## 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 agent-clock-business-day-add-bd4e94d2 -d '<json body>'
```

Example prompt: What date is 15 business days from September 15, 2025? Use the business day add tool to calculate it.

## When to prefer this

Use this endpoint when you need to add a precise count of business days to a date, especially for deadline calculations, SLA computations, contract milestones, or any scheduling logic that must skip weekends. It is purpose-built for AI agent workflows with per-call USDC micro-payment pricing and no API key setup required, making it ideal for lightweight, on-demand business calendar arithmetic.

## Known failure modes

- Invalid or missing start date returns an error response
- Negative or non-integer business day counts may return an error
- Malformed request body (missing required fields) returns 400-level error
- Payment failure via x402 protocol returns 402 Payment Required

## How this service works

Time and schedule micro-tools for AI agents: UTC now, cron next-runs, timezone conversion, business-day math, and deadline checks. Pay with USDC via x402 — no API keys.

## Output
