## 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 oromi-uk-working-days-calculator-47ffaf31
```

Example prompt: What date will it be 10 UK working days from 2026-07-21? I need to account for UK bank holidays.

## When to prefer this

Choose this endpoint when you need UK-specific working day calculations that correctly exclude UK bank holidays (not just weekends), such as for legal notice periods, payment terms, settlement dates, or compliance deadlines governed by UK business calendar rules. Prefer over generic date libraries that may not include up-to-date UK bank holiday data.

## Known failure modes

- Missing required 'from' parameter returns an error
- Supplying both 'to' and 'add' simultaneously is invalid as they are mutually exclusive
- Invalid date format (non-YYYY-MM-DD) causes a parsing error
- Payment failure via x402 protocol if USDC balance is insufficient

## How this service works

Machine-payable APIs for AI agents, paid per call in USDC via the x402 protocol: UK business data (Companies House), UK property market data (HM Land Registry), website agent-readiness audits, and crypto market context.

## Output

A JSON object containing the input start date (from), the calculated result date (result_date in YYYY-MM-DD format), and the number of working days added (working_days_added) — all accounting for UK weekends and bank holidays.
