| 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. |

The number of exported company profiles will be up to 3000 per year. Number of users using the solution at the same time is expected to be below 10 because of the global nature of the usage.

- description:
- Trondheim Municipality, hereinafter referred to as the contracting authority, invites tenders for a contract in the project "Software for Leakage Reduction and Sewerage System Outflow in Municipality of Trondheim".Trondheim Municipality hereby announces that the competition is cancelled, cf. the Public Procurement Regulations § 21-4.In this competition, the contracting authority has set a qualification requirement that tenderers must have their tax and VAT matters in order, with an associated documentation requirement for the submission of an ordinary tax certificate and an extended tax certificate.During the pre-qualification process, it has become clear that the requirement to obtain an "extended tax certificate" creates challenges for foreign suppliers, as the companies must be established as a Norwegian registered foreign business (NUF).As the documentation requirement is currently formulated, foreign suppliers who have not established a NUF will, in reality, not have the opportunity to fully document that they meet the qualification requirement in the manner we have described. Alternative ways for foreign tenderers to document this have also not been specified. This is unfortunate and contributes to an unnecessary restriction of competition, without being required to achieve the purpose of the requirement. We therefore consider the requirement to be disproportionate and that it poses a risk of breaching the fundamental principles of the procurement regulations, particularly the principles of proportionality and equal treatment.It is not possible to change the documentation requirements for a qualification requirement at this time, as this would be a significant change that could affect the outcome of the competition. If the contracting authority must amend the tender documentation, and this cannot be done without making significant changes, the contracting authority will have a duty to cancel the competition.The contracting authority will make adjustments to the qualification requirement and then republish the competition shortly.

- description:
- The Fluid Mechanics group at NTNU wishes to extend our existing flow measurement capabilities to include the ability to simultaneously measure heat-release/temperature/species (scalar) fields in reacting flows with a new dual LIF system. We currently have a two stereoscopic PIV systems from LaVision GmbH which comprise of 2 low-speed lasers (10 Hz), 4 (25Mpx) PIV cameras and 3 (5Mpx) sCMOS cameras, frame grabbers, acquisition PCs, the timing and triggering units and the PIV acquisition and processing software. We now require integration of a high power LIF system that can measure multiple species. We wish to purchase a dual laser induced fluorescence (LIF) system for combustion diagnostics (OH and NH PLIF)) which needs to also be integrated with existing equipment in the Thermofluids research group at NTNU. The system must provide two separate dye lasers and two pump lasers, where one of the pump lasers must be able to provide at least 50-60 millijoules of energy per pulse in the ultraviolet (for OH-PLIF) whereas the second pump laser must be able to deliver 25-30 millijoules of energy per pulse. Image intensifiers and cameras, power meters, optics, acquisition and software that is compatible with our existing systems must be included. For this reason, we need to purchase it from the same manufacturer as our existing laser systems (due to the hardware we cannot integrate LaVision equipment with their competitors’ systems, and vice versa). Purchasing a similar system from another supplier would result in duplications of much of the hardware already in our laboratory but without the compatibility of combining the new hardware with our existing equipment to make a larger system with multiple lasers and cameras to perform simultaneous measurements. Integration with existing systems is essential to several ongoing projects funded by the EU. It is thus imperative that we purchase the new systems from the original supplier.

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.
