Overfit — German tenders & procurement law

Semantic search over German and EU public tenders: returns notices ranked by how well they match a natural-language description (German or English), each with AI summary, submission deadline, contracting authority, place, CPV/NUTS codes, the stable uid and the numeric notice_id. Coverage: 190,000+ notices in the Overfit database (30,000+ open), collected every day from EU TED, federal, state and municipal portals; the semantic index covers 100,000+ notices. Publications newer than the index are found by vergabe_liste (order_by=publication_desc). Suited to requests by topic, keyword or industry. Structured filter queries without a topic description are the job of vergabe_liste. The same tender is often published on several portals (e.g. Vergabe-Hub DE 'bkm:…' and EU TED 'ted:…') and then appears once per portal with different uids; hits with the same title, contracting authority and deadline are one tender. Limits: ~10 semantic queries per day per IP (afterwards 429 with Retry-After; vergabe_liste with the q parameter offers keyword search under a separate limit). Key filter parameters: 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"

Paginated list of German and EU tender notices filtered by status, Landkreis, CPV prefix, sector, authority, urgency and more, with optional keyword fulltext search (not semantic). Data: 190,000+ notices (30,000+ open), new notices added every day (federal portal every 30 minutes). Each hit carries `id` (= the numeric notice_id that vergabe_bekanntmachung_voll takes) and `uid` (the input of vergabe_bekanntmachung). The same tender is often published on several portals (e.g. Vergabe-Hub DE 'bkm:…' and EU TED 'ted:…') and then appears once per portal with different uids; hits with the same title, contracting authority and deadline are one tender. Suited to structured listings, e.g. all open IT tenders (cpv_prefix=72), all urgent tenders in a Landkreis, the latest publications sorted by date. Matching by meaning is done by vergabe_suche. Limits: offset up to 2000; 40 requests / 10 min and 300 / 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"

Returns full detail for one notice: title, 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 original portal URL. Input: the uid from vergabe_suche or vergabe_liste results (format source:id, e.g. bkm:675fa09d-…, ted:427373-2026, bund:eVergabe/888110). The response also carries the numeric notice_id. The document list, AI-structured sections and Q&A of a notice are returned by vergabe_bekanntmachung_voll (input: notice_id). Rate limit: 30 requests / 10 min, 200 / 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?"

Complete record of one tender: all fields of vergabe_bekanntmachung plus the AI-structured sections (description, criteria, …), a Q&A list (e.g. 'Is a security clearance required?'), topic facets, and a list of available procurement documents (filenames, sizes, MIME types, download status). Field guide: `assistant_ready` = true means the procurement documents are downloaded and analysed, so `sections` (AI-structured summary), `qa` and `eligibility_summary` are filled; when false these stay empty and the notice fields and summaries are what is available. `documents[].download_status`: ok = file stored at Overfit, pending = not fetched yet, failed/skipped = could not be fetched. The files themselves are not returned; they are available via the notice's portal link (`procedure_room_url` or `detail_url`). Input: the numeric notice_id (not the string uid 'source:id' of vergabe_bekanntmachung). Every Vergabe result carries both: field 'notice_id' in vergabe_suche and vergabe_bekanntmachung results, field 'id' in vergabe_liste results. Rate-limited at 30 requests/10 min and 200/day per IP (same bucket as notice detail).

Returns live counts of open, urgent (deadline ≤ 14 days), awarded and total notices plus URL health distribution and semantic model name (Stand: live). Suited to questions about database size and current tender counts. No parameters, no rate limit. Key output fields: open_count, urgent_count, awarded_count, total_count, index_size.

Per-portal notice counts by status: shows which portals (e.g. TED EU, Vergabe-Bund) are covered and how many notices each contributes. Counts match vergabe_liste exactly (same visibility gate, same stale-deadline exclusion). No rate limit. One optional parameter. Example user questions: "Welche Vergabeportale sind in der Suche enthalten?"; "Wie viele EU-Ausschreibungen sind verfügbar?"; "Woher kommen die Daten in der Vergabe-Suche?"

Answers with the CURRENT EU threshold for the contract: thresholds valid 2026-01-01 to 2027-12-31 (Delegierte VO (EU) 2025/2152) — the EU adjusts them every two years; the values that applied until 2025 (e.g. 221,000 / 143,000 / 5,538,000 EUR) are outdated. Returns whether the contract is above the threshold, the procurement regime (VgV, VOB/A-EU, SektVO, KonzVgV) and — if below threshold — sub-threshold limits for the federal government and Mecklenburg-Vorpommern (Art. 4 RL 2014/24/EU). `schwelle_alt_eur` is the previous value (valid 2024-01-01 to 2025-12-31), explained in `schwelle_hinweis`. Suited to the question whether a contract requires EU-wide publication or stays within national sub-threshold rules. The permitted procedure types are determined by verfahrenswahl_ermitteln. 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?"

