Citadele Exchange Rate API: EUR Buy and Sell Rates as JSON

Citadele banka is a Latvian bank with branches in Estonia and Lithuania. Its rates page lists non-cash buy and sell rates against the euro for 12 currencies, next to the ECB rate. This guide shows how to read that board as JSON: what the rates mean, how they compare with the European Central Bank official rate and with other banks in Latvia, and the calls that return them.

What the Citadele board shows

• 12 currencies against the euro: AUD, CAD, CHF, CNY, CZK, DKK, GBP, JPY, NOK, PLN, SEK and USD. Every value is EUR per 1 unit of the foreign currency.
• The non-cash (bezskaidras naudas) exchange rate, buy / sell pair. Latvian banks quote units of foreign currency per 1 euro for non-cash exchange, often in columns written from the customer’s side; they are shown here inverted to euros per unit. The European Central Bank reference rate is shown next to each row.
• USD on 15 November 2026: Citadele bought at 0.8865 and sold at 0.9268 EUR, a spread of 4.44%. The European Central Bank official rate was 0.9048, so the bank's mid sat +0.20% from it.
• No timestamp on the bank's page. Citadele 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 15 November 2026, the day collection started. 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 GBP (4.31%), DKK (4.40%), SEK (4.42%) and the widest CHF (5.08%), PLN (5.04%), AUD (5.01%). 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.

USD at Citadele and other banks in Latvia

USD on the 5 boards AllRatesToday reads in Latvia, all captured on 15 November 2026 (the European Central Bank official rate was 0.9048):

Board rate or official rate?

The European Central Bank rate is the one tax, accounting and customs rules in Latvia name; nobody transacts at it. Citadele'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 European Central Bank endpoint when a rule asks for the official rate.

FAQ

Where do the Citadele rates come from?

From the bank's own public rates page (https://www.citadele.lv/lv/rates/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Citadele shows, with the mid, the spread and the European Central Bank rate added.

Are these the official EUR exchange rates?

No. They are Citadele's retail prices for customers. The official rate in Latvia is the European Central Bank 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 Citadele 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 Citadele rates for a past date?

Yes, from 15 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.
