Monitoruj zmiany

Wyłapuj nowe wpisy w rejestrze i otrzymuj powiadomienia.

Drogi w porównaniu

Droga
Droga Dobra do Potrzebujesz Koszty

Signals Zmiany we wszystkich firmach według tematu i okresu albo celowo dla maksymalnie 5 firm Regularne zapytania przez API 20 kredytów za stronę
Monitoring Wybrane firmy; sprawdzamy według stałego harmonogramu i powiadamiamy przez webhook Publicznie dostępny endpoint HTTPS Jedna cena cyklu za monitor na 30 dni
Watchlista Śledzenie bez własnego serwera, w przeglądarce lub czytniku feedów Tylko aplikacja webowa 20 kredytów za aktualizację feedu, najwyżej raz na godzinę

Każdy przebieg kosztuje do 7 kredytów za firmę: dane podstawowe i zarząd, ten drugi tylko gdy API znajdzie osoby. Przy wielu firmach lub krótkich odstępach Signals albo Monitoring są tańsze.

200 · Przykładowa odpowiedź: zmiany kapitału ogłoszone od 26 do 30 października 2026 (fragment)

Strona zawiera do 20 Signals, najnowsze najpierw, i kosztuje 20 kredytów. Jeśli jest ich więcej, pagination.next_cursor zawiera wskaźnik na następną stronę. Przekaż go z powrotem jako cursor z tymi samymi filtrami.

from i to odnoszą się do daty ogłoszenia (announced_on). Samo zdarzenie (occurred_on) może być wcześniejsze, np. uchwała o połączeniu.

Dla konkretnych firm przekaż do 5 entity_id w organization_ids. Przy codziennej synchronizacji pytaj o ostatnie kilka dni i przechodź dalej, aż has_more będzie false.

Sygnał może pojawić się nieco później niż jego ogłoszenie i wystąpić na kilku stronach. Pytaj więc o nakładające się okresy i usuwaj duplikaty po event.id.

Obserwuj pojedyncze firmy z Monitoring

Monitor sprawdza firmę pod kątem nowych Signals co 1 do 30 dni. Każdy nowy sygnał wysyłamy jako podpisany webhook do twojego endpointu webhooka. Tak to skonfigurujesz:

  1. Utwórz endpoint webhooka: w aplikacji webowej w Monitoring albo przez API przez POST /v1/account/webhook-endpoints z polami name i url (tylko HTTPS). To zapytanie wymaga tokenu admina z Konto › Klucze API w nagłówku Authorization: Bearer …. Klucz API tu nie wystarcza. Odpowiedź zawiera id endpointu (wep_…) i secret do podpisów, który pokazujemy tylko raz.
  2. Zweryfikuj endpoint przez POST /v1/account/webhook-endpoints/{id}/verify. Wysyłamy wtedy wiadomość typu endpoint.verification. Twój endpoint odpowiada w ciągu 15 sekund kodem 2xx i zwraca data.challenge w nagłówku webhook-verification. Dopiero wtedy otrzymuje dostarczenia.
  3. Utwórz monitor, z entity_id, poll_interval_days i id z kroku 1 w endpoint_ids.

    "endpoint_ids": ["wep_TWOJE_ENDPOINT_ID"]
  }'

Zapytania zapisujące do monitorów wymagają Idempotency-Key. Jeśli powtórzysz je z tym samym kluczem, drugi monitor nie powstanie.

Utworzenie monitora jest bezpłatne. Najpierw monitor oznacza Signals z ostatnich kilku dni jako znane, bez ich wysyłania. Potem nalicza cenę pierwszego cyklu 30 dni i od razu wykonuje pierwsze sprawdzenie.

Monitor sprawdzany codziennie, przez 30 dni 50
Monitor sprawdzany co 3 dni, przez 30 dni 40
Monitor sprawdzany co 7 dni, przez 30 dni 20
Monitor sprawdzany co 30 dni, przez 30 dni 10

Wstrzymywanie, wznawianie, zmianę harmonogramu i usuwanie opisuje account/monitors.

Odbieraj i weryfikuj webhooki

Każde dostarczenie to POST z JSON-em. Przy weryfikacji wysyłamy wiadomość z type endpoint.verification. Odpowiedz kodem 2xx i ustaw nagłówek webhook-verification na wartość z data.challenge. Dla nowego sygnału type to organization.signal.detected, a data.signal ma ten sam format co wpis z signals.

Każde dostarczenie zawiera trzy nagłówki:

Pole
Pole Znaczenie
webhook-id Identyfikator wiadomości, ten sam przy ponowieniach. Użyj go do wykrywania duplikatów.
webhook-timestamp Czas tej próby dostarczenia w sekundach Unix.
webhook-signature Jeden lub więcej podpisów w formie v1,…, rozdzielonych spacjami.

Podpis jest zgodny z otwartym standardem „Standard Webhooks”: HMAC-SHA256 z webhook-id.webhook-timestamp.body. Kluczem jest część secretu po whsec_, zdekodowana z Base64. Sprawdź podpis na niezmienionym body, zanim je przetworzysz. 

import base64
import hashlib
import hmac
import time


def verify_webhook(secret: str, headers: dict, body: bytes) -> bool:
    """Sprawdza podpis dostarczenia od handelsregister.ai."""
    msg_id = headers["webhook-id"]
    timestamp = headers["webhook-timestamp"]
    if abs(time.time() - int(timestamp)) > 5 * 60:
        return False  # starsza lub nowsza niż pięć minut
    key = base64.b64decode(secret.removeprefix("whsec_"))
    signed = f"{msg_id}.{timestamp}.".encode() + body
    expected = base64.b64encode(hmac.new(key, signed, hashlib.sha256).digest()).decode()
    for candidate in headers["webhook-signature"].split(" "):
        version, _, signature = candidate.partition(",")
        if version == "v1" and hmac.compare_digest(signature, expected):
            return True
    return False

Odpowiedz w ciągu 15 sekund kodem 2xx i przetwarzaj potem. Bez 2xx ponawiamy dostarczenie w rosnących odstępach przez około trzy dni. Po rotacji secretu wiadomości przez siedem dni mają oba podpisy.

Dostarczenia, ponowienia i wszystkie pola opisuje account/webhook-endpoints.

Watchlista i feedy

Watchlista to droga bez własnego serwera. W aplikacji webowej w Monitoring obserwujesz firmę jednym kliknięciem. Bez monitora możesz obserwować do 15 firm. Firmy z monitorem są na watchliście automatycznie.

Watchlista pokazuje Signals twoich firm z ostatnich dwunastu miesięcy, najnowsze najpierw. Przez „Wygeneruj URL feedu” dostajesz je jako feed RSS lub Atom dla dowolnego czytnika.

Feed aktualizuje się najwyżej raz na godzinę, niezależnie od tego, jak często pobiera go czytnik. Każda aktualizacja kosztuje 20 kredytów. Jeśli saldo nie wystarcza, feed pokazuje ostatni stan i aktualizuje się znowu, gdy tylko masz kredyty.

URL zawiera tajny klucz i jest pokazywany tylko raz. Jeśli go odnowisz, stary natychmiast przestaje działać. Z ?lang=en feed przychodzi po angielsku.

Te same dane dostajesz przez API z Signals z organization_ids.
