Kruispuntdatabank API is a Belgium-focused business data lookup service for developers. Its core purpose is to expose company information from the Kruispuntbank van Ondernemingen (KBO) through a JSON REST API for use in websites and applications. Typical use cases include validating company numbers in forms, auto-completing company names, populating CRM or administrative software with business profiles, and validating VAT numbers for cross-border transactions within the EU.
Based on the documentation, the API offers a fairly comprehensive set of endpoints: company details, business activities, addresses, trade names, branches, brief financial information, NSSO, official functions/roles, legal forms and legal status, NACE codes, company name search, address search, VAT validation, as well as Webhook subscriptions and event logs. The API uses Bearer token authentication, provides both production and sandbox environments, and returns request usage and quota information in response headers, which is useful for quota monitoring. The documentation supports Swagger UI, Postman import, and cURL examples. Since it uses a REST/JSON format, it can be integrated with any language capable of sending HTTP requests.
The service uses a subscription model, with Small, Medium, and Large plans providing 2,500, 10,000, and 30,000 requests per month respectively. The page emphasizes fixed pricing and avoiding unexpected charges, but the captured text does not show specific euro prices. Note that some endpoints are plan-restricted; for example, company contact information is marked as “Large plan or up.” Therefore, when choosing a plan, you should not only compare request volume but also verify whether the required fields are included.
The strengths are a clear data model, granular endpoints, and documentation that covers authentication, pagination, status codes, sample responses, and environment details. It also provides developer-friendly features such as a sandbox, Swagger, and Postman support. The page additionally discloses metrics such as 1000+ users, 215,000 daily requests, 30ms average response time, and 99.99% uptime. The downsides are that the service is tightly tied to the Belgian KBO use case and is not suitable for unified multi-country company data lookup; the documentation is English-only; there are no apparent open-source, self-hosted, or on-premise deployment options; and the actual pricing amounts are not transparent.
It is suitable for SaaS, ERP, CRM, finance, logistics, and e-commerce systems that have customers, suppliers, merchant onboarding, or compliance verification needs in Belgium. Chinese teams serving the European or Belgian market can use it as a component for business master data and VAT validation. The source text does not provide information about access from mainland China. Payment methods include bank cards, PayPal, Bancontact, iDeal, and others; whether they work well for China-based entities should be confirmed in practice.
