About Bangladesh Bank

Bangladesh Bank, the central bank of Bangladesh, publishes the Exchange Rate of Taka each business day: the highest and lowest interbank USD/BDT rates at the Dhaka close together with the weighted average rate of the day’s interbank deals, plus taka cross rates for ten more currencies. The rate is determined by interbank supply and demand rather than an administered fixing, and it is the reference Bangladeshi banks, importers and auditors convert at.

One request for the pair you need — USD to BDT at the official Bangladesh Bank rate:

curl "https://allratestoday.com/api/v1/central-bank/bb/latest?source=USD&target=BDT" \
  -H "Authorization: Bearer art_live_your_key"

What comes back — a real response built from the table in force (2026-10-26):

{
  "bank": "bb",
  "name": "Bangladesh Bank",
  "rate_date": "2026-10-26",
  "source": "USD",
  "target": "BDT",
  "rate": 123.75,
  "rate_type": "reference",
  "derived": false,
  "method": "published",
  "age_days": 1,
  "stale": false,
  "cadence": "daily",
  "disclaimer": "Official rates as published by the named central bank. On weekends/holidays the most recent published rate_date is returned."
}

Or the bank's full published table:

curl "https://allratestoday.com/api/v1/central-bank/bb/latest" \
  -H "Authorization: Bearer art_live_your_key"

Node.js / TypeScript client

A dedicated zero-dependency npm package wraps these endpoints — bangladesh-bank-exchange-rate:

npm install bangladesh-bank-exchange-rate
import { getRate } from 'bangladesh-bank-exchange-rate';

const pair = await getRate('USD', 'BDT', { apiKey: 'art_live_...' });
console.log(pair.rate, pair.rate_date);

Zero dependencies, TypeScript types included, and it runs anywhere fetch exists — Node 18+, Bun, Deno, and edge runtimes.

Why use the official Bangladesh Bank rate?

Live market rates move continuously, but tax filings, customs declarations, audits, and statutory accounting in Bangladesh and beyond typically require the official rate published by Bangladesh Bank for a given date — a fixed, citable number that never changes after publication. This API serves those published tables with the bank's own rate_date on every response; weekends and holidays return the most recent published date, which is the rate compliance rules require you to apply.

Pairs the bank doesn't print directly are resolved from its table (inverse or cross via BDT) and explicitly flagged "derived": true — so what the bank printed and what was computed are never confused.

Endpoints

Full parameter reference in the API documentation. Every request counts toward your plan's monthly quota — rates change once per business day, so caching a published table locally makes a small quota go far.
