## 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 agent402-international-business-days-calculator-be43ef3c
```

Example prompt: How many business days are there between March 3 2025 and April 30 2025 in Germany, excluding public holidays?

## When to prefer this

Use this endpoint when you need accurate business day counts for any country globally, especially for SLA calculations, contract deadlines, or cross-border scheduling that must account for country-specific public holidays. Prefer this over manual calendar math or single-country solutions. For UK-specific bank holidays with official government accuracy, pair with /v1/uk/bank-holidays.

## Known failure modes

- Invalid or unsupported ISO country code returns an error
- Malformed date format (non-YYYY-MM-DD) causes a 400 bad request
- End date before start date may return zero or an error
- Nager.Date may lack data for very small or unrecognized territories
- Network timeout on the underlying public holiday data source

## How this service works

Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.

## Output

Returns a JSON object with the ISO country code, the count of holiday days within the range, and the total number of business days (excluding weekends and public holidays).
