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.

History API: TMBThanachart Bank (ttb) rates for past dates

One day, every plan including the free key: /api/v1/bank-rates/th/ttb?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/th/ttb/history with ccy, from and to (default: the last year). Billed one call per month covered.
