## 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 foundry-business-days-calculator-1620e895 -d '<json body>'
```

Example prompt: How many business days are there between 2026-11-01 and 2026-11-30? I also want to know the weekend days and total calendar days.

## When to prefer this

Use this endpoint when you need a quick, structured breakdown of business days vs weekend days vs calendar days for any date range, without needing public holiday exclusions. Ideal for scheduling, project planning, contract duration calculations, and invoice windows where a simple Monday–Friday count suffices.

## Known failure modes

- Invalid date format (non-YYYY-MM-DD input) may cause an error or unexpected result
- End date before start date may return zero or negative counts
- Missing or malformed input string returns an error
- Network or server unavailability on the Render-hosted service
