For software and dashboards: Read the operation descriptor.

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.

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.
