## 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 market-and-holiday-calendar-is-holiday-checker-6fd70c4d
```

Example prompt: Is July 4th 2025 a public holiday in the US, and if so, is it a business day? Also tell me what the next holiday after that date is.

## When to prefer this

Choose this endpoint when you need to check a specific date for a specific country to determine holiday and business day status in a single call, especially when you also need to know the next upcoming holiday. Prefer this over the 'public holidays for a year' endpoint when checking a single date rather than browsing a full calendar. Ideal for scheduling, logistics, payroll, and compliance workflows where a single date decision must be validated quickly.

## Known failure modes

- Missing required query parameters (country or date) returns an error
- Invalid date format (not YYYY-MM-DD) causes a parse error
- Unsupported country code returns no holiday data or an error
- Degraded mode flag set true if holiday data source is partially unavailable
- Regional holidays may not be flagged for all sub-regions of a country

## How this service works

Is a date a public holiday in a country? Also whether it is a business day and the next holiday after it.

## Output

Returns a structured response indicating whether the queried date is a public holiday, a regional holiday, a weekend, and/or a business day in the given country. Includes the holiday name(s), local name(s), affected regions, a plain-language summary and verdict, and the next upcoming holiday after the queried date. May also include a data source URL and degraded-mode flag.
