# Querying Polish public tenders

Przetargowy Janusz aggregates Polish public procurement notices (`przetargi`)
from many source platforms into one searchable catalogue.

## Ways in

- **MCP server** (structured, recommended for agents): see the `mcp-tenders`
  skill. Endpoint `https://przetargowyjanusz.pl/mcp`.
- **Public pages**: `/przetargi` (browse), `/przetargi/branza/{cpv-slug}`,
  `/przetargi/wojewodztwo/{region-slug}`, `/przetargi/miasto/{city-slug}`, and
  `/przetargi/{slug}` for one tender.
- **Markdown for agents**: request any public content URL with
  `Accept: text/markdown` to get a clean Markdown rendering at the same URL.
- `https://przetargowyjanusz.pl/llms.txt` describes the machine-readable surface.

## Domain terms

- **CPV** — Common Procurement Vocabulary; an 8+1 digit code (e.g. `45000000-7`)
  classifying what is procured. The first 2 digits are the "division".
- **SWZ** — Specyfikacja Warunków Zamówienia (tender specification document).
- **OPZ** — Opis Przedmiotu Zamówienia (description of the subject of the order).
- **Zamawiający** — the contracting authority (buyer).
- **Termin składania** — the submission deadline.

## Notes

- Only tenders with a generated AI summary are exposed publicly.
- Values are in PLN unless a tender states otherwise.
- Data is read-only; there is no public write/registration API yet.
