| 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. |

- Avinor AS - RFI - Demonstration of zero and low emission aircraft suitable for the regional aviation sector
- description:
- Avinor and the Civil Aviation Authority of Norway (CAA Norway) have jointly established the International Test Arena for zero- and low-emission aircraft in Norway. The purpose of the test arena is to accelerate implementation of zero and low emission aviation by reducing barriers for operational testing and demonstration. Through the test arena the parties aim to gain and share knowledge, prepare the aviation ecosystem, and provide a foundation for scaling new technologies. The test arena provides the market with a common point of contact in Avinor and CAA Norway, as well as a joint process from concept development to testing and flight demonstrations. This includes infrastructure, airspace, energy supply, and regulatory facilitation for national and international stakeholders who wish to test and demonstrate zero- and low-emission aircraft in Norway. Avinor will provide relevant infrastructure, airspace, and access to energy, while CAA Norway will offer regulatory facilitation, including a regulatory sandbox. The test arena will, in principle, cover the entire Norwegian airport network and airspace. Specific geographical locations for the establishment of test operations will be decided in dialogue with market participants, based on their needs, as well as assessments of technological maturity and the availability of relevant energy. For further information, please see attachment, attached hereto, or contact; testarena@avinor.no

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.
