Banque Centrale du Congo Exchange Rates API — banque-centrale-du-congo-exchange-rate

Official Banque Centrale du Congo (DR Congo) daily exchange rates for Node.js and TypeScript. The published central bank rates behind tax filings, customs valuations, audits, and compliant invoicing — not market estimates, but the numbers Banque Centrale du Congo itself prints, every business day.

🚀 Why this client?

• 🏛️ Official published rates — Banque Centrale du Congo's own table, with the publisher's own rate_date on every response
• 📅 History from 2026 — this source publishes only its current table, so the archive builds forward from the day we started collecting
• 🔀 Published vs derived, always flagged — computed inverse/cross pairs carry derived: true, never mixed with official prints
• ⚡ Zero dependencies — pure ESM + CJS over global fetch; Node 18+, Bun, Deno, and edge runtimes
• 🔷 Type-safe — full TypeScript definitions shipped with the package
• 🧾 Compliance-grade metadata — rate_type, publication date, and source disclaimer on every response

Official rate, not mid-market: every value here is a number Banque Centrale du Congo itself published, fixed once printed and carrying the central bank's own rate_date — what filings and audits require. Need the live mid-market rate for pricing or display instead? Use the mid-market API or @allratestoday/sdk. The two can diverge by several percent.

📈 Latest published table

The image is rendered live from the keyless endpoint, so it follows the central bank's publications on npm and on GitHub alike without a new release. The same table as text is folded below for search and copy-paste: on GitHub a daily Action refreshes it whenever the central bank publishes a new table; on npm it is as of the package's publish date.

Latest pair rate

Free plan and up. Pairs the central bank does not print directly are resolved from its table and flagged (see Published vs derived rates below).

const pair = await getRate('USD', 'CDF', { apiKey: 'art_live_...' });

Response:

{
  bank: 'bcc',
  name: 'Banque Centrale du Congo',
  rate_date: '2026-10-14',   // Banque Centrale du Congo's own publication date
  source: 'USD',
  target: 'CDF',
  rate: 2265.04,
  rate_type: 'middle',
  derived: false,
  method: 'published',
  disclaimer: 'Official rates as published by the named central bank. On weekends/holidays the most recent published rate_date is returned.'
}

Full published table

Free plan and up. The complete table for the latest publication date.

const table = await getLatestRates({ apiKey: 'art_live_...' });
console.log(table.rate_date, table.rates.length);

Response:

{
  bank: 'bcc',
  name: 'Banque Centrale du Congo',
  rate_date: '2026-10-14',

    // … the rest of the published table (21 currencies vs CDF)
  ],
  disclaimer: '…'
}

Table for a date

Paid plans. The official table for any date since 2026 — weekends and holidays return the most recent published date, flagged via published_on_requested_date, which is exactly the in-force rate a filing needs.

import { getRatesForDate } from 'banque-centrale-du-congo-exchange-rate';

const day = await getRatesForDate('2026-06-30', { apiKey: 'art_live_...' });
// Optionally narrow to one pair:
const one = await getRatesForDate('2026-06-30', { apiKey: 'art_live_...', source: 'USD', target: 'CDF' });

Response:

{
  bank: 'bcc',
  requested_date: '2026-06-30',
  rate_date: '2026-06-30',                // the date actually published
  published_on_requested_date: true,      // false when a weekend/holiday fell back
  rates: [ /* the full table for that date */ ],
  disclaimer: '…'
}

Daily time series

Paid plans. One resolved rate per publication date — ready for charting, revaluation runs, or audit workpapers.

import { getHistory } from 'banque-centrale-du-congo-exchange-rate';

const series = await getHistory(
  { source: 'USD', target: 'CDF', from: '2026-01-01', to: '2026-10-14' },
  { apiKey: 'art_live_...' }
);

Response:

{
  bank: 'bcc',
  source: 'USD',
  target: 'CDF',
  from: '2026-01-01',
  to: '2026-10-14',
  count: 152,
  rates: [
    // one entry per publication date
    { date: '2026-10-14', rate: 2265.04, rate_type: 'middle', derived: false, method: 'published' },
    // …
  ],
  disclaimer: '…'
}

Pass { symbol: 'USD' } instead of source/target to get the raw published rows for one currency (all rate types, no pair resolution).

