodes` (the EU Common Procurement Vocabulary, with check digit — e.g. 85000000-9 for health and social work), `procedure` (OPE openbaar, NOP niet-openbaar, OH open house, and nine more), `typeOpdracht` (W werken, L leveringen, D diensten), and date windows on either publication or closing (`publicatieDatumVanaf`/`publicatieDatumTot`, `sluitingsDatumVanaf`/`sluitingsDatumTot`, or the `publicatieDatumPreset` shorthands AF7 and AF30). Append a publicatieId to the same path for that notice's full record — awarding authority, description, CPV and NUTS codes, procedure, legal framework, start and completion dates, closing date, whether it is European or national, whether it was awarded or terminated early — and append /documenten or /pdf for the tender documents themselves. `nutscodes` resolves the NUTS region codes those notices carry down to the municipalities they cover. `rss/laatste-publicatie.rss` is an Atom feed of the most recent publications, for an agent that wants to watch rather than search. Upstream is free and unauthenticated; Apiosk meters and charges per call so an agent needs no TenderNed integration of its own.

Method	Path	Description	Cost
GET	/rss/laatste-publicatie.rss	The most recent TenderNed publications as an Atom feed — title, awarding authority, publication date and a link to each notice. The way to watch for new Dutch tenders without re-running a search. Returns application/atom+xml, not JSON.	$0.03 default	View details
GET	/v2/nutscodes	The NUTS region code tree used by every notice's nutsCodes field, from NL (Nederland) down through the four landsdelen and twelve provinces to the COROP regions — each leaf listing the municipalities it covers. What turns a code like NL112 in a notice into "Delfzijl en omgeving: Appingedam, Delfzijl, Loppersum".	$0.02 default	View details
GET	/v2/publicaties	Search Dutch public tender notices, or look one up in full. Search the whole archive (~145,000 notices) with any combination of search (free text over title, buyer and description), cpvCodes, procedure, typeOpdracht, and a window on either the publication date or the closing date. Supply publicatieId instead to fetch that one notice's complete record: awarding authority, full description, CPV and NUTS codes, procedure and legal framework, start/completion dates, closing date, national or European, and whether it was awarded or terminated early. A caller building the raw request path directly (not through structured parameters) can also append further segments after the publicatieId at the same price: /documenten for the list of tender documents with their download links, and /pdf for the official publication PDF. Results are paged with page/size and come back with totalElements and totalPages.	$0.05 default	View details
