BIG InfoMonitor alternative: the KRS company record via API, not a debtor register

BIG InfoMonitor tells you whether a Polish company or consumer already has unpaid debts on record. Prometiam answers a different question — whether the company legally exists — as a REST API across all live countries, and holds no payment-default data of its own.

BIG InfoMonitor figures read from big.pl and bik.pl on 16 September 2026

TL;DR

BIG InfoMonitor, part of the BIK group, runs Poland's shared debtor registry and sells payment-credibility reports on companies and consumers: contractor verification with a recommendation, a full BIK credit history for your own company, an invoice payment-reminder tool (Bezpieczna Faktura BIK), a formal payment demand, and an entry in the debtor registry — bundled through a business account from PLN 189 net per six months, with no self-serve API found on its public pages. Prometiam is a REST API for the official Polish KRS company record, alongside more European registries, updated daily, with monitoring webhooks and sanctions screening (beta) on the same key — and no payment-default data at all, so it is often used alongside a debtor register rather than instead of one.

Who should pick BIG InfoMonitor

• You need to check whether a Polish company or consumer already has unpaid debts on record, through the shared BIG InfoMonitor debtor registry.
• A contractor hasn't paid you: BIG InfoMonitor lets you send a formal wezwanie do zapłaty (payment demand) and then enter them in the debtor registry to press for repayment — something Prometiam does not offer.
• You want Raport BIK Moja Firma — your own company's full BIK credit history plus its debtor-registry status — in one account.
• You check both companies and individual consumers, and want the BIK group's combined bank-credit and debtor-registry view rather than a company-registry-only source.

Who should pick Prometiam

• You verify that a Polish company legally exists — the KRS record — programmatically, as one step of an onboarding flow, not through a business-account portal. The free KRS, NIP and REGON search (in Polish) shows the record.
• Your counterparties span more than Poland: every other country the API covers sits behind the same key and the same response shape (see the Poland KYB API guide for the exact field list).
• You run ongoing supplier due diligence and want a signed webhook when a Polish company's status changes, via POST /monitor.
• You want to test before paying: a free trial of 500 credits over 14 days with a card required and nothing charged for 14 days, then published prices with no contract.

Scope limits, stated plainly

• Poland on Prometiam is company-level: no officers, no CRBR beneficial-ownership register, no KRZ insolvency feed.
• Prometiam holds no payment-default, debtor-registry or credit-history data of any kind — that is BIG InfoMonitor's core product, not Prometiam's.
• Sanctions screening is beta; monitoring (POST /monitor) covers every live country except France and Chile; PEP screening is beta and Spain only.
• Beneficial ownership on Prometiam is the UK PSC register only; GLEIF Level-2 adds parents for entities that hold an LEI. The compliance deadlines behind Polish KYB demand are in the KYB for Poland under MiCA & AMLR (2026) guide.

Beyond the registry record

Two derived signals, neither of them a rating. Both are dated facts carrying the source they came from, so whoever reviews your file can check them.

• Companies that stopped filing. A company that quietly stops trading rarely dissolves; the register notices first. The registry_compliance flag returns that state in one shape for Spain (provisional closure of the registry sheet), the United Kingdom (a strike-off proposal, or annual accounts overdue), Ireland (the strike-off list) and Norway (compulsory liquidation). Read it on GET /companies/{id}?include=risk_flags, or list those companies with risk_flag_type=registry_compliance. It is a compliance signal, not an insolvency: read it together with status.
• Public contracts, and the buyer behind them. GET /procurement/awards returns public-contract awards from Spain, France, the UK, Ireland, Poland and Norway by supplier, buyer, identifier, CPV code and date, linked to the supplier’s registry record where the identifier resolves. GET /procurement/buyer/{id} scores the contracting body itself: the probability that its next award draws a single bid, and the probability that a supplier it awards to enters insolvency within two years.

Both are ordinary REST calls on the published price and included in the 14-day trial. Procurement awards cover Spain, France, the UK, Ireland, Poland and Norway (Ireland, Poland and Norway above the EU thresholds only), the buyer scores are Spain and France and in beta, and a score is a prompt to look, never a finding of wrongdoing.

FAQ

Does Prometiam have payment-default or debtor data like BIG InfoMonitor?
No. Prometiam returns the official KRS company record — legal name, KRS number, NIP, REGON, legal form, PKD activity code, registered address and share capital — not payment history, debtor-registry entries or credit history. It answers whether a company exists and is active, not whether it pays on time.

How much does BIG InfoMonitor cost?
As published on big.pl/firma on 16 September 2026, the BIK-for-business bundle (Raport BIK Moja Firma, Raport Weryfikacja Kontrahenta, Bezpieczna Faktura BIK and one debtor-registry entry) starts at PLN 189 net per six months. Pricing for higher volumes or system integration is not published; BIG InfoMonitor directs those requests to duzefirmy@big.pl.

Does BIG InfoMonitor have a public API?
No self-serve API or developer page was found on big.pl or bik.pl as of 16 September 2026. Access is through a BIK business account, and larger clients are told to contact BIG InfoMonitor directly about integration. Prometiam is a REST API from the first call: one key, an OpenAPI spec, and an MCP server for AI agents.

Can I use BIG InfoMonitor and Prometiam together?
Yes. Teams commonly use BIG InfoMonitor's debtor registry and credit-history reports to see whether a Polish counterparty has already defaulted, and Prometiam's KRS record and monitoring webhook to confirm the company exists, watch its status, and screen its name against sanctions lists (beta) as part of the same onboarding flow.

Which countries does each cover?
BIG InfoMonitor's debtor-registry and credit-history products cover Poland, through the BIK group. Prometiam covers official company registries under one key — Spain, France, the UK, Ireland, Poland, Norway, Finland, Sweden, Croatia, Belgium, Denmark, Estonia, Slovakia, Switzerland, Latvia, Cyprus, Romania, Lithuania, Canada, Australia, Japan, Israel, Singapore, Colombia, Taiwan, Czech Republic, Germany, Argentina, Ukraine, Serbia, Ecuador, Chile, Mexico, the Netherlands, Brazil and the United States — with Poland at company level: no officers, no CRBR beneficial ownership, no KRZ insolvency feed yet.
