Bank of Jamaica Exchange Rate API: Official JMD Rates as JSON

The Bank of Jamaica publishes the official exchange rates that accounting, tax, and customs practice in Jamaica reference — published official rates, not moving market prices. This guide shows how to pull them as JSON: via a REST endpoint or the zero-dependency bank-of-jamaica-exchange-rate npm package.

A hundred-currency table from an island economy

The BOJ publishes daily indicative buying and selling rates built from authorized dealers’ trading — and the table is unusually broad: over 120 living currencies, from the US dollar that dominates Jamaica’s remittance inflows to the East Caribbean dollar and the region’s pesos and gourdes. It is the island’s official reference for a heavily dollarised trade economy.

Why official rates, not market rates

A live mid-market feed answers "what is USD/JMD trading at right now?" — the right tool for checkouts and dashboards. But accountants, auditors, and tax authorities ask a different question: "which rate were you required to use for this date?" That answer comes from the Bank of Jamaica’s published rates, and it never changes after publication.

Get the latest rates (REST)

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

The response is the bank's most recent published table — every rate and the publication date. The latest rates are available on every plan, including the free tier (300 requests/month, no credit card).

The npm SDK

npm install bank-of-jamaica-exchange-rate

import { getRate, getLatestRates } from 'bank-of-jamaica-exchange-rate';

// One pair at the official rate
const pair = await getRate('USD', 'JMD', { apiKey: 'art_live_...' });
console.log(pair.rate, pair.rate_date);

// The bank's full published table
const table = await getLatestRates({ apiKey: 'art_live_...' });
console.log(table.rate_date, table.rates.length);

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

Historical rates for an invoice date

import { getRatesForDate, getHistory } from 'bank-of-jamaica-exchange-rate';

const day = await getRatesForDate('2026-08-18', { apiKey: 'art_live_...' });

const series = await getHistory(
  { source: 'USD', target: 'JMD', from: '2026-01-01' },
  { apiKey: 'art_live_...' }
);

Historical dates and time series need a paid plan; the latest rates stay free.

Published vs derived pairs

If the Bank of Jamaica does not print a pair directly, the API resolves it from the bank's published rates — an inverse, or a cross via JMD — and flags it derived: true with the method used. Official and computed values are never silently mixed, which is exactly the distinction an auditor will ask about.

The archive

The daily archive reaches back to mid-2000, covering the Jamaican dollar’s long slide from ~42 to ~158 per US dollar.

FAQ

Does the Bank of Jamaica have an official exchange rate API?

The bank publishes its official rates on its own site, and AllRatesToday serves the same published rates as clean JSON via REST or the bank-of-jamaica-exchange-rate npm package. The latest table is free.

How do I get the official Jamaica exchange rate for a past date?

The rates-for-date endpoint returns the official table for any archived date; non-publication days resolve to the most recent published date and are flagged, so audit trails stay honest. Historical dates require a paid plan; latest rates are free.

The BOJ table lists dead currencies — are they served?

No. The bank still prints indicative values for long-dead currencies (Deutsche Mark, French franc, Cyprus pound and more, derived from euro conversion); the API deliberately serves only living ISO currencies.
