Список инструментов сервера (14)
Технические названия из tools/list. Нужны только разработчикам.
| sprawdz_nip | Check VAT status (VAT White List / Biała Lista) and KRS data for a Polish company by NIP. |
| sprawdz_lista_nip | Bulk-check up to 30 NIPs in one call to the Ministry of Finance VAT White List: VAT status, bank accounts, REGON, KRS and address of each entity. For verifying a portfolio of counterparties. Ministry limits: max 30 NIPs per call, about 500 bulk queries/day per IP. Does not fetch full KRS data (use sprawdz_nip for individual entities). |
| sprawdz_regon | Look up entity data in the REGON register (Statistics Poland / GUS BIR) by NIP: REGON number, official name, legal form (legal or natural person), full address (voivodeship, county, municipality). Covers ALL entities, including sole proprietors that are not in the KRS. |
| sprawdz_vies | Validate a counterparty's EU VAT number in the VIES system (European Commission). |
| sprawdz_rachunek | Check whether a bank account number (NRB) appears in the VAT White List for a given NIP. Due diligence for payments above PLN 15,000. |
| generuj_mikrorachunek | Generate the individual tax micro-account (for PIT/CIT/VAT payments) from a NIP or PESEL. |
| szukaj_pkd | Search PKD 2025 business activity codes by activity name or code number. |
| oblicz_odsetki | Calculate statutory or commercial (B2B) late-payment interest, broken down by NBP reference-rate periods. |
| szukaj_katalog_api | Search otwarteAPI.pl, a catalog of public Polish and EU APIs (VAT, KRS, GUS, NBP, ECB, Eurostat and more). Returns matching entries with a link to each API's official docs. An empty query returns the whole catalog (optionally narrowed by scope or topic). |
| observe_nip | Add a NIP to monitoring. You get notified (via changes_since or email) when its VAT status, bank account, or registry data shown on the Ministry of Finance White List (name, address, KRS, REGON) changes. Requires a skanfirmy API key (Authorization: Bearer, or the api_key argument). Free plan: up to 10 NIPs. |
| unobserve_nip | Remove a NIP from monitoring. Requires a skanfirmy API key. |
| list_observations | Return the list of NIPs you monitor, with their current VAT status and last-checked date. Each entry keeps the raw Ministry of Finance literal in status_vat and, when a status is known, adds derived language-neutral fields vat_active (boolean) and status_vat_code (active/exempt/not_registered). Requires a skanfirmy API key. |
| changes_since | Return changes (VAT status, bank accounts, or registry data — name, address, KRS, REGON — from the White List) detected since a given date for the NIPs you monitor. The field property is one of: status_vat, account_added, account_removed, name, address, krs, regon. A polling channel for agents. Requires a skanfirmy API key. |
| set_webhook | Set (or clear) a push webhook URL for your monitoring, instead of or in addition to polling. When we detect a change for a monitored NIP, we send a POST signed with HMAC-SHA256 (X-Skanfirmy-Signature header). Returns the secret ONCE. Pass an empty url to disable. Requires a skanfirmy API key. Public https addresses only (port 443). |
