REST, JavaScript and Python examples." canonical: https://allratestoday.com/blog/crystalbank-exchange-rate-api/ source: AllRatesToday (https://allratestoday.com/) — Markdown mirror of the page above; index of all pages at https://allratestoday.com/llms.txt generated: 2026-11-15T19:12:01.158Z --- CRYSTALBANK is a Ukrainian commercial bank based in Kyiv. Its home page lists buy and sell rates for the US dollar and the euro beside the NBU rate. This guide shows how to read that board as JSON: what the rates mean, how they compare with the National Bank of Ukraine official rate and with other banks in Ukraine, and the calls that return them. ## What the CRYSTALBANK board shows - **2 currencies against the Ukrainian hryvnia**: EUR and USD. Every value is UAH per 1 unit of the foreign currency. - **The buy / sell board, USD and EUR pair.** Ukrainian banks quote the US dollar and euro, and sometimes a few more currencies, in hryvnia per unit, with separate cash and card or online rates that change during the day. The National Bank of Ukraine official rate is shown next to each row. - **USD on 15 November 2026**: CRYSTALBANK bought at 45.28 and sold at 46.1 UAH, a spread of 1.79%. The National Bank of Ukraine official rate was 45.3849, so the bank's mid sat +0.67% from it. - **The bank's own timestamp.** The page prints a last-updated stamp (`15.11.2026` on the board above), returned as `bank_updated_at` next to our `captured_at`. - **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 spreads were USD 1.79%, EUR 2.46%. 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 CRYSTALBANK and other banks in Ukraine USD on the 30 boards AllRatesToday reads in Ukraine, all captured on 15 November 2026 (the National Bank of Ukraine official rate was 45.3849): | Bank | Buy | Sell | Spread | Mid vs official | | --- | --- | --- | --- | --- | | PrivatBank | 45.42 | 45.8716 | 0.99% | +0.57% | | Monobank | 45.43 | 45.8295 | 0.88% | +0.54% | | PUMB | 45.3 | 45.9 | 1.32% | +0.47% | | OTP Bank Ukraine | 45.25 | 45.9 | 1.43% | +0.42% | | UKRSIBBANK | 45.25 | 45.95 | 1.53% | +0.47% | | A-Bank | 45.3 | 46 | 1.53% | +0.58% | | Accordbank | 45.3 | 45.85 | 1.21% | +0.42% | | Globus Bank | 45.35 | 45.95 | 1.31% | +0.58% | | ProCredit Bank Ukraine | 45.2 | 45.75 | 1.21% | +0.20% | | Credit Agricole Bank Ukraine | 45.2 | 46.04 | 1.84% | +0.52% | | Ukreximbank | 45.35 | 45.85 | 1.10% | +0.47% | | Unex Bank | 45 | 46.09 | 2.39% | +0.35% | | RADABANK | 45.2 | 46.1 | 1.97% | +0.58% | | MetaBank | 44.5 | 46.05 | 3.42% | -0.24% | | **CRYSTALBANK** | 45.28 | 46.1 | 1.79% | +0.67% | | Pravex Bank | 45.4 | 45.85 | 0.99% | +0.53% | | Clearing House Bank | 45.3 | 46 | 1.53% | +0.58% | | First Investment Bank (Ukraine) | 45.2 | 45.9 | 1.54% | +0.36% | | BTA Bank (Ukraine) | 45.3 | 45.9 | 1.32% | +0.47% | | Bank Ukrainian Capital | 45 | 46.1 | 2.42% | +0.36% | | Bank Credit Dnipro | 45.4 | 45.85 | 0.99% | +0.53% | | Policombank | 45.4 | 46.2 | 1.75% | +0.92% | | Industrialbank | 45.5 | 46.2 | 1.53% | +1.02% | | Altbank | 45.35 | 46.05 | 1.53% | +0.69% | | MTB Bank | 45.4 | 46.1 | 1.53% | +0.80% | | Bank 3/4 | 45.1 | 45.85 | 1.65% | +0.20% | | Piraeus Bank (Ukraine) | 45.35 | 45.89 | 1.18% | +0.52% | | European Industrial Bank | 45.7 | 46.1 | 0.87% | +1.14% | | Bank Trust-Capital | 45.2 | 45.9 | 1.54% | +0.36% | | Creditwest Bank | 45.3 | 45.75 | 0.99% | +0.31% | CRYSTALBANK had the 25th narrowest USD spread of the 30. One call to `/api/v1/bank-rates/ua` returns every board in the table at once. ## Get the board (REST) You need an API key; the [free key](https://allratestoday.com/register/) works.

The National Bank of Ukraine rate is the one tax, accounting and customs rules in Ukraine name; nobody transacts at it. CRYSTALBANK'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 [National Bank of Ukraine endpoint](https://allratestoday.com/central-bank-rates-api/nbu/) when a rule asks for the official rate. ## FAQ ### Where do the CRYSTALBANK rates come from? From the bank's own public rates page (https://crystalbank.com.ua/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price CRYSTALBANK shows, with the mid, the spread and the National Bank of Ukraine rate added. ### Are these the official UAH exchange rates? No. They are CRYSTALBANK's retail prices for customers. The official rate in Ukraine is the National Bank of Ukraine 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 CRYSTALBANK 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 CRYSTALBANK 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. ## CRYSTALBANK rates, as JSON Free API key, hourly board captures, the official rate alongside.
