Banque Centrale du Congo Exchange Rate API: Official CDF Rates as JSON

The Banque Centrale du Congo publishes the official exchange rates that accounting, tax, and customs rules in DR Congo 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 banque-centrale-du-congo-exchange-rate npm package.

What the BCC publishes

• The daily "Marché officiel des changes" — mid, buying and selling rates for 21 currencies, in CDF per 1 unit.
• The reference for customs valuation, tax and public accounting in DR Congo.
• Posted in advance — the table for the next business day appears ahead of time, and every response carries the bank's own rate date.
• Rate types kept apart — mid, buy and sell are stored as separate rate types, never averaged together.

The BCC table is the official print for the Congolese franc — around 2,264 per US dollar and 2,633 per euro on the table dated 7 September 2026 — and it is the number customs, the tax administration and public accounts in DR Congo are required to use.

Why official rates, not market rates

A live mid-market feed answers "what is USD/CDF 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 Banque Centrale du Congo's published rates, and it never changes after publication.

Get the latest rates (REST)

curl "https://allratestoday.com/api/v1/central-bank/bcc/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 banque-centrale-du-congo-exchange-rate

import { getRate, getLatestRates } from 'banque-centrale-du-congo-exchange-rate';

// One pair at the official BCC rate
const pair = await getRate('USD', 'CDF', { 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 'banque-centrale-du-congo-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: 'CDF', 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 BCC does not print a pair directly, the API resolves it from the bank's published rates — an inverse, or a cross rate via CDF — 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's archive since 2017 exists only as an in-browser export, so our series accumulates from September 2026 forward — every business day's table, stored with its own date, building the queryable archive Congolese filings can cite.

FAQ

Does the Banque Centrale du Congo have an official exchange rate API?

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

How often do Banque Centrale du Congo rates update?

Once per business day, with the next business day's table posted in advance. Each table carries mid, buying and selling rates for 21 currencies; every API response carries the bank's own rate date.

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

Yes. The /central-bank/bcc/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.
