Central Bank of The Gambia Exchange Rate API: Official GMD Rates as JSON

The Central Bank of The Gambia publishes the official exchange rates that accounting, tax, and customs rules in The Gambia 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 central-bank-of-the-gambia-exchange-rate npm package.

What the CBG publishes

• The daily indicative rate for ~32 currencies in dalasi per unit — around 72.17 per US dollar, 86.13 per euro and 97.26 per pound on 4 September 2026.
• A floating currency — the daily figure is the reference Gambian banks, the revenue authority and remittance operators cite.
• The bank's own date on every response — the CBG dates its valuation table each day, and the API preserves it.
• No gaps to trip over — weekends and Gambian holidays resolve to the most recent published rates and are flagged explicitly.

The dalasi floats, so there is no peg to lean on: the CBG indicative table is the one official print of where the currency stands each day, and the number a Gambian customs valuation or tax filing has to reference.

Why official rates, not market rates

A live mid-market feed answers "what is USD/GMD 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 Central Bank of The Gambia's published rates, and it never changes after publication.

Get the latest rates (REST)

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

The response is the bank's most recent published data — 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 central-bank-of-the-gambia-exchange-rate

import { getRate, getLatestRates } from 'central-bank-of-the-gambia-exchange-rate';

// One pair at the official CBG rate
const pair = await getRate('USD', 'GMD', { 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 'central-bank-of-the-gambia-exchange-rate';

// The official rates for an invoice date — non-publication days return
// the most recent published date, flagged via published_on_requested_date.
const day = await getRatesForDate('2026-06-30', { apiKey: 'art_live_...' });

// Time series for one pair
const series = await getHistory(
  { source: 'USD', target: 'GMD', 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 CBG does not print a pair directly, the API resolves it from the bank's published rates — an inverse, or a cross rate via GMD — 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.

A fresh official series

The bank publishes the latest valuation table only, so our series accumulates from September 2026 forward — every business day's ~32-currency table, stored with the bank's own date, building the queryable archive the source itself never offered.

FAQ

Does the Central Bank of The Gambia have an official exchange rate API?

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

How often do Central Bank of The Gambia rates update?

Once per business day, as an indicative rate for ~32 currencies; the bank dates each day's valuation table and the API preserves that date. These are official indicative rates, not live market prices.

Can I get the CBG rate for a past date, like an invoice date?

Yes. The /central-bank/cbg/rates-for-date endpoint returns the official rates for any archived date. Non-publication days resolve to the most recent published date and are flagged, so your audit trail stays honest. Historical dates require a paid plan; latest rates are free.
