| 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. |

- Intensjonskunngjøring-Multi-scalar Imaging System
- 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.
