Nykredit Exchange Rate API: DKK Buy and Sell Rates as JSON

Nykredit is a Danish mortgage lender and bank. Its listing-rate page gives DKK rates per 100 units for 22 currencies, used for payments to and from abroad and currency-account transfers, with the reference rate and Nykredit's margin. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Danmarks Nationalbank official rate and with other banks in Denmark, and the calls that return them.

What the Nykredit board shows

• 22 currencies against the Danish krone: AED, AUD, CAD, CHF, CNY, CZK, EUR, GBP, HKD, HUF, JPY, MXN, NOK, NZD, PLN, RON, SEK, SGD, THB, TRY, USD and ZAR. Every value is DKK per 1 unit of the foreign currency.
• The listing rates (noteringskurser) for payments and account transfers, buy / sell pair. Danish banks quote the price in kroner of 100 units of foreign currency and set separate rates for payments from abroad, payments to abroad and cash. The pair here is the transfer board; Danmarks Nationalbank publishes one reference rate per business day. The Danmarks Nationalbank official rate is shown next to each row.
• USD on 15 November 2026: Nykredit bought at 6.7398 and sold at 6.7898 DKK, a spread of 0.74%. The Danmarks Nationalbank official rate was 6.764, so the bank's mid sat +0.01% from it.
• The bank's own timestamp. The page prints a last-updated stamp (2026-11-13 on the board above), returned as bank_updated_at next to our captured_at.
• Every day's board is kept permanently, from 13 November 2026. Read one past day with ?date=, or a range for one currency with the /history endpoint (paid plans).

Spreads across the board

On the 15 November 2026 board the tightest spreads were CHF (0.62%), AUD (0.65%), NOK (0.68%) and the widest TRY (3.72%), HKD (2.32%), AED (2.28%). Spread is (sell − buy) ÷ mid: what a round trip through the bank costs, before any fees. The API returns it on every row as spread_pct, so you can rank currencies or alert when a bank widens its board.

Board rate or official rate?

The Danmarks Nationalbank rate is the one tax, accounting and customs rules in Denmark name; nobody transacts at it. Nykredit's board is the price a customer actually gets. The API puts both on every row: official is the central bank's rate for the same currency and vs_official_pct is how far the bank's mid sits from it. Use the board to show customers a real price, compare banks for a remittance, or keep a dated record of what the bank quoted; use the Danmarks Nationalbank endpoint when a rule asks for the official rate.

FAQ

Where do the Nykredit rates come from?

From the bank's own public rates page (https://www.nykredit.dk/dit-liv/valutakurser/noteringskurser/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Nykredit shows, with the mid, the spread and the Danmarks Nationalbank rate added.

Are these the official DKK exchange rates?

No. They are Nykredit's retail prices for customers. The official rate in Denmark is the Danmarks Nationalbank rate, which the API returns as official on each row where the central bank has one, and in full from the central-bank endpoint.

How often is the Nykredit board updated?

AllRatesToday reads the page every hour. The bank's own last-updated stamp is returned as bank_updated_at, so you can tell a fresh read of an unchanged board from a new board.

Can I get Nykredit rates for a past date?

Yes, from 13 November 2026 onward; every day's board is kept permanently. Add ?date=YYYY-MM-DD for one day: the response is the board captured that day, or the nearest earlier day within five days, with date_requested and snapshot_date added. For a range, /history?ccy=USD&from=…&to=… returns one row per day as JSON, CSV, XML or XLSX on paid plans.

Do I need an API key?

Yes. Commercial bank boards need an API key; any plan works, the free key included, and each call counts against the plan. Public pages or widgets that show the rates need a visible link to allratestoday.com.
