Bank’s own last-updated stamp: 2026-11-13 23:22:40 (Seoul), notice 450 (as printed on its page, local time).

Board shown: Remittance receive / send (telegraphic transfer).

Response fields

Errors and limits

• 401 — no key or an invalid key. Any plan’s key works, the free one included.
• 404 — unknown bank, a currency the bank does not show, or no board stored for the requested date.
• 400 — date not in YYYY-MM-DD form, or in the future.
• Each call counts against your plan. Responses can be cached for five minutes; past-day boards never change.
• Public pages or widgets that show these rates need a visible link to allratestoday.com.

Why use bank board rates through an API?

The Bank of Korea official rate is what accounting, tax and customs rules name, but it is not what a customer pays at the counter or in an app. Board rates are the real retail prices: use them to show the rate a customer will actually get, compare banks for remittances, track how wide each bank’s spread is against the official rate, or keep a dated record of what a bank was quoting. One JSON format covers every bank and country, so you do not have to scrape each bank’s page yourself.

History API: KB Kookmin Bank rates for past dates

One day, every plan including the free key: /api/v1/bank-rates/kr/kbstar?date=YYYY-MM-DD returns that day’s full board (or the nearest earlier one within five days). A range for one currency, one row per day, paid plans: /api/v1/bank-rates/kr/kbstar/history with ccy, from and to (default: the last year). Billed one call per month covered.

Is the KB Kookmin Bank rate the official South Korea exchange rate?

Which KB Kookmin Bank rate applies when I send money abroad?

The sell rate: you are buying foreign currency from the bank. When you convert foreign currency into KRW, the buy rate applies. Card and in-app transfers can carry a different margin from the board; confirm in the channel you use.
