Why use bank board rates through an API?

The Central Bank of Sri Lanka 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: Commercial Bank of Ceylon rates for past dates

A range for one currency, one row per day, paid plans: /api/v1/bank-rates/lk/combank/history with ccy, from and to (default: the last year). Billed one call per month covered.

Frequently asked questions

Is the Commercial Bank of Ceylon rate the official Sri Lanka exchange rate?

No. Commercial Bank of Ceylon sets its own buying and selling rates and changes them through the day. The official rate is published once per business day by the Central Bank of Sri Lanka; it is shown in the Official column and is the figure accounting, tax and customs rules refer to.

Which Commercial Bank of Ceylon rate applies when I send money abroad?

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

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.
