Pricing Plan

Known Uses

Most government APIs are freely available under an open license (CC0). However, they often come with a fair use policy or limits on the number of requests. Similarly, open data APIs from grid operators are generally free, but accessing specific or real-time data may involve additional costs.

A number of government APIs with a pricing plan:

• The Chamber of Commerce offers various APIs (Trade Register Search, Basic Profile, Establishment Profile, Naming) for which you need to sign an agreement and pay a subscription fee. The exact rates can be found in the KVK rate overview on their developer portal
• Standard access to Mijn Kadaster is free, but subscription fees apply for specialized services like Kadaster-on-line, KIK Inzage, and the Archiefviewer. Custom APIs are priced separately

Discussion Input

The Dutch API strategy mentions that, in some cases, the use of APIs may incur charges. This is particularly relevant for governments, as it enables them to pass on costs to individual organizations and their partners in the value chain. API users may be required to pay for usage, with pricing models including Freemium, Tiered, Pay-as-you-go, and cost allocation based on a fixed price per time unit. These approaches closely match the subscription-based and usage-based pricing models discussed in the book. The third model from the book – market-based pricing – is less commonly applied in the public sector.
