Datenbank der Unternehmen API is a Belgium-focused business data REST API for developers, operated by FaimMedia BV. It clearly states that it is not a Belgian government agency. The service wraps information related to KBO/ZDU, Belgium’s central enterprise database, into a JSON API, making it easier to integrate company lookup and validation into websites, accounting systems, administrative software, and relationship management applications.
Its feature coverage is fairly comprehensive. You can query company details, business units, business activities, addresses, contact information, names, legal forms, legal status, brief financial information, NSSO data, and roles/functions. It also supports company-name autocomplete, address search, NACE code lookup, and VAT number validation. The webhook functionality is also relatively systematic, covering creation, updates, deletion, subscriptions, event logs, HMAC secrets, and manual triggering, making it suitable for systems that need to monitor changes to business entities.
The API uses a JSON REST architecture with Bearer Token authentication, and provides both production and Sandbox environments. The documentation quality is good, covering API/REST basics, authentication, pagination, response headers, rate-limit information, endpoint overviews, request parameters, response fields, HTTP status codes, cURL examples, as well as Swagger UI and Postman import support. The documentation also notes that any language capable of handling HTTP requests can use the API, and that some returned field descriptions support Dutch, English, French, and German.
The product uses fixed-price subscriptions, which makes costs predictable. Plans include Small, Medium, and Large, with monthly request limits of up to 2,500, 10,000, and 30,000 respectively. Some endpoints and features depend on the purchased plan. Plans can be upgraded, while downgrades take effect in the next billing cycle. The maximum subscription term is currently one year, and automatic renewal is not yet supported. Unfortunately, the captured text does not include specific price amounts.
Its strengths include rich data coverage, a low integration barrier via REST, solid documentation and testing tools, and disclosed usage metrics such as 99.99% uptime and 215,000 requests per day. The downsides are that its coverage is clearly focused on Belgian companies, making it unsuitable for global business database needs; plan features are restricted; and pricing details are missing. It is a good fit for teams that need to verify Belgian company numbers, VAT details, and address information during registration, KYC/company-profile enrichment, or within CRM, ERP, finance, or administrative systems.
The text does not provide information about access from mainland China, network connectivity, or local payment options, so its accessibility from China should be considered unknown. Payment methods include Bancontact, iDeal/Wero, bank cards, and PayPal, processed by Mollie. Teams in China should independently confirm cross-border payment availability and API connectivity.
