}About the offenevergaben.at API
The offenevergaben.at API provides structured access to Austrian public procurement data across 7 endpoints, covering contracts, suppliers, contracting authorities, and CPV industry categories. Use list_contracts to retrieve paginated contract summaries filtered by CPV code, NUTS region, notice type, date range, or keyword, and get_contract_detail to pull full contract fields including supplier, authority, contract type, and award value for any specific record.
Contract Search and Filtering
The list_contracts endpoint returns 20 contracts per page, sorted by last modification date descending. It accepts filters for CPV category codes (from list_categories), NUTS region codes as a comma-separated list (e.g. AT130,AT342), notice types (Ausschreibung for tender, Auftrag for award), a date range via date_from / date_to in YYYY-MM-DD format, and a search keyword matched against title, authority, and supplier. Each item in the items array includes the contract id, bezeichnung (title), auftraggeber (authority), lieferant (supplier), bieter (bidder count), summe (value), and aktualisiert (last modified date).
Contract and Entity Detail
get_contract_detail accepts a contract id and returns structured fields: Bezeichnung, Auftraggeber, Lieferant, Art des Auftrags, and more. Field availability varies by contract type and data availability — some records carry richer structured data than others. get_contracting_authority_detail and get_supplier_detail each return an entity profile alongside their contract history, total volume (gesamtvolumen), and contract count (anzahl_auftraege). The authority profile also exposes durchschnittliche_bieter, the average number of bidders per contract.
Suppliers, Authorities, and Categories
list_suppliers and list_contracting_authorities both return paginated lists sorted by total contract volume descending. Each item includes an id, name, national_id, anzahl_auftraege, and gesamtvolumen. Use these IDs as inputs to the respective detail endpoints. list_categories requires no inputs and returns all CPV division codes with German-language names (bezeichnung), aggregate volume (auftragsvolumen), and contract count (anzahl_auftraege) — useful for scoping searches by industry sector before querying list_contracts with a cpv filter.
- Monitor new public tenders in a specific Austrian region by filtering
list_contractswith NUTS codes anddate_from - Track a supplier's total awarded contract volume and history using
get_supplier_detail - Identify which contracting authorities award the most contracts by total volume via
list_contracting_authorities - Analyze government spending by CPV sector using
list_categoriesvolume and count fields - Retrieve full contract details including supplier and authority for a specific procurement record via
get_contract_detail - Build a competitive intelligence tool showing which suppliers win contracts in a given CPV category
- Cross-reference bidder counts (
bieter) and award values (summe) across authority profiles to spot procurement patterns

Does offenevergaben.at offer an official developer API?+
How does contract filtering work in `list_contracts`, and can I combine multiple filters?+
list_contracts endpoint accepts multiple optional parameters simultaneously: cpv (CPV division code), nuts (comma-separated NUTS region codes), types (comma-separated notice types such as Ausschreibung or Auftrag), date_from / date_to with date_type to scope by date field, and search for keyword matching against title, authority, or supplier. All are optional and combinable. Results are always paginated at 20 items per page.
