| 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. |
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. |

- Framework agreement for investigations into working conditions at footwear factories
- description:
- The Contracting authority is seeking to enter into a framework agreement with a service provider which can conduct investigations into labour rights violations and labour practices primarily at footwear manufacturing facilities owned by companies in which the GPFG has holdings. Currently, the GPFG has holdings in seven footwear manufacturers. However, under the agreement, the contracting authority may also request investigations of other similar types of manufacturing facilities, such as textile and garment factories. The investigations will provide a basis for determining whether companies’ conduct can lead to exclusion or observation under the human rights criterion of the ethical guidelines. The investigations may be carried out in a number of countries, including but not limited to Vietnam, Indonesia, Taiwan, Cambodia, Bangladesh and India. The budget is estimated to EUR 50 000 – 120 000 per year, with a maximum value of EUR 500 000 during the entire contract length of maximum four years (2+1+1). The contract is not exclusive. For further information on the scope and content of the procurement, please see appendix 1.

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.