🗺️ Currencies covered

Banque Centrale du Congo currently publishes rates covering 21 currencies against the CDF (as of the latest table):

🇦🇪 AED · 🇦🇴 AOA · 🇦🇺 AUD · 🇧🇮 BIF · 🇨🇦 CAD · 🇨🇭 CHF · 🇨🇳 CNY · 🇪🇺 EUR · 🇬🇧 GBP · 🇮🇳 INR · 🇯🇵 JPY · 🇰🇼 KWD · 🇷🇼 RWF · 🇸🇦 SAR · 🇹🇿 TZS · 🇺🇬 UGX · 🇺🇸 USD · XAF · XDR · 🇿🇦 ZAR · 🇿🇲 ZMW

🏛️ Source

The Banque Centrale du Congo publishes the official exchange-market table for the Congolese franc every business day: mid, buying and selling rates for 21 currencies including the US dollar, euro, SDR and the regional CFA and East African units. It is the reference for customs valuation, tax and public accounting in DR Congo.

• Publisher's own page: Marché officiel des changes · www.bcc.cd
• Publication: every business day; the exact schedule, freshness status and any current delay are on the Banque Centrale du Congo rates page
• In the API: usually by 08:20 UTC (measured over the last 11 publications). Schedule a sync at or after that time and retry hourly until rate_date moves; every response carries the same figure as available_by_utc — see when to poll
• Values are stored unmodified, with the publisher's own rate_date on every row — see the methodology

🧭 Reading the numbers

• value is always quote currency per 1 unit of base currency (base: "EUR", quote: "USD", value: 1.15 means 1 EUR = 1.15 USD).
• Banque Centrale du Congo quotes CDF per 1 unit of foreign currency (e.g. base: "USD", quote: "CDF" means CDF per one US dollar).
• Need the other way round? Ask getRate(target, source) and the API inverts or crosses for you, flagged derived: true — never divide a published rate yourself in a compliance workflow.
• rate_type tells you which of the central bank's series a row belongs to (middle here); some publishers print buy/sell or several fixings for the same pair.

🧩 ERP & accounting systems

Loading the official Banque Centrale du Congo rate into an accounting system is a supported workflow, not a hack. Step-by-step guides with the direction each system expects:

• Dynamics 365 Business Central — built-in Currency Exchange Rate Service, no code
• Xero · QuickBooks Online · SAP S/4HANA and ECC · Odoo

The same keyed endpoints return ?format=csv, ?format=xml and ?format=xlsx, and accept the key as ?api_key= on the URL for importers that cannot send headers:

curl "https://allratestoday.com/api/v1/central-bank/bcc/latest?format=xml&api_key=art_live_..."

🤖 AI agents

• MCP server: npx -y @allratestoday/central-bank-mcp (stdio) or the hosted endpoint https://allratestoday.com/api/mcp — tools for official rates, history, cross-bank comparison and publication calendars
• Already using the general SDK or MCP server? Since 2026-10-01 @allratestoday/sdk 1.4+ has officialRates('bcc') and @allratestoday/mcp-server 0.6+ has a get_official_rates tool — both return this source's latest table with no key, so you can add it without a second dependency
• Claude Code plugin (no key): /plugin marketplace add AllRates-Today/claude-code-plugin then /plugin install allratestoday@allratestoday — bundles both MCP servers plus an /official-rate bcc ... command
• Evaluating? Agents can self-issue a trial key with no signup: POST https://allratestoday.com/api/agent/keys (send Content-Type: application/json) returns a 100-call key valid 7 days that covers the free-plan methods (latest table, pairs); dated tables and history need a paid plan. The MCP servers expose it as request_trial_key

⚖️ Published vs derived rates

If Banque Centrale du Congo does not print a pair directly, the API resolves it from the central bank's own table and says so — official and computed values are never confused:

method	derived	Meaning
published	false	The central bank printed this pair directly
inverse	true	Computed as 1 ÷ the published opposite direction
cross	true	Computed via CDF from two published rates

🛡️ Error handling

Errors are thrown as Error with status (HTTP code) and body (the API's JSON error) attached:

try {
  const pair = await getRate('USD', 'XXX', { apiKey: 'art_live_...' });
} catch (err) {
  console.log(err.message); // human-readable reason
  console.log(err.status);  // e.g. 404
}

Status	Meaning
—	Missing apiKey (thrown before any request)
400	Malformed date or parameters
401	Invalid API key
403	Endpoint needs a paid plan (historical dates & series)
404	Pair or date range not covered by Banque Centrale du Congo
429	Monthly quota exceeded

🔷 TypeScript

Full definitions ship with the package — no @types install:

import type { LatestRates, PairRate, DatedRates, RateEntry, HistoryQuery, RequestOptions } from 'banque-centrale-du-congo-exchange-rate';

📦 CommonJS

const { getRate } = require('banque-centrale-du-congo-exchange-rate');

getRate('USD', 'CDF', { apiKey: 'art_live_...' }).then((pair) => console.log(pair.rate));

💡 Quota tips

• Rates change once per business day — cache the published table locally and a small monthly quota goes a long way.
• Every request counts toward your AllRatesToday quota, shared across all AllRatesToday endpoints on your key.
