Lunar API Access — Connect Danish Accounts Fast

Pull live financial data from Lunar (Denmark) into your own app, spreadsheet or accounting stack using a single open-banking.io connection. Instead of scraping screens or wrangling per-bank credentials, you authenticate once and keep Lunar accounts, balances and transactions in sync automatically.

Lunar (BIC LUNADK22XXX) is a Nordic digital-first bank, and open-banking.io speaks its PSD2 interface for you — so a Lunar integration behaves like every other bank on the network.

How to connect Lunar

  1. Create an open-banking.io account and grab your API key.
  2. Call the endpoint for Lunar to start an authorization session.
  3. Have the account holder approve access in Lunar's own app.
  4. Receive your access token and begin fetching data right away.

What data you can access

  • Accounts — personal and business account details and identifiers
  • Balances — up-to-date available and booked amounts
  • Transactions — historical and incoming entries with counterparties, dates and amounts

Lunar supports both personal and business account types, so the same integration covers freelancers, companies and everyday customers.

A single user approval stays valid for up to 180 days before it needs renewal — one of the longest windows PSD2 permits. Lunar is just one endpoint among 2,600+ banks reachable through the same API, so extending to other institutions across the EU and UK means no new integration work.

Privacy by design

open-banking.io is zero-knowledge: your customers' banking data flows through to you, not into a data warehouse we mine. There are no eIDAS certificates to buy, register or rotate — we handle the regulated plumbing so you skip the compliance overhead entirely.

Pricing

Access starts at roughly EUR 3 per month, with no per-call surprises. That flat, low cost makes it practical to build against Lunar whether you run one connection or thousands.

FAQ

Do I need my own PSD2 licence to access Lunar?

No. open-banking.io operates as the licensed intermediary, so you connect to Lunar without holding your own regulatory permissions or certificates.

How often can I refresh Lunar data?

As often as your use case needs within the active consent. Each authorization lasts up to 180 days, after which the account holder simply re-approves.

Can I read both personal and business Lunar accounts?

Yes. Both account types are supported through the same API, so mixed portfolios work without extra configuration.