Returns the effective end date for the submission or participation deadline (shifted to next working day per VO 1182/71) with per-step legal reasoning for each reduction applied — electronic submission, prior information notice, urgency (§ 15–16 VgV; § 10a–10b VOB/A EU; Stand 2026-07-14). Suited to the question on which date a submission deadline falls or whether the minimum period can be shortened. Works for VgV (services/supplies) and VOB/A Abschnitt 2 EU (construction) procedures. The § 134 GWB standstill period after the bidder information is computed by vergabe_wartefrist. 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?"

Earliest date a contracting authority may award the contract after informing the unsuccessful bidders (§ 134 GWB). `absendung` = the date the § 134 GWB bidder information is sent after the bids were evaluated (not the contract notice date); the period starts with that dispatch. Returns both interpretations of the § 134 GWB standstill: the strict end date (no weekend shift, per VK Bund) and the conservative one (shifted to next working day, per OLG Bremen) — electronic dispatch 10 days, postal 15 days (Stand 2026-07-14). Suited to the question on which date a contract may be awarded after informing unsuccessful bidders. The BGH has not resolved the weekend-shift question; the conservative date is the safer one. `zuschlag_praktisch_*` + `praxishinweis` give the first working day on which the award can practically be made (weekends and public holidays skipped; state holidays via the optional `land`). Tender and participation deadlines are computed by vergabe_fristen_berechnen. 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?"

Returns a working-day count or a target date for any of the 16 German federal states, using the complete holiday set for that state (Gauß Easter formula; Stand 2026-08-15). Two modes: add (start + n working days → end date) and count (date range → working-day count). Suited to questions how many working days lie between two dates or on which date a deadline falls after n working days. Procurement-law deadlines count calendar days under VO 1182/71 and are computed by vergabe_fristen_berechnen. 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?"

Returns a list of procurement procedures with status frei (available), voraussetzung (available under conditions), or nein (unavailable) and the legal basis for each (§ GWB / § VgV / UVgO; Stand 2026-08-15). Suited to the question which procedure type is required or permissible for a given contract value, authority type and service category. With `bundesland` (e.g. BY or Bayern) the tool selects the sub-threshold rules itself: federal authority → federal rules (UVgO), Mecklenburg-Vorpommern → its own state rules, every other state → generic guidance with the state law to check. Takes into account EU thresholds, sub-threshold regime and special-case flags (sole source, urgency, prior call with no tenders). Deadlines and bid scoring are computed by vergabe_fristen_berechnen and wertungsmatrix_berechnen. 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?"

Calculation aid for bid evaluation: computes the score and ranking of bids under the chosen UfAB scoring method — einfach (L/P ratio), erweitert (leading group) or gewichtet (weighted normalisation) — plus a sensitivity analysis showing how far the price of the top-ranked bid can rise before the ranking changes (§ 127 GWB, § 58 VgV; UfAB-Richtwertmethoden Stand 2016). Input: bid prices and existing quality scores; output: the arithmetic ranking. Evaluating quality and the award decision itself remain with the contracting authority. `methode`: percentage weights for price and quality (e.g. 'Preis 40 %, Leistung 60 %') correspond to gewichtet with gewichtLeistung=60; without weights, best quality per euro corresponds to einfach (Leistung/Preis ratio); close bids decided by a leading group plus a tie-break criterion correspond to erweitert. One method per call (default einfach). The tool scores bids; it does not assess quality, so quality scores have to exist already. 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"

TEMPORARILY UNAVAILABLE: identifier resolution is being set up (expected from 2026-10-07); until then this tool answers status 'nicht_verfuegbar'. Meanwhile firma_profil, firma_status and firma_finanzen work only with a company_number_norm you already have (format {CourtLetter}{4digits}_{HRB|HRA|PR|GnR|VR}{Nummer}, e.g. 'K1101_HRB52093' = HRB 52093, Amtsgericht Hamburg). Court codes cannot be derived from city names, so a register number with court (e.g. 'HRB 52093 Hamburg') can be looked up again from 2026-10-07. Turns any identifier of a German company into its profile and its company_number_norm (the key the other firm tools take): register number with court ('HRB 12345 Hamburg', 'Amtsgericht Köln HRB 5604'), EUID ('DEK1101R.HRB52093'), LEI (20 characters), German VAT ID ('DE117663151') or MaStR actor ID ('ABR912345678901'). Returns the company profile and ready follow-up calls when the identifier is unique. When it is ambiguous (status 'conflict'), all candidates are listed; a match is never guessed. A bare 'HRB 12345' without the court finds nothing. Example questions (German users): 'Wer steckt hinter DEK1101R.HRB52093?', 'Finde die Firma mit USt-IdNr. DE117663151.', 'HRB 52093 Amtsgericht Köln — was ist das für eine Firma?'

Returns what Overfit offers: products, typical user wishes mapped to the matching tool, documentation URLs, and `planned`, the list of upcoming features (e.g. sign-in and credit from the chat, API keys, tender alerts, data packages) with one value sentence each. Interest in a planned feature is recorded by interesse_melden. Suited to questions what Overfit offers, what is planned, or where the documentation is. No parameters.

Generates a prefilled contact URL and mailto link for the user to send to Overfit. Suited to custom AI projects, company data packages, feedback, or requests not covered by other tools. Nothing is sent: the tool only returns a URL and a mailto link, which the user reviews and opens.
