How to choose a Danish license plate API
Several providers sell lookups in Danish vehicle data. They build on the same public sources but differ in price, freshness and how easy they are to build on. Here is what to check.
What to check
-
1. Data source and freshness
Where does the data come from, and how old is it? Motorbay builds on Motorstyrelsen's weekly extract and says in every response which extract you get (the Motorbay-Data-As-Of header).
-
2. Price at your usage
Work out the price at your expected lookups per month, not only the starting price. Motorbay's price calculator does it for every plan.
-
3. Which fields you get
Motorbay serves the register's technical data: engine, environment, fuels, weights, the latest inspection and equipment. The data page shows every field, so you can see that it covers what you need before you sign up.
-
4. Developer experience
Is there an OpenAPI file, stable error codes, versioning and a dated changelog? Motorbay has all four.
-
5. Operations and openness
Is there a public status page, and can you see how old the data is? Motorbay has status at status.motorbay.app, and every response says which extract it comes from.
-
6. Commitment and free use
Can you try the API without a card and cancel when you want? Motorbay has a free plan with no card and no commitment on the paid plans.
Motorbay is a good fit when
- you need to look up Danish vehicles by plate, VIN or ID from your own code.
- you need the register's technical data, the latest inspection and equipment.
- you want a set monthly price with requests included, and to cancel when you want.
