## 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 citiview-public-holidays-business-day-calculator-d77babdf
```

Example prompt: How many business days are there between March 3 and April 18, 2025 in the US? Also, what public holidays fall in that range?

## When to prefer this

Choose this endpoint when you need accurate public holiday data across 100+ countries with optional sub-national (state/province) granularity, or when you need to perform business-day arithmetic (count days between dates, add business days, check if a date is a working day) that respects country-specific and regional holiday calendars. It is especially useful for scheduling, payroll, invoice due dates, and SLA calculations that must account for local holidays.

## Known failure modes

- Missing required 'country' query parameter returns a 400 error
- Invalid or unsupported ISO country code returns an error or empty holiday list
- Malformed date format (not YYYY-MM-DD) causes a parsing error
- Missing 'from' date when using 'add_business_days' or date-range parameters returns an error
- Unsupported region/province code may return no regional holidays or an error

## How this service works

Public holidays for 100+ countries (optional state/province), plus business-day math: count business days between two dates, add N business days to a date, or check if a date is a business day.

## Output

Returns a JSON object containing a list of public holidays for the specified country (and optional region/year), along with computed business-day results such as the count of business days between two dates, the resulting date after adding N business days, or a boolean indicating whether a given date is a business day.
