## 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-uah-exchange-rate-history-b965a690
```

Example prompt: Can you pull the official NBU hryvnia exchange rate history for EUR from 2024-01-01 to 2024-03-31 and tell me the min, max, and overall percentage change?

## When to prefer this

Choose this endpoint when you need a full daily time-series of NBU official UAH exchange rates over a multi-day period (up to one year) with built-in statistics (min, max, % change) in a single call. It is more efficient than calling a single-date rate endpoint repeatedly and is ideal for charting, averaging, or period-based Ukrainian financial reporting. Prefer this over a spot-rate endpoint when trend analysis or date-range comparisons are required.

## Known failure modes

- Invalid or unsupported currency code returns an error
- Date range exceeding 366 days returns a validation error
- Future dates or unavailable historical dates may return empty data or error
- Malformed date format (not YYYY-MM-DD) triggers a schema validation failure
- Network or payment failure returns HTTP 402 or 5xx

## How this service works

Daily official NBU exchange-rate series of one currency against the hryvnia (UAH) for a period of up to 366 days, plus min, max and % change. Call it to chart or analyse UAH moves, compute averages for Ukrainian reporting, or check a rate across several dates in one paid call. Params: currency (default USD), from and to (YYYY-MM-DD; default the last 31 days).

## Output

A JSON object containing a currency code, date range, base currency (UAH), an array of daily data points (each with date, rate, units, ratePerUnit), and a stats object including min rate with date, max rate with date, first and last rate records, total count, absolute change, and percentage change over the period.
