Why use bank board rates through an API?
The Bank of Thailand 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.

Frequently asked questions
Is the Bangkok Bank rate the official Thailand exchange rate?
No. Bangkok Bank sets its own buying and selling rates and changes them through the day. The official rate is published once per business day by the Bank of Thailand; it is shown in the Official column and is the figure accounting, tax and customs rules refer to.
Which Bangkok 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 THB, the buy rate applies. Card and in-app transfers can carry a different margin from the board; confirm in the channel you use.
How current is this table?
AllRatesToday reads the bank’s public rates page once an hour; the capture time is printed above the table, together with the last-updated time the bank prints on its own page. Rates may have changed since.
