Central bank rate API

The rate a named institution actually published for a given date, from 102 central banks and 3 tax authorities. Unlike a mid-market rate it never changes after publication, which is what tax filings, customs valuations and audits require. 

curl "https://allratestoday.com/api/v1/central-bank/ecb/latest?source=GBP&target=LKR" \
  -H "Authorization: Bearer YOUR_API_KEY"

{ "bank": "ecb", "rate_date": "2026-08-14", "rate": 0.8643,
  "rate_type": "reference", "derived": false, "method": "published" }
  • Any past date — /central-bank/{bank}/2026-06-30. If the bank did not publish that day you get the most recent prior date, flagged.
  • Every bank at once — /api/v1/central-banks/rates returns all sources for one pair, so you can compare what each institution published.
  • Nothing is guessed — pairs a bank does not print are cross-computed from that bank's own table and returned with "derived": true and the method used. Banks are never mixed.

How GBP/LKR Exchange Rates Work

Exchange rates are determined by supply and demand in the global foreign exchange (forex) market, the largest financial market in the world with over $6 trillion traded daily.

Floating vs Fixed Rates: Most major currencies like GBP and LKR have floating exchange rates, meaning their value is determined by market forces. Some currencies are pegged to another currency (usually USD) at a fixed rate.

Bid and Ask Prices: In forex markets, currencies are quoted with a bid price (what buyers pay) and ask price (what sellers receive). The mid-market rate shown on this page is the midpoint between these two prices.

Rate Fluctuations: The GBP/LKR rate can change every second during trading hours. Major economic announcements, interest rate decisions, and geopolitical events can cause significant moves in either direction.
