Bai-Tushum Bank Exchange Rate API: KGS Buy and Sell Rates as JSON

Bai-Tushum Bank is a Kyrgyz commercial bank based in Bishkek. Its home page lists cash, non-cash and mobile-banking buy and sell rates for five currencies. This guide shows how to read that board as JSON: what the rates mean, how they compare with the National Bank of the Kyrgyz Republic official rate and with other banks in Kyrgyzstan, and the calls that return them.

What the Bai-Tushum board shows

• 5 currencies against the Kyrgyz som: CNY, EUR, KZT, RUB and USD. Every value is KGS per 1 unit of the foreign currency.
• The non-cash (безналичные) buy / sell pair. Kyrgyz banks print buying and selling rates against the som for the US dollar, euro, rouble and tenge, often with separate cash and non-cash boards and the NBKR rate beside them. The US dollar spread is usually under 1%, while yuan, lira and dirham are quoted much wider. The National Bank of the Kyrgyz Republic official rate is shown next to each row.
• USD on 15 November 2026: Bai-Tushum bought at 87.3 and sold at 87.5 KGS, a spread of 0.23%. The National Bank of the Kyrgyz Republic official rate was 87.4355, so the bank's mid sat -0.04% 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 tightest spreads were USD (0.23%), EUR (1.03%), CNY (3.04%) and the widest KZT (21.05%), RUB (3.29%), CNY (3.04%). 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 National Bank of the Kyrgyz Republic rate is the one tax, accounting and customs rules in Kyrgyzstan name; nobody transacts at it. Bai-Tushum'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 the Kyrgyz Republic endpoint when a rule asks for the official rate.

FAQ

Where do the Bai-Tushum Bank rates come from?

From the bank's own public rates page (https://www.baitushum.kg/ru/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Bai-Tushum shows, with the mid, the spread and the National Bank of the Kyrgyz Republic rate added.

Are these the official KGS exchange rates?

No. They are Bai-Tushum's retail prices for customers. The official rate in Kyrgyzstan is the National Bank of the Kyrgyz Republic 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 Bai-Tushum 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 Bai-Tushum 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.
