Comparison · Companyweb

Companyweb alternative

Companyweb is a Belgian business-information platform with an API available on request, and for most of what it does it is broader than we are. This is the honest split, for teams looking up Belgian companies from code.

TL;DR

Companyweb is a Belgian business-information platform. Its site describes company information (a health barometer, a credit limit, financial statements, key figures and payment behaviour), monitoring alerts, prospecting, international search and compliance reports with PEP and sanction checks, and says it processes data from the National Bank of Belgium, the Belgian Official Gazette and the Crossroads Bank for Enterprises daily. It offers standard integrations with CRM, ERP and accounting software and, for custom integrations, a documented API that you reach by contacting Companyweb. Everything on this page about Companyweb was read on its own site (companyweb.be) on 2026-09-30; nothing comes from a third party.

Prometiam is the register-record API. You hand it an enterprise number, a Belgian VAT number or a few typed letters and get the KBO/BCE record back in the same response shape as every other live country. If you need annual accounts, a credit limit, payment behaviour, controlling persons or KYC reports on Belgian companies, Companyweb is the better tool and we are not a substitute. If you need the official record of a Belgian counterparty at a price you can see, starting with a key and no sales conversation, we are the leaner fit.

Where Companyweb is genuinely ahead

1. Breadth of data. Its site lists, for Belgian companies, recent annual accounts and key figures, a health barometer, a credit limit, payment behaviour, the people who control a company with their current and historical mandates, a timeline of events and the official publications for a business, updated daily. The Belgian record on Prometiam is the register record; financial statements are available for Belgian listed companies only (their ESEF annual financial reports; not every report is held).
2. Credit and financial indicators. A credit limit to estimate whether a company can pay your invoices and a health barometer for its long-term health are products on its site. Prometiam serves neither for Belgium.
3. People and networks. Directors, their other companies and their earlier bankruptcies are on its subscription table. Prometiam has no officers for Belgium.
4. Compliance reports. KYC reports that identify possible ultimate beneficial owners, with PEP and sanction checks, sit on its compliance page. Prometiam has no beneficial-owner data for Belgium, and its sanctions screening is beta and a separate endpoint.
5. Monitoring and lists. Alerts on a monitored customer base, including alerts for customers in France and the Netherlands as an extension, prospecting lists, mobile apps and an integration team that helps set up connections. Monitoring on Prometiam is every live country except France and Chile.

Where Prometiam is ahead

1. You can see the price, and start on it. Prometiam publishes every tier: a 14-day trial, then €9.99 to €99.99 a month, monthly or annual, each with its call allowance and rate limit. Companyweb's order page lists subscriptions billed annually with optional add-ons, priced excluding taxes, its integrations page asks you to contact Companyweb for API access, and we did not find an API price on its public pages.
2. The official record, validated. An enterprise number is checked against its mod-97 check digits before you spend a call, and the Belgian VAT number resolves to the same company. Status comes from the register itself, and a company it flags as in dissolution, liquidation, restructuring or bankruptcy is not served as plain active.
3. One schema across the registries. The same response shape for Belgium as for every other country the API covers; adding a market is a country value, not a second integration.
4. Built for a lookup. One bearer key issued at signup, one parameter per identifier, a name search made for a form field, and free lookup tools you can try without a key.
5. No annual commitment. Monthly is the default and neither billing option has a minimum term.

Built for the API-native workflow

Companyweb is built around credit, financial and compliance decisions on Belgian companies. If your workflow is a lookup instead — resolving a customer's identifier, or a few typed letters, into a company record for an onboarding form, an invoice or a CRM row — this is what that looks like on Prometiam:

