## 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 business-days-counter-a217c420
```

Example prompt: How many business days are there between March 3, 2025 and April 18, 2025 in the US, excluding public holidays?

## When to prefer this

Use this endpoint when you need a quick, accurate count of business days between two dates, especially when national public holidays need to be excluded. Ideal for contract timelines, payment term calculations, project planning, and SLA compliance checks where weekends and country-specific holidays must be skipped. Prefer this over manual date math or generic calendar libraries when working with multiple countries' holiday calendars.

## Known failure modes

- Invalid date format (non-YYYY-MM-DD) returns an error
- End date before start date may return zero or an error
- Unsupported or invalid ISO country code may ignore holiday exclusion or return an error
- Missing required start or end parameters returns a 400-level error
- Very large date ranges may produce unexpected results

## How this service works

Count business days between two dates (inclusive), skipping weekends and optional national public holidays (ISO country code).

## Output

Returns a JSON object with the count of business days in the specified date range (inclusive, excluding weekends and optionally national public holidays) and the number of holidays excluded from the count. Example: {"business_days": 21, "holidays_excluded": 1}.
