Halyk Bank is Kazakhstan’s largest bank, with roots in the national savings bank. It publishes separate boards for individuals and companies; the individuals’ board covers the main currencies — US dollar, euro, rouble, pound, Swiss franc and yuan — against the tenge. This guide shows how to read that board as JSON: what the rates mean, how they compare with the National Bank of Kazakhstan official rate, and the calls that return them.

## What the Halyk board shows

- **6 currencies against the Kazakhstani tenge**: CHF, CNY, EUR, GBP, RUB and USD. Every value is KZT per 1 unit of the foreign currency.
- **The individuals board buy / sell pair.** The tenge floats, and Kazakh banks post separate boards for individuals and for companies, changing them through the day. The pair here is the board for individuals. The National Bank of Kazakhstan sets one official rate per day, which tax and customs use.
- **USD on 13 November 2026**: Halyk bought at 441.85 and sold at 448.85 KZT, a spread of 1.57%. The National Bank of Kazakhstan official rate was 443.62, so the bank's mid sat +0.39% from it.
- **The bank's own timestamp.** The page prints a last-updated stamp (`2026-11-13` on the board above), returned as `bank_updated_at` next to our `captured_at`.
- **Every day's board is kept permanently, from 13 November 2026, the day collection started.** Read one past day with `?date=`, or a range for one currency with the `/history` endpoint (paid plans).

## Spreads across the board

On the 13 November 2026 board the tightest spreads were USD (1.57%), EUR (1.63%), GBP (3.39%) and the widest CNY (14.97%), RUB (6.84%), CHF (3.61%). Spread is (sell − buy) ÷ mid: what a round trip through the bank costs, before any fees. The API returns it on every row as `spread_pct`, so you can rank currencies or alert when a bank widens its board.

## Get the board (REST)

You need an API key; the [free key](https://allratestoday.com/register/) works. The full board:

```
curl "https://allratestoday.com/api/v1/bank-rates/kz/halyk" \
  -H "Authorization: Bearer art_live_your_key"
```

What comes back (the 13 November 2026 board, first three rows):

npm install @allratestoday/sdk

const client = new AllRatesToday({ apiKey: 'art_live_your_key' });

// Halyk Bank's USD row
const r = await client.bankRates('kz', { bank: 'halyk', ccy: 'USD' });
console.log(`Halyk buys USD at ${r.buy}, sells at ${r.sell} KZT`);

// The board as it stood on a past day
const past = await client.bankRates('kz', { bank: 'halyk', date: '2026-11-13' });
console.log(past.snapshot_date, past.rates.length);
```

## Python

```

## Board rate or official rate?

The National Bank of Kazakhstan rate is the one tax, accounting and customs rules in Kazakhstan name; nobody transacts at it. Halyk's board is the price a customer actually gets. The API puts both on every row: `official` is the central bank's rate for the same currency and `vs_official_pct` is how far the bank's mid sits from it. Use the board to show customers a real price, compare banks for a remittance, or keep a dated record of what the bank quoted; use the [National Bank of Kazakhstan endpoint](https://allratestoday.com/central-bank-rates-api/nbk/) when a rule asks for the official rate.

## FAQ

### Where do the Halyk Bank rates come from?

From the bank's own public rates page (https://halykbank.kz/en/exchange-rates), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Halyk shows, with the mid, the spread and the National Bank of Kazakhstan rate added.

### Are these the official KZT exchange rates?

No. They are Halyk's retail prices for customers. The official rate in Kazakhstan is the National Bank of Kazakhstan rate, which the API returns as `official` on each row where the central bank has one, and in full from the central-bank endpoint.

### How often is the Halyk board updated?

AllRatesToday reads the page every hour. The bank's own last-updated stamp is returned as `bank_updated_at`, so you can tell a fresh read of an unchanged board from a new board.

### Can I get Halyk rates for a past date?

Yes, from 13 November 2026 onward; every day's board is kept permanently. Add `?date=YYYY-MM-DD` for one day: the response is the board captured that day, or the nearest earlier day within five days, with `date_requested` and `snapshot_date` added. For a range, `/history?ccy=USD&from=…&to=…` returns one row per day as JSON, CSV, XML or XLSX on paid plans.

### Do I need an API key?

Yes. Commercial bank boards need an API key; any plan works, the free key included, and each call counts against the plan. Public pages or widgets that show the rates need a visible link to allratestoday.com.
