## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nbu-data-ukraine-official-uah-exchange-rates-92831d40
```

Example prompt: What is the official NBU hryvnia exchange rate for USD and EUR today? I need the legally official rates for a Ukrainian invoice.

## When to prefer this

Choose this endpoint when you need the legally official UAH exchange rate as published by the National Bank of Ukraine — required for Ukrainian accounting, tax filings, customs declarations, and official invoicing. It provides historical rates back to 1996, covers 40+ currencies plus gold, silver, and SDR, and returns English names alongside Ukrainian names. Prefer this over generic FX APIs when Ukrainian legal compliance is required.

## Known failure modes

- Date out of range (before 1996-09-02 or beyond tomorrow Kyiv time) returns an error
- Invalid or unsupported currency ISO code returns an empty rates array or error
- Malformed date format (not YYYY-MM-DD) returns a validation error
- Network or upstream NBU API unavailability may return a 5xx error
- Currency code not published by NBU returns no rate entry

## How this service works

Official National Bank of Ukraine (NBU) exchange rates of the hryvnia (UAH) on a date: 40+ currencies, gold, silver and SDR, with English names. Call it when you need the legally official UAH rate for Ukrainian accounting, tax, invoices or customs, or to convert to/from UAH on a given date. Params: date (YYYY-MM-DD, default today in Kyiv), currency (ISO code, optional; omit for all).

## Output

Returns a JSON object with the date, base currency (UAH), and an array of currency rate objects each containing: ISO code, English name, Ukrainian name, numeric code, units, UAH rate per units, UAH rate per single unit, the date the rate was set, and a special-conditions flag for USD. Also includes metadata such as source URL, retrieval timestamp, caching status, and terms.