• Every identifier, one parameter. NIF/CIF for Spain, SIREN or SIRET for France, the company number for the UK, the CRO number for Ireland, the KRS number for Poland, the organisasjonsnummer for Norway, the Y-tunnus for Finland, the organisationsnummer for Sweden, the MBS or the OIB for Croatia, the enterprise number for Belgium, the CVR number for Denmark, the registry code for Estonia, the IČO for Slovakia, the UID for Switzerland, the registration number for Latvia, Cyprus and Romania, the legal entity code for Lithuania, the corporation number for Canada, the ACN or ARBN for Australia, the corporate number for Japan, the company number for Israel, the UEN for Singapore, the NIT for Colombia, the unified business number for Taiwan, the IČO for the Czech Republic, the CNPJ for Brazil, the CUIT for Argentina, the LEI for Germany, the state-prefixed number for the United States (such as NY-4424185) — ?country= picks the register. Prometiam takes the register's 0417.497.106 through company_number, with or without the dots, and the VAT form BE0417497106 through vat=.
• Name search built for a form field. ?name= is a normalised, partial match — call it on every keystroke and wire it into a type-ahead.
• One schema, every registry. The same response shape across ?country=ES|FR|GB|IE|PL|NO|FI|SE|HR|BE|DK|EE|SK|CH|LV|CY|RO|US|LT|CA|AU|JP|IL|SG|CO|TW|BR|CZ|DE|AR|UA|RS|SI|EC|NL|CL|NL|MX.
• Auth and rate limits. A single bearer key (Authorization: Bearer rk_live_...) issued at signup; limits scale 10 to 600 requests/minute by tier.
• A typed client, if you want one. prometiam-risk-api on npm — TypeScript types, retries on 429/5xx, cursor pagination, typed errors. The same client for Python: prometiam-risk-api on PyPI.
• From an agent, not just a form. The MCP server (prometiam-risk-mcp on npm) puts the same lookups in Claude Desktop, Cursor or any MCP client.
• Public pricing, monthly or annual. Every tier is published; paying yearly is ten months' price for twelve. Starter begins with a 14-day trial: 500 credits, 10 requests/minute, card required, nothing charged for 14 days. Subscribing keeps the same key working. The trial is not an ongoing plan.
• Try an identifier before signing up. Free enterprise number (also as a Dutch-language KBO number search), MBS / OIB, organisationsnummer, Y-tunnus, NIF, SIREN, Companies House number, KRS, CRO number and organisasjonsnummer lookup tools run the same call with a shared key.

At a glance

Which to choose

Choose Companyweb if you are a credit, collections or finance team that needs annual accounts, a credit limit, payment behaviour, controlling persons or KYC reports on Belgian companies, want alerts on a monitored customer base and reports for people as well as for code, or want a Belgian vendor with an integration team behind its CRM, ERP and accounting connectors.

Choose Prometiam if you are building onboarding, invoicing or KYB flows that need the official record of a counterparty by enterprise number, VAT number or name, the same response shape across several countries, and a published price you can start on without a sales call.

The two also combine: Companyweb for the wider credit, financial and compliance datasets on Belgian companies, Prometiam for the register record and one schema across the other live countries.

FAQ

Does Companyweb have an API?
Yes. Its integrations page says Companyweb provides a simple, well-documented API with guidelines and test cases, used for example to fill in fields from a VAT number or a company name and to keep customer and supplier records up to date with alerts. Access is by contacting Companyweb.

What does Companyweb cost?
Its order page lists annual subscriptions with optional add-ons, priced excluding taxes, and lists integrations among the add-ons; we did not find an API price on its public pages. Prometiam publishes every tier, starting with a 14-day trial with a card required and nothing charged for 14 days.

Does Prometiam have Belgian financial statements, credit limits or ownership data?
No. Belgium is company-level, with register-change events and monitoring, but no officers, no registry-compliance signal and no insolvency notices (a bankruptcy shows in the company status and in the register-change events). Financial statements are available for Belgian listed companies only (their ESEF annual financial reports; not every report is held). For annual accounts, a credit limit, payment behaviour, controlling persons or KYC reports on Belgian companies, Companyweb is the better tool.

Can I use both?
Yes, and many teams should: Companyweb for the wider credit, financial and compliance datasets, Prometiam for the register record, enterprise number and VAT validation and one schema across the other live countries.
