## 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 jp-local-pack-api-japan-payroll-combined-summary-7ef5bd26
```

## When to prefer this

Use this endpoint when you need a single combined Japan payroll summary that includes payroll deductions, social insurance grades, tax context, and holiday/business day counts for a specific month — especially in agentic HR automation, payroll verification, or salary simulation workflows requiring Japan-specific compliance data without a separate API key.

## Known failure modes

- Missing or invalid monthly_salary parameter returns an error or zero-placeholder shape preview
- Missing or invalid year_month returns an empty month_context with zero business days
- Unpaid request (no X-PAYMENT header) returns HTTP 402 with shape preview containing all-zero numeric fields
- Out-of-range salary may trigger floor or ceiling applied flags
- Network or Cloudflare worker downtime returns 5xx error
