UniCredit Bank Czech Republic Exchange Rate API: CZK Buy and Sell Rates as JSON

UniCredit Bank Czech Republic and Slovakia is the UniCredit group's bank in Czechia and one of the country's largest lenders. Its exchange-rate list gives non-cash (devizy) and cash (valuty) buy and sell rates for about 21 currencies, with the Czech National Bank's rate alongside. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Czech National Bank official rate and with other banks in the Czech Republic, and the calls that return them.

What the UniCredit CZ board shows

• 21 currencies against the Czech koruna: AUD, BAM, CAD, CHF, CNY, DKK, EUR, GBP, HKD, HUF, JPY, KRW, NOK, NZD, PLN, RON, RSD, SEK, SGD, TRY and USD. Every value is CZK per 1 unit of the foreign currency.
• The non-cash (devizy) buy / sell pair. Czech banks publish two boards: valuty (cash, over the counter) and devizy (non-cash, used for transfers and card or account conversions). The pair here is the non-cash board. The Czech National Bank sets one official rate each business day, which accounting and tax rules refer to.
• USD on 15 November 2026: UniCredit CZ bought at 21.275 and sold at 22.818 CZK, a spread of 7.00%. The Czech National Bank official rate was 22.101, so the bank's mid sat -0.25% from it.
• The bank's own timestamp. The page prints a last-updated stamp (2026-11-13T05:41:32Z 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 NOK (6.99%), BAM (6.99%), SGD (7.00%) and the widest CNY (11.98%), TRY (7.09%), KRW (7.02%). 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 Czech National Bank rate is the one tax, accounting and customs rules in the Czech Republic name; nobody transacts at it. UniCredit CZ'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 Czech National Bank endpoint when a rule asks for the official rate.

FAQ

Where do the UniCredit Bank Czech Republic rates come from?

From the bank's own public rates page (https://www.unicreditbank.cz/cs/obcane/kurzovni-listek.html), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price UniCredit CZ shows, with the mid, the spread and the Czech National Bank rate added.

Are these the official CZK exchange rates?

No. They are UniCredit CZ's retail prices for customers. The official rate in the Czech Republic is the Czech National 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 UniCredit CZ 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 UniCredit CZ 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.
