Dominican Republic Central Bank Exchange Rate API: Official DOP Rates as JSON

The Banco Central de la República Dominicana publishes the official exchange rates that accounting, tax, and customs rules in the Dominican Republic 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 bcrd-exchange-rate npm package.

What the BCRD publishes

• Official USD buy and sell rates for the spot market, published each business day since 1991.
• Convertible rates for ~14 more currencies — EUR, GBP, JPY, CAD, CHF, CNY, the Nordics, and the SDR — daily since 2004.
• The bank's own publication date on every response, so a rate is always citable.
• No gaps to trip over — weekends and Dominican holidays resolve to the most recent published rate and are flagged explicitly.

The USD spot series is still the anchor — the dollar dominates Dominican trade, remittances, and pricing — but the convertible table makes the BCRD a full multi-currency official source.

Why official rates, not market rates

A live mid-market feed answers "what is USD/DOP 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 Banco Central de la República Dominicana's published rates, and it never changes after publication.

Get the latest rates (REST)

curl "https://allratestoday.com/api/v1/central-bank/bcrd/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 bcrd-exchange-rate

import { getRate, getLatestRates } from 'bcrd-exchange-rate';

// One pair at the official BCRD rate
const pair = await getRate('USD', 'DOP', { 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 'bcrd-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: 'DOP', 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 BCRD does not print a pair directly, the API resolves it from the bank's published rates — an inverse, or a cross rate via DOP — 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.

Thirty-five years of peso history

The series starts in January 1991 at about 11 pesos per dollar and runs unbroken through the 2003 banking crisis (when the peso halved), dollarization pressure, and the long crawl past 58. For audits, invoice-date lookups, and research it is the official record.

FAQ

Does the Banco Central de la República Dominicana have an official exchange rate API?

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

How often do Banco Central de la República Dominicana rates update?

Once per business day. These are published reference rates, not moving market prices — every API response carries the publication date so you can cite it.

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

Yes. The /central-bank/bcrd/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.
