## 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 project-weekday-counter-d5b06a12 -d '<json body>'
```

Example prompt: How many weekdays are there between January 5, 2026 and January 16, 2026 — I need the count for planning my project sprint?

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.01 USDC) computation of business days between two specific dates for project or workflow scheduling purposes, especially when you want a purpose-built project-oriented weekday counter rather than a generic calendar library call.

## Known failure modes

- Invalid date format causes a parsing error — dates must be ISO 8601 strings (YYYY-MM-DD)
- End date before start date may return zero or an error
- Missing required start or end parameter results in a validation error
- Dates far in the future or past may be unsupported depending on service limits
