## 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 fittings-business-days-calculator-7ddd6e34
```

Example prompt: What date is 10 business days from 2025-06-01, skipping July 4th (2025-07-04)?

## When to prefer this

Choose this endpoint when you need to compute a calendar date offset by a specific number of business days, accounting for weekends and custom holiday lists. It is ideal for SLA tracking, payment settlement windows, regulatory deadlines, and any scheduling logic that must skip non-working days. Prefer this over generic date-math libraries when you want a hosted, stateless, API-callable solution with holiday injection support, without managing calendar logic yourself.

## Known failure modes

- Invalid date format (non-ISO YYYY-MM-DD) returns an error
- Missing required 'date' or 'days' query parameters returns a 400-level error
- Malformed holidays array values cause a parsing error
- Very large day offsets may behave unexpectedly if not bounded by the service
- Network or upstream timeout returns a 5xx error
