## 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 workdaychecker-business-day-holiday-lookup-b8b5b1a9
```

Example prompt: Is July 20, 2026 a business day, and if not, when is the next one? Also let me know if there are any upcoming US holidays in that window.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call (no API key required) business calendar lookup — particularly for checking whether a specific date is a workday, finding the next business day, or counting business days in a window. Prefer it over rolling your own calendar logic when you need US holiday awareness built in and want zero setup overhead.

## Known failure modes

- Invalid or unparseable date input returns an error
- Missing required query parameters may return a 400 error
- Network timeout on rare infrastructure issues
- Date far in the future may have incomplete holiday data
