How it works
The Internet Speed Check API connects you to KPN's network information. This gives you access to the technically available maximum bandwidth and carrier types for any address. Please note that the highest internet speeds for an address might only be available through specific providers.
The API needs little input: postal code, house number and, if applicable, house number extension. If the address is not known by the back-end or is somehow incorrect or incomplete, this API will respond with an alert that allows you to review and correct your input.
Retrieve possible internet speeds with just a postal code and a house number.
Get to know the maximum possible bandwidth at any address in the Netherlands.
