Central Bank of Turkmenistan Exchange Rate API: Official TMT (Manat) Rates as JSON

The Central Bank of Turkmenistan publishes the official exchange rates that accounting, tax, and customs rules in Turkmenistan 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-turkmenistan-exchange-rate npm package.

What the CBT publishes

• The official manat rate for about 45 currencies plus the SDR in TMT per unit — 3.5000 per US dollar and 3.9858 per euro on the table dated 26 September 2026.
• A fixed dollar and floating crosses — the dollar has been set at 3.5000 manat since 1 January 2015 (2.85 before that), and every other line is the dollar peg crossed with that currency's market rate, so the euro, pound, yuan and rouble lines move every day.
• The currencies Turkmenistan trades in — the majors, the CIS and Central Asian units (rouble, tenge, som, somoni, sum, manat, lari, dram, hryvnia), the Gulf currencies, the yuan, yen, won and rupee, the Turkish lira and the Iranian rial.
• History back to January 2009 in our API, queryable by exact date or as a series — the manat's first weeks after redenomination, the 2015 devaluation and every table since, one page per publication day at the bank.

Turkmenistan runs a hard dollar peg, so the interesting numbers are the crosses: the bank's euro, rouble and yuan rates are the figures Turkmen banks, customs and state enterprises convert at, and they change daily even though the dollar line has not moved since 2015. The API serves the whole table, dated, for every currency the bank prints.

Why official rates, not market rates

A live mid-market feed answers "what is USD/TMT 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 Turkmenistan's published rates, and it never changes after publication.

Get the latest rates (REST)

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

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

// One pair at the official CBT rate
const pair = await getRate('USD', 'TMT', { 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-turkmenistan-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: 'TMT', 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 CBT does not print a pair directly, the API resolves it from the bank's published rates — an inverse, or a cross rate via TMT — 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 manat since 2009

Our archive starts on 1 January 2009, days after the manat was redenominated, with the dollar at 2.85 and the euro at 4.0185. The dollar was moved to 3.50 on 1 January 2015 and has not changed since; the euro line peaked at 4.3866 in February 2018, bottomed at 3.3429 in September 2022 and stood at 3.9858 on 26 September 2026. For a past invoice date, one call returns the table in force that day; Sundays and holidays resolve to the last published table and are flagged.

FAQ

Does the Central Bank of Turkmenistan have an official exchange rate API?

The CBT 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-turkmenistan-exchange-rate npm package. The latest rates are free (300 requests/month); historical dates need a paid plan.

How often do Central Bank of Turkmenistan rates update?

Once per publication day, Monday to Saturday, as one table of about 45 currencies plus the SDR in manat per unit. Every API response carries the bank's own rate date; Sundays and holidays resolve to the last published table.

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

Yes. The /central-bank/cbt/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 via published_on_requested_date.
