## 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 uk-business-deadline-calculator-energy-bill-toolkit-a0a33dd6 -d '<json body>'
```

Example prompt: What's the deadline date if I start on 2025-03-01 and need to count 20 business days in Scotland?

## When to prefer this

Use this endpoint when you need jurisdiction-aware UK business day calculations that account for the distinct public holiday calendars of England & Wales, Scotland, and Northern Ireland separately. It is purpose-built for UK regulatory, legal, or energy-sector deadline computations rather than generic international business day calculators.

## Known failure modes

- Invalid division enum value returns a validation error
- startDate in wrong format (not ISO 8601 date) causes a 400 error
- businessDays exceeding 366 or below 0 fails schema validation
- Missing required fields returns a 400 bad request
- Network or server errors return 5xx responses

## How this service works

Pay-per-use EBT screening endpoint
