Tool Tokens
calculate_standstill_period ~369

Calculates the earliest date a contracting authority may award a contract after informing the unsuccessful bidders under § 134 GWB. Intended for requests where the user asks when the standstill period ends or from which date the award may be made. Input `absendung` is the date the bidder information is sent after the evaluation (not the contract notice date). Standstill: 10 days for electronic dispatch, 15 days for postal dispatch (rules as of 2026-07-14). Returns two end dates because review bodies differ on weekends: without a weekend shift (VK Bund) and shifted to the next working day (OLG Bremen); the Federal Court of Justice has not decided the question. `zuschlag_praktisch_*` and `praxishinweis` give the first working day on which the award can be made (weekends and public holidays skipped; state holidays via the optional `land`). Tender and participation deadlines are calculated by calculate_tender_deadline. Example user questions: "Wann endet die Wartefrist nach § 134 GWB?"; "Ab wann darf ich den Zuschlag erteilen?"; "Wie lange muss ich nach der Bieterinformation warten?"; "10 Tage Wartefrist — wann ist das genau?"

NameTypeReqDescription
absendungstringyesDate the § 134 GWB bidder information (Vorabinformation to unsuccessful bidders) is or was sent — not the contract notice date. ISO 2026-10-05 or German 05.10.2026.
elektronischboolean–Electronic or fax dispatch (10 days); false = postal (15 days). Default: true.
landstring–Optional federal state of the contracting authority; only used for the practical award date (state public holidays).

No output schema declared.

No examples provided.

calculate_tender_deadline ~428

Calculates the end date of a submission or participation deadline in an EU procurement procedure. Intended for requests where the user asks by which date bids or requests to participate are due, or whether the minimum period can be shortened. Applies the minimum periods and reductions (electronic submission, prior information notice, urgency) of § 15–16 VgV and § 10a–10b VOB/A EU, shifts the end date to the next working day per Regulation (EEC, Euratom) 1182/71 and explains each step (rules as of 2026-07-14). Covers VgV (services and supplies) and VOB/A section 2 EU (construction). The § 134 GWB standstill period is calculated by calculate_standstill_period. Example user questions: "Bis wann müssen Angebote eingehen?"; "Wie lange ist die Angebotsfrist bei einem offenen Verfahren nach VgV?"; "Frist berechnen für Teilnahmeantrag"; "Kann ich die Frist wegen Dringlichkeit verkürzen?"; "Wann endet die Angebotsfrist wenn ich heute veröffentliche?"

NameTypeReqDescription
absendungstringyesDate the contract notice is dispatched (ISO 2026-10-05 or German 05.10.2026). Day 0 — not counted towards the deadline.
dringlichkeitboolean–Duly substantiated urgency applies (overrides other reductions, sets minimum deadline). Default: false.
elektronischboolean–Electronic tender submission available (reduces deadline by 5 days where permitted). Default: true.
regelwerkstringyesLegal framework: vgv=Vergabeverordnung (services/supplies), voba=VOB/A Abschnitt 2 EU (construction).
verfahrenstringyesProcedure type. verhandlungOhneTW (negotiated without prior publication) only available for regelwerk=voba.
vorinformationboolean–Prior information notice published at least 35 days before (allows shorter deadlines). Default: false.

No output schema declared.

No examples provided.

check_company_status ~200

Checks for up to 25 German companies at once whether they are still active: verdict alive / dead / unknown, with the date of the status (as_of) and an explanation. Most companies are currently 'unknown'; 'unknown' does not mean alive. Intended for requests where the user wants to check a list of companies, e.g. cleaning CRM data or reviewing a supplier list. Example user questions: 'Are these 10 companies still registered?', 'Which of my supplier list are dissolved?' Full profiles per company come from get_company_profile. Max 25 companies per call.

NameTypeReqDescription
registersarrayyesList of company_number_norm values (max 25). Format: {CourtLetter}{4digits}_{HRB|HRA|PR|GnR|VR}{Nummer}, e.g. ['K1101_HRB52093'] (HRB 52093, Amtsgericht Hamburg). Court codes cannot be derived from c…

No output schema declared.

