For software and dashboards: Read the operation descriptor. The JSON GET template is https://allemannsdata.com/wiki/api/v1/kilder/doffin/search_doffin?query=&types={types}&statuses={statuses}&contract_nature={contract_nature}&cpv_codes={cpv_codes}&locations={locations}&buyer={buyer}&winner={winner}&date_from={date_from}&date_to={date_to}&sort_by=RELEVANCE&page=1&hits_per_page=10&include_placeholders=false&limit=25&offset=0. Open this exact request as JSON.

Parameter	Requirement	JSON type	Description
`query`	optional	string	Free-text search (Norwegian or English), e.g. "IT-drift", "snørydding", "rammeavtale konsulent". Start here.
`types`	optional	union	Filter by notice type. Parent types: PLANNING, COMPETITION, RESULT. Specific types: ANNOUNCEMENT_OF_COMPETITION, DYNAMIC_PURCHASING_SCHEME, QUALIFICATION_SCHEME, ANNOUNCEMENT_OF_INTENT, PRE_ANNOUNCEMENT, ADVISORY_NOTICE, NOTICE_ON_BUYER_PROFILE, ANNOUNCEMENT_OF_CONCLUSION_OF_CONTRACT, CHANGE_OF_CONCLUSION_OF_CONTRACT, CANCELLED_OR_MISSING_CONCLUSION_OF_CONTRACT. Use ["COMPETITION"] + statuses=["ACTIVE"] for open tenders.
`statuses`	optional	union	ACTIVE (open for bids), EXPIRED, AWARDED, CANCELLED.
`contract_nature`	optional	union	WORKS, SERVICES and/or SUPPLIES.
`cpv_codes`	optional	union	8-digit CPV codes, e.g. ["45000000"]. Matches the code and its children. Find codes with search_cpv_codes(). Best combined with a free-text query.
`locations`	optional	union	NUTS-style location ids, e.g. ["NO060"] (Trøndelag), or "anyw" for non-location-bound. See list_location_codes().
`buyer`	optional	union	Buyer organization full name(s) exactly as written on notices, e.g. ["Trondheim kommune"]. Resolved to Doffin's internal buyer id via a free-text lookup; names that match no buyer are reported in "note" and, if none match, no results are returned (rather than an unfiltered search). Pass the 32-hex buyer id from a result's buyer field directly to skip the lookup.
`winner`	optional	union	Doffin's internal supplier id (32-hex). Winner names cannot be used - they are not present in search results to resolve against.
`date_from`	optional	union	Publication date lower bound, "YYYY-MM-DD".
`date_to`	optional	union	Publication date upper bound, "YYYY-MM-DD".
`sort_by`	optional	string	RELEVANCE (default), PUBLICATION_DATE_DESC, PUBLICATION_DATE_ASC, DEADLINE, ESTIMATED_VALUE_ASC, ESTIMATED_VALUE_DESC.
`page`	optional	integer	1-based page number.
`hits_per_page`	optional	integer	1-50 (default 10).
`include_placeholders`	optional	boolean	By default, hits whose buyer fields look like unfilled eForm template values (org id 123456789, placeholder buyer names) are dropped from the results as junk. Set True to keep them, each flagged with "possible_placeholder": true.
`limit`	optional	integer	Gateway page size; default 25, maximum 100.
`offset`	optional	integer	Number of list items to skip; default 0.

Generated JavaScript, Python and response structure

Use JSON when the user requests code, machine-readable data, value extraction or further computation. Use the HTML GET page to identify the correct source and verify parameters.

Jevnaker ungdomsskole, totalentreprise
description:
Konkurransen gjelder levering av totalentreprise for ny Jevnaker ungdomsskole. Anskaffelsens verdi anslås til NOK 120 mill. eks. mva + opsjon op NOK 15 mill. eks. mva. Volumet er et estimat og er ikke bindende for oppdragsgiver. Oppdragsgiver tar forbehold om avlysning av konkurransen, blant annet i forbindelse med budsjettmessig dekning og politisk godkjenning. Klimabelastningen er identifisert til å omfatte de fleste temaene i listen over. Klima og miljøbelastningen for prosjektet er redusert ved å utarbeide MOP med krav knytte til temaene. De største faktorene vil være klimagassutslipp fra materialer og energibehov til bygget. Det er i MOP stilt krav til 20 % reduksjon av klimagassutslipp fra materialer i forhold til DFØ sin referanse for skolebygg. Referanseverdiene representerer dagens praksis. Det er også stil krav til netto energibehov 20 % lavere enn TEK 17. Dette er også en forbedring av dagens praksis knyttet til byggets energibehov. Prosjektet har derfor stilt krav både til energi og materialer som fører til en redusert klima- og miljøbelastning. Det er også krav som gjør at en konkurranse på disse områdene ikke vil føre til vesentlig lavere miljøbelastning.I tillegg har MOP krav til hvert tema, som reduserer klima og miljøbelastningen til prosjektet ytterligere. I sum vil disse kravene gi en bedre reduksjon av klima og miljøbelastning, enn tildelingskriterier. Jevnaker kommunen sin vurdering er derfor at for å redusere klima- og miljøbelastningen for denne anskaffelsen benyttes unntaksbestemmelsen i FOA § 7-9 (4), da det er klart at bruk av klima- og miljøkrav har en bedre klima- og miljøeffekt enn bruk av tildelingskriteriet som beskrevet i FOA § 7-9 (2). For nærmere informasjon viser vi til anskaffelsesdokumentene.

How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the search_doffin lookup

Replace the placeholders in the HTML GET template; remove optional parameters you do not need.
Check types, units, limits and ID formats in the parameter table.
Follow linked results to canonical pages before combining sources.

Misreading to avoid: An empty list means "no results for this lookup". An error message or unavailable source does not mean the data does not exist.

Source-specific next step

Follow the notice ID to the canonical page; use CPV and location codes to narrow broad free-text searches.

Go to the source page for other operations. Use the JSON template only after the HTML result shows that the parameters and source are correct.
