api record

skanfirmy.pl: verify Polish companies by NIP/KRS and validate EU VAT numbers (VIES), straight from official government registers (Ministry of Finance, Ministry of Justice, Statistics Poland/GUS, EU VIES). Also includes szukaj_katalog_api, which searches otwarteAPI.pl, a catalog of other public Polish and EU APIs. The verification tools are free and need no auth. The monitoring tools (observe_nip, unobserve_nip, list_observations, changes_since, set_webhook) require a skanfirmy API key: pass it in the Authorization: Bearer <key> header or the api_key argument. You get a key after confirming…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_observations auth-required 2h ago

    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.

  • szukaj_katalog_api unknown never probed

    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 unknown never probed

    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.

  • sprawdz_nip unknown never probed

    Check VAT status (VAT White List / Biała Lista) and KRS data for a Polish company by NIP. For entities without a KRS number (sole proprietors and civil partnerships, i.e. natural persons) personal data is limited (GDPR): the address is reduced to the town (the White List does not say whether it is a business or a home address), and bank accounts to their count — check a specific account with sprawdz_rachunek. The privacy field lists what was hidden.

    arguments 12 lines
  • sprawdz_lista_nip unknown never probed

    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 entities without a KRS number (natural persons) the address is reduced to the town and bank accounts to their count (GDPR) — check a specific account with sprawdz_rachunek. 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).

For natural persons (GUS type F / LF) and civil partnerships (s.c.) the address is limited to the town and administrative units, without street, number or postal code (GDPR).

  • sprawdz_vies unknown never probed

  • generuj_mikrorachunek unknown never probed

    Generate the individual tax micro-account (for PIT/CIT/VAT payments) from a NIP.

  • changes_since unknown never probed

    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. For natural persons (entities without a KRS number; natural_person: true) account numbers are masked (check digits + last 4, e.g. 61…2874) and the address is reduced to the town (GDPR); check a specific account with sprawdz_rachunek. A polling channel for agents. Requires a skanfirmy API key.

  • set_webhook unknown never probed

    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).

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/2e297f7af61dab1b/badge.svg)](https://brick.blue/agent/2e297f7af61dab1b)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