No examples provided.

check_eu_threshold ~439

Checks whether a public contract value is above the EU procurement threshold. Intended for requests where the user asks whether a contract must be advertised EU-wide or which procurement regime applies. Uses the thresholds valid 2026-01-01 to 2027-12-31 (Delegated Regulation (EU) 2025/2152); the EU revises them every two years, the previous values (valid 2024-01-01 to 2025-12-31) are returned in `schwelle_alt_eur` with an explanation in `schwelle_hinweis`. Returns whether the contract is above the threshold, the regime (VgV, VOB/A-EU, SektVO, KonzVgV) and, below the threshold, the sub-threshold limits for the federal government and Mecklenburg-Vorpommern (Art. 4 Directive 2014/24/EU). Which procedure types are permitted is answered by find_procurement_procedures. Key output fields: oberschwellig (boolean), schwelle_eur, regime, rechtsgrundlage, gueltigkeit. Example user questions: "Liegt mein Auftrag über dem EU-Schwellenwert?"; "Muss ich europaweit ausschreiben?"; "Wie hoch ist der Schwellenwert für Liefer- und Dienstleistungen?"; "Ab welchem Betrag gilt die VgV?"; "Unterschwellenvergabe oder EU-Vergabe?"

NameTypeReqDescription
auftraggeberstringyesType of contracting authority: bund=federal ministry, sonstige=state/municipality/other public body, sektoren=utilities (energy/water/transport), konzession=concession grantor.
leistungsartstringyesType of service (same name and values as in find_procurement_procedures): bau=construction, liefer=supply/goods, dienst=services, sozial=social and other special services. Alias accepted: leistung.
wertnumberyesEstimated contract value (net EUR). Accepts German thousands separator: 250.000 or decimal comma 250.000,50.

No output schema declared.

No examples provided.

count_working_days ~433

Counts the working days between two dates, or adds a number of working days to a start date, for any of the 16 German federal states with that state's public holidays (rules as of 2026-08-15). Intended for requests where the user asks how many working days lie between two dates or which date is n working days after a start date. Two modes: add (start + n working days → end date) and count (date range → number of working days). Not for procurement-law deadlines, which count calendar days under Regulation 1182/71; calculate_tender_deadline calculates those. Example user questions: "Wie viele Werktage liegen zwischen zwei Terminen?"; "Wann ist der 10. Werktag nach dem 05.10.2026 in Bayern?"; "Arbeitstage zwischen zwei Daten in NRW"; "Frist in Werktagen berechnen"; "Wie viele Arbeitstage hat der Oktober in Berlin?"

NameTypeReqDescription
bisstring–End of date range for mode=count (inclusive).
landstringyes2-letter German federal state code: BW=Baden-Württemberg, BY=Bayern, BE=Berlin, BB=Brandenburg, HB=Bremen, HH=Hamburg, HE=Hessen, MV=Mecklenburg-Vorpommern, NI=Niedersachsen, NW=Nordrhein-Westfalen,…
modestring–add: start + n working days → end date. count: count working days between von and bis.
samstagboolean–Count Saturday as a working day (for trade-law or rent-law deadlines). Default: false.
startstring–Start date for mode=add (ISO or German format).
tageinteger–Number of working days to add (positive = forward, negative = backward) for mode=add.
vonstring–Start of date range for mode=count.

No output schema declared.

No examples provided.

find_company ~498

Looks up a German company by its name or by an identifier and returns its profile and its company_number_norm, the key the other company tools take. Intended for requests where the user names a company ('Hornbach Baumarkt AG', optionally with the city in `ort`) or gives a register number with court ('HRB 12345 Hamburg', 'Amtsgericht Köln HRB 5604'), an EUID ('DEK1101R.HRB52093'), an LEI (20 characters), a German VAT ID ('DE117663151') or a MaStR actor ID ('ABR912345678901') and wants to know which company it is. Names match on the registered name; a name with its legal form (AG, GmbH, SE, KG …) is matched as given, a name without it is also tried with the common legal forms. When one company matches, the profile and ready follow-up calls are returned (by name: other close matches in `weitere_treffer`); when several match (status 'conflict' or 'candidates'), all candidates are listed with name, city and register status and none is picked. Limits: sole proprietorships (e.K.) are not found by name; a register number without the court (e.g. a bare 'HRB 12345') cannot be resolved. Example questions (German users): 'Gibt es die Hornbach Baumarkt AG noch?', 'Wer steckt hinter DEK1101R.HRB52093?', 'Finde die Firma mit USt-IdNr. DE117663151.'

