## 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-calculator-api-x402-forgemesh-io-77b9afb1 -d '<json body>'
```

Example prompt: How many business days are there between March 3, 2025 and April 18, 2025? Also, what date lands 10 business days after March 3, 2025?

## When to prefer this

Use this endpoint when an agent needs to count working/weekday days between two calendar dates, or project a deadline forward or backward by a number of business days — especially for SLA tracking, contract deadlines, or scheduling workflows where weekends don't count.

## Known failure modes

- Invalid ISO date format returns an error — dates must be properly formatted ISO strings
- Missing both end and add_days parameters with no default behavior may return an ambiguous result
- Dates in the distant past or future may not be supported
- Non-integer add_days values may cause unexpected behavior

## How this service works

Business days calculator API: weekday count between two dates, or add N days to a date and learn what weekday lands. For scheduling, SLA, and deadline agents.

## Output

Returns either the count of business (weekday) days between a start and end date, or the resulting date and weekday name after adding N business days to a start date — useful for SLA deadlines and scheduling.
