NLB Banka Banja Luka Exchange Rate API: BAM Buy and Sell Rates as JSON

NLB Banka a.d. Banja Luka is the NLB Group’s bank in Republika Srpska. Its kursna lista gives non-cash and cash buying and selling rates in convertible marks for 11 currencies. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Central Bank of Bosnia and Herzegovina official rate and with other banks in Bosnia and Herzegovina, and the calls that return them.

What the NLB Banja Luka board shows

• 11 currencies against the Bosnia and Herzegovina convertible mark: AUD, CAD, CHF, DKK, EUR, GBP, JPY, NOK, RSD, SEK and USD. Every value is BAM per 1 unit of the foreign currency.
• The non-cash (devizni) buy / sell pair. The convertible mark is pegged to the euro at 1.95583 under a currency board, so banks quote the euro at or very near that rate and set wider buying and selling rates for other currencies. Banks publish one list for account (non-cash) transactions and another for cash. The Central Bank of Bosnia and Herzegovina official rate is shown next to each row.
• USD on 15 November 2026: NLB Banja Luka bought at 1.7167 and sold at 1.8229 BAM, a spread of 6.00%. The Central Bank of Bosnia and Herzegovina official rate was 1.7694, so the bank's mid sat +0.02% from it.
• No timestamp on the bank's page. NLB Banja Luka does not print a last-updated time, so bank_updated_at is null and captured_at (when AllRatesToday read the page) is the only time available.
• Every day's board is kept permanently, from 14 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 EUR (0.00%), DKK (5.50%), CHF (5.74%) and the widest RSD (8.00%), NOK (7.00%), JPY (7.00%). 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 Central Bank of Bosnia and Herzegovina rate is the one tax, accounting and customs rules in Bosnia and Herzegovina name; nobody transacts at it. NLB Banja Luka'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 Central Bank of Bosnia and Herzegovina endpoint when a rule asks for the official rate.

FAQ

Where do the NLB Banka Banja Luka rates come from?

From the bank's own public rates page (https://www.nlb-rs.ba/stanovnistvo/alati-i-dokumentacija/kursna-lista-i-konvertor-valuta), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price NLB Banja Luka shows, with the mid, the spread and the Central Bank of Bosnia and Herzegovina rate added.

Are these the official BAM exchange rates?

No. They are NLB Banja Luka's retail prices for customers. The official rate in Bosnia and Herzegovina is the Central Bank of Bosnia and Herzegovina 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 NLB Banja Luka board updated?

AllRatesToday reads the page every hour. The bank prints no timestamp, so captured_at tells you when the rates were read.

Can I get NLB Banja Luka rates for a past date?

Yes, from 14 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.