NameTypeReqDescription
artstring–Kennungsart — optional, wird automatisch erkannt wenn weggelassen. Angeben, wenn die automatische Erkennung nicht greift.
kennungstringyesFreie Eingabe: Firmenname ('Hornbach Baumarkt AG'), Registernummer mit Gericht ('HRB 12345 Hamburg', 'Amtsgericht Köln HRB 5604'), EUID ('DEK1101R.HRB52093'), LEI (20-stelliger ISO-17442-Code), USt-I…
ortstring–Optional bei Namenssuche: Ort oder PLZ des Firmensitzes, grenzt gleichnamige Firmen ein ('München').

No output schema declared.

No examples provided.

find_procurement_procedures ~485

Lists which procurement procedure types are permitted for a contract, each with status frei (permitted), voraussetzung (permitted under conditions) or nein (not permitted) and its legal basis (GWB, VgV, UVgO; rules as of 2026-08-15). Intended for requests where the user asks which procedure type may or must be used for a given contract value, authority type and service category. Considers EU thresholds, the sub-threshold regime and special cases (single supplier, urgency, previous call without bids). With `bundesland` (e.g. BY or Bayern) the sub-threshold rules are chosen per state: federal authorities → UVgO, Mecklenburg-Vorpommern → its state rules, other states → general guidance plus the state law to check. The result is guidance; the choice of procedure stays with the contracting authority. Deadlines are calculated by calculate_tender_deadline, bid scoring by score_bids. Example user questions: "Welche Verfahrensart darf ich wählen?"; "Ist ein Verhandlungsverfahren zulässig?"; "Darf ich freihändig vergeben?"; "Wann ist ein Direktauftrag erlaubt?"; "Offenes oder nicht offenes Verfahren?"

NameTypeReqDescription
alleinstellungboolean–Only one company can provide the service (sole source / exclusive rights).
auftraggeberstringyesType of contracting authority (same as in schwellenwert).

leistungsartstringyesType of service (same as in schwellenwert).
nichtBeschreibbarboolean–Service cannot be specified sufficiently / requires conceptual or innovative solutions.
regelwerkstring–Optional override of the sub-threshold framework: mv=Mecklenburg-Vorpommern, bund=federal authority, anders=any other state (generic guidance). Usually empty, since bundesland selects the framework.…
wertnumberyesEstimated contract value (net EUR).

get_company_financials ~373

Returns the financial history of a German company from its filed annual accounts, one row per fiscal year: Bilanzsumme (total assets), Eigenkapital (equity), Jahresüberschuss (net income), Umsatz (revenue), Mitarbeiter (employees). Intended for requests where the user asks about revenue, equity, profit or headcount of a company over the years. Small companies may legally omit revenue; NULL means the figure was not published (not zero). Example user questions: 'What were the revenues of K1101_HRB52093 (HRB 52093, Amtsgericht Hamburg) in 2022?', 'Show me the equity history of this company'. Whether the company is still active is answered by check_company_status.

NameTypeReqDescription
from_yearinteger–Oldest fiscal year to include (e.g. 2018). Optional.
registerstringyescompany_number_norm — the unique register key for a German company. Format: {CourtLetter}{4digits}_{HRB|HRA|PR|GnR|VR}{Nummer}, Example: 'K1101_HRB52093' is HRB 52093 at Amtsgericht Hamburg (court co…

No examples provided.

get_company_profile ~330

Returns the register profile of one German company: name, address, legal form, register court, WZ industry code, website and alive verdict (active/dead/unknown) with the date of the status (as_of). Intended for requests where the user asks who a company is, where it is registered or whether it is still active, and the company_number_norm is known (otherwise find_company resolves it first). Example user questions: 'Wer steckt hinter HRB 52093, Amtsgericht Hamburg?' (key K1101_HRB52093), 'Welche Adresse hat K1101_HRB52093?', 'Is this company still active?' Related: check_company_status checks up to 25 companies at once; get_company_financials returns the financial history.

