Billing — subscriptions, prepaid credits, invoices
How Apier billing works — the two payment methods (subscription tiers and prepaid credits), the quota-first spend order, invoices and receipts via Stripe, VAT (MVA), and how to change or cancel.

During the beta, all usage is free — nothing is charged. This guide describes how billing works when it goes live, so you can plan for it. For the machine-first payment loop an autonomous agent implements (price discovery, the 402 recovery contract, top-up handover, retry), see the agent payments guide. For the tier matrix and figures, see /pricing.
Two ways to pay
When billing goes live you can pay in either of two ways — or both:
- Monthly subscription. A fixed monthly fee that bundles a set number of API calls. The tiers, their included call quotas, and the bundled solutions are on /pricing.
- Prepaid credits. A balance you top up in advance; each metered call draws its cost from it (50 øre — NOK 0.50 — for a company-data read). Top-ups run from NOK 50 to NOK 10,000 per transaction, and unused credits stay on your account.
Which is spent first
If your account holds both a subscription and prepaid credits, your subscription's included calls are consumed first; credits are only drawn once those included calls run out. Unused credits are never forfeited — they stay on the account for later. This quota-first ordering is enforced from billing go-live; during the beta every call is free, so nothing is spent in either bucket.
Invoices and receipts
Payments — subscription charges and credit top-ups alike — are processed by Stripe. Invoices and payment receipts are available in the billing portal at /dashboard/billing, the same place you top up a prepaid balance. Apier never stores your card details; they are held by Stripe.
VAT (MVA)
All prices are stated exclusive of Norwegian value-added tax. VAT (merverdiavgift, MVA) is added where applicable and itemised on the Stripe invoice. In short: all prices exclude VAT (MVA).
How to change or cancel
Subscriptions can be changed or cancelled anytime from the billing portal at /dashboard/billing. Changes take effect at the end of the current billing period — you keep access to the plan you have paid for until then. Cancelling a subscription does not remove any prepaid credits: an unused credit balance remains available afterward.
Agent payments — discover prices, survive 402, top up, retry
The full prepaid-credit payment loop for autonomous agents — price discovery at /api/v1/pricing, the machine-readable 402 recovery contract, the human top-up handover, and balance visibility on every metered response.
Inspecting actions with the audit trail
Agents have no dashboard. Use the signed receipt, the audit endpoint, correlation_id, and initiated_by to reconstruct exactly what an action did — on the sandbox today, on production later.
