Central Bank of Suriname Exchange Rate API: Official SRD Rates as JSON

The Central Bank of Suriname publishes the official exchange rates that accounting, tax, and customs practice in Suriname 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-suriname-exchange-rate npm package.

Weighted averages under a float

Since June 2021 the Surinamese dollar floats, and the central bank publishes weighted-average exchange rates — buying and selling for 11 currencies, refreshed up to three times each business day. These are the operative official rates for pricing and settlement in Suriname; the old fixed table from before the float is history, not the current reference.

Why official rates, not market rates

A live mid-market feed answers "what is USD/SRD 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 Suriname’s published rates, and it never changes after publication.

Get the latest rates (REST)

curl "https://allratestoday.com/api/v1/central-bank/cbvs/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 central-bank-of-suriname-exchange-rate

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

// One pair at the official rate
const pair = await getRate('USD', 'SRD', { 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-suriname-exchange-rate';

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

const series = await getHistory(
  { source: 'USD', target: 'SRD', 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 Central Bank of Suriname does not print a pair directly, the API resolves it from the bank's published rates — an inverse, or a cross via SRD — 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 bank’s koerslijst archive is loaded from September 2009 — through the 2016 devaluation, the 2021 float (14 → 21 SRD per dollar in one step) and the slide since. Under the float there are up to three fixings a day; the archive keeps the day’s final fixing, and each new fixing is stored with its publication date as it appears.

FAQ

Does the Central Bank of Suriname 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 central-bank-of-suriname-exchange-rate npm package. The latest table is free.

How do I get the official Suriname 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.

Which of the CBvS tables does the API serve?

The weighted-average (Gewogen Gemiddelde) table — the operative official rates under the float. Historical dates before the June-2021 float return the fixed official rates that applied then, from the bank’s own koerslijst archive; the stale copy of that fixed table still shown on the bank’s current homepage is deliberately not ingested.