NameTypeReqDescription
registerstringyescompany_number_norm — the unique register key for a German company. Format: {CourtLetter}{4digits}_{HRB|HRA|PR|GnR|VR}{Nummer}, Example: 'K1101_HRB52093' is HRB 52093 at Amtsgericht Hamburg (court co…

get_tender ~370

Returns the details of one tender notice by its uid: title, contracting authority (name, address, email, phone, website), all dates, CPV/NUTS codes, AI summaries (short, medium, long, plain language), key deliverables, risk flags, eligibility summary and the link to the original portal. Intended for requests where the user asks about one specific tender, e.g. its deadline, contact or scope. Input: the uid from search_tenders or list_tenders results (format source:id, e.g. bkm:675fa09d-…, ted:427373-2026, bund:eVergabe/888110). The response also contains the numeric notice_id; the list of procurement documents, the AI-structured sections and the Q&A are returned by get_tender_documents. Limits: 30 requests per 10 minutes, 200 per day per IP. Example user questions: "Zeig mir Details zur Ausschreibung bkm:675fa09d-5152-46c5-9967-ed104d16276b"; "Was sind Frist und Vergabestelle für diese Bekanntmachung?"; "Welche Unterlagen und Fristen hat die Ausschreibung XYZ?"; "Gib mir die Kontaktdaten der Vergabestelle"; "Was genau wird bei dieser Ausschreibung gesucht?"

NameTypeReqDescription

get_tender_counts ~199

Returns the counts of tender notices across the whole data set: open, urgent (deadline within 14 days), awarded and total, plus the size of the semantic search index, the embedding model name and the health of the portal links. Intended for requests where the user asks how many tenders are open overall or how large and current the tender data is. No parameters, so no filter by topic, region, CPV code or deadline: counts for a topic or region (e.g. open photovoltaic tenders per Bundesland) are the `total` and `by_bundesland` fields of a list_tenders result. Key output fields: open_count, urgent_count, awarded_count, total_count, index_size. Example user questions: "Wie viele Ausschreibungen sind aktuell offen?"; "Wie aktuell ist die Vergabe-Datenbank?"; "Gibt es dringende Ausschreibungen mit Frist in 14 Tagen?"

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

get_tender_documents ~332

Returns the complete record of one tender: all fields of get_tender plus AI-structured sections (description, criteria, …), a Q&A list (e.g. 'Is a security clearance required?'), topic facets and the list of procurement documents (file names, sizes, MIME types, download status). Intended for requests where the user asks which documents a tender has, or wants a structured summary or the Q&A of the tender documents. The files themselves are not returned; they are available via the portal link (`procedure_room_url` or `detail_url`). `assistant_ready` = true means the documents were downloaded and analysed, so `sections`, `qa` and `eligibility_summary` are filled; when false they are empty. `documents[].download_status`: ok = stored at Overfit, pending = not fetched yet, failed/skipped = could not be fetched. Input: the numeric notice_id (field `notice_id` in search_tenders and get_tender results, field `id` in list_tenders results), not the string uid. Limits: 30 requests per 10 minutes, 200 per day per IP (shared with get_tender). Example user questions: "Welche Unterlagen gibt es für diese Ausschreibung?"; "Gibt es eine strukturierte Zusammenfassung der Vergabeunterlagen?"; "Welche Fragen und Antworten sind zu dieser Ausschreibung bekannt?"

NameTypeReqDescription

No output schema declared.

No examples provided.

list_public_holidays ~180

Lists the public holidays of a year in Germany, nationwide or for one of the 16 federal states including state-specific holidays (rules as of 2026-08-15). Intended for requests where the user asks which public holidays fall in a year or month in a given state. Key output fields: datum (ISO date), name (German), bundesweit (boolean). Working days between dates are counted by count_working_days. Example user questions: "Welche Feiertage gibt es 2026 in Bayern?"; "Feiertage in Berlin auflisten"; "Welche gesetzlichen Feiertage hat Sachsen?"; "Gibt es im Oktober 2026 Feiertage in NRW?"

NameTypeReqDescription

landstring–2-letter federal state code. Omit for nationwide-only holidays.

No output schema declared.

No examples provided.

list_tender_portals ~143

Lists the tender portals the notices come from (e.g. EU TED, the federal portal) with the number of notices per portal and status. Intended for requests where the user asks which portals are covered or how many notices come from a given portal. Counts use the same rules as list_tenders (open counts exclude expired deadlines). One optional parameter (include_dead). Example user questions: "Welche Vergabeportale sind in der Suche enthalten?"; "Wie viele EU-Ausschreibungen sind verfügbar?"; "Woher kommen die Daten in der Vergabe-Suche?"

