Alpha Bank Exchange Rate API: EUR Buy and Sell Rates as JSON

Alpha Bank, founded in 1879 and based in Athens, is one of Greece’s four systemic banks. Its exchange rate bulletin lists buying and selling prices for about 25 currencies for amounts up to USD 15,000, with separate columns for currency and bank notes. 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 Greece, and the calls that return them.

What the Alpha Bank board shows

• 25 currencies against the euro: ALL, AUD, CAD, CHF, CNY, CZK, DKK, GBP, HKD, HUF, ILS, JPY, MKD, NOK, NZD, PEN, PLN, RON, RSD, RUB, SEK, SGD, TRY, USD and ZAR. Every value is EUR per 1 unit of the foreign currency.
• The foreign currency (non-cash) buy / sell pair. Greek banks publish a daily exchange rate bulletin (δελτίο τιμών συναλλάγματος) quoting foreign currency per 1 euro, usually with separate columns for currency (non-cash) and bank notes; the non-cash pair is shown here, inverted to euros per unit. The European Central Bank official rate is shown next to each row.
• USD on 15 November 2026: Alpha Bank bought at 0.8784 and sold at 0.9328 EUR, a spread of 6.01%. The European Central Bank official rate was 0.9048, so the bank's mid sat +0.09% from it.
• The bank's own timestamp. The page prints a last-updated stamp (15/11/2026 01:54 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 JPY (5.99%), NZD (6.00%), PLN (6.00%) and the widest USD (6.01%), GBP (6.01%), AUD (6.00%). 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 European Central Bank rate is the one tax, accounting and customs rules in Greece name; nobody transacts at it. Alpha Bank'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 Alpha Bank rates come from?

From the bank's own public rates page (https://www.alpha.gr/el/idiotes/support-center/nomokanonistiko-plaisio/deltio-timon-sunallagmatos), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Alpha Bank shows, with the mid, the spread and the European Central Bank rate added.

Are these the official EUR exchange rates?

No. They are Alpha Bank's retail prices for customers. The official rate in Greece 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 Alpha Bank 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 Alpha Bank 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.
