Pricing
Metered per call against a monthly allowance, with a free tier that needs no card. Paid plans bill overage rather than cutting you off, so a spike in traffic is an invoice line and not an incident.
Plans
| Plan | Per month | Calls included | Suits |
|---|---|---|---|
| Free | Free | 5.000 | Trying it out, side projects, a proof of concept. |
| Starter | 99 DKK | 100.000 | A single production integration — one checkout, one CRM sync. |
| Pro | 249 DKK | 500.000 | A product with real traffic, or several integrations at once. |
| Scale | 599 DKK | 2.000.000 | High-volume batch work, enrichment pipelines, bulk exports. |
| Enterprise | Annual | Uncapped | Volume, support commitments and procurement requirements. |
Paying annually is 20% below twelve months at the monthly rate on Starter, Pro and Scale. Prices exclude VAT.
What is metered
One request to a /v1 endpoint, or one MCP tool call — both draw on the same allowance. A gf_test_ key runs against the sandbox and is never metered or billed, so you can build the whole integration before choosing a plan.
Start on the free tier
No card. Create a key, make a call, and upgrade only when the volume asks for it.

Frequently asked questions
What counts as a call?
One request to a /v1 endpoint, or one MCP tool invocation. They are metered identically and draw on the same monthly allowance. Test keys (gf_test_) are never metered or billed.
What happens if I go over the allowance?
On a paid plan, additional calls are charged as overage rather than cut off, so a traffic spike does not break your integration. The Free tier is hard-capped instead — it stops rather than generating a bill you did not agree to.
Is there an annual option?
Yes. Paying for a year up front is 20% below twelve months at the monthly rate, on Starter, Pro and Scale.
Do you have an Enterprise plan?
Yes — an annual contract for higher volume, support commitments and procurement requirements that self-serve billing cannot cover. It is quoted rather than listed.
Is the underlying data free?
The register data originates from Datafordeler / SDFI and is licensed CC BY 4.0, and Grundfast credits the source. What you pay for is the transformation, the caching, the availability and the support — not the data itself. You can always go to the source directly.
Can I try it without a card?
Yes. The Free tier needs no card, and a gf_test_ key gives you a sandbox that is never billed, so you can build the whole integration before deciding on a plan.