NameTypeReqDescription
include_deadboolean–Include notices with dead portal URLs in the counts.

No output schema declared.

No examples provided.

list_tenders ~761

Lists German and EU public tender notices by exact filters (status, Landkreis, CPV prefix, sector, contracting authority, deadline within 14 days and more), with optional keyword search (`q`, full text, not by meaning) and sorting, e.g. newest publications first. Intended for structured listings such as all open IT tenders (cpv_prefix=72), all tenders in a Landkreis with a deadline in the next 14 days, or the latest publications. Search by topic or meaning is done by search_tenders. Data: 100,000+ notices (20,000+ open), new notices daily (federal portal every 30 minutes). Each hit has `id` (the numeric notice_id, input of get_tender_documents) and `uid` (input of get_tender). The same tender published on several portals appears once per portal with different uids; hits with the same title, contracting authority and deadline are one tender. Counting: the result carries `total` (number of all matching notices, so counting needs no paging) and, on the first page when at most 500 notices match, `by_bundesland` (matching notices per Bundesland). Limits: offset up to 2000; 40 requests per 10 minutes and 300 per day per IP. Example user questions: "Liste alle offenen Ausschreibungen mit Frist in den nächsten 14 Tagen"; "Zeig alle Vergaben aus dem Landkreis München"; "Welche Ausschreibungen wurden zuletzt veröffentlicht?"; "Alle offenen IT-Vergaben (CPV 72) sortiert nach Veröffentlichungsdatum"; "Liste alle Bekanntmachungen der Bundesagentur für Arbeit"

score_bids ~484

Calculates scores and a ranking of procurement bids from bid prices and given quality scores, with one of the UfAB scoring methods (§ 127 GWB, § 58 VgV; UfAB guideline methods, 2016 edition). Intended for requests where the user wants to compute a bid evaluation matrix or check how the ranking reacts to price changes. `methode`: gewichtet = percentage weights for price and quality (e.g. 'Preis 40 %, Leistung 60 %' → gewichtLeistung=60); einfach = quality points per euro (Leistung/Preis ratio), used when no weights are given; erweitert = leading group of close bids plus a tie-break criterion. One method per call (default einfach). Also returns a sensitivity analysis: how far the price of the top-ranked bid can rise before the ranking changes. The tool does not assess quality (the quality scores must be supplied) and does not make the award decision, which stays with the contracting authority. Key output fields: result.ergebnis.sieger (top-ranked bid), result.ergebnis.zeilen[] (ranking with kennzahl and rang), result.sensitivitaet, legal_basis. Example user questions: "Welches Angebot gewinnt nach Preis-Leistungs-Verhältnis?"; "Wertungsmatrix nach UfAB berechnen"; "Zuschlag auf das wirtschaftlichste Angebot ermitteln"; "Sensitivitätsanalyse der Angebotswertung"; "Führungsgruppe nach erweiterter Richtwertmethode"

search_tenders ~729

Searches German and EU public tenders by meaning: returns notices ranked by how well they match a natural-language description (German or English) of what the user offers or looks for. Intended for requests by topic, product, service or industry. Each hit has an AI summary, submission deadline, contracting authority, place, CPV/NUTS codes, the uid (input of get_tender) and the numeric notice_id (input of get_tender_documents). Coverage: 100,000+ notices (20,000+ open), collected daily from EU, federal, state and municipal portals; the semantic index covers 140,000+ notices, so the newest publications are listed by list_tenders (order_by=publication_desc). Filter-only listings without a topic are done by list_tenders. The same tender published on several portals appears once per portal with different uids; hits with the same title, contracting authority and deadline are one tender. Limits: about 10 searches per day per IP, then HTTP 429 with Retry-After (keyword search via the `q` parameter of list_tenders has a separate limit). Main filters: Bundesland, status, cpv, nuts, deadline_after/before, notice_type. Example user questions: "Welche offenen Ausschreibungen gibt es für IT-Dienstleistungen in Schleswig-Holstein?"; "Suche Vergaben für Gebäudereinigung mit Frist nach Oktober 2026"; "Finde Bekanntmachungen für Straßenbau in Bayern"; "Gibt es aktuelle Ausschreibungen im Bereich Softwareentwicklung?"; "Zeig mir laufende Vergabeverfahren für medizinische Geräte"
