NBKR Exchange Rate API: Official Kyrgyz Som Rates as JSON

The National Bank of the Kyrgyz Republic publishes the official exchange rates that accounting, tax, and customs rules in Kyrgyzstan 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 nbkr-exchange-rate npm package.

What the NBKR publishes

• Daily official rates for the majors (USD, EUR, RUB, KZT, CNY) — the som rates Kyrgyz accounting and customs practice cite.
• A 40+ currency weekly table on top, covering the long tail.
• The bank's own rate date on every response — the NBKR dates rates for the following day, CBR-style, and the API preserves that.
• No gaps to trip over — weekends resolve to the most recent published rates and are flagged explicitly.

Kyrgyzstan sits on the Russia–Central Asia remittance corridor, and the NBKR official som table — dollar, ruble and tenge above all — is the number its banks, transfer operators and tax practice reference.

Why official rates, not market rates

A live mid-market feed answers "what is USD/KGS 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 National Bank of the Kyrgyz Republic's published rates, and it never changes after publication.

Get the latest rates (REST)

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

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

// One pair at the official NBKR rate
const pair = await getRate('USD', 'KGS', { 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 'nbkr-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: 'KGS', 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 NBKR does not print a pair directly, the API resolves it from the bank's published rates — an inverse, or a cross rate via KGS — 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 XML feeds serve the current tables only, so our series accumulates from August 2026 forward — dailies for the majors, weeklies for the long tail, each stored with the NBKR's own rate date.

FAQ

Does the National Bank of the Kyrgyz Republic have an official exchange rate API?

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

How often do National Bank of the Kyrgyz Republic rates update?

Daily for the majors and weekly for the long tail. The NBKR dates each table for the following day, like the Bank of Russia — the API preserves the bank's own dating so citations stay exact.

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

Yes. The /central-bank/nbkr/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.
