## 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 events-date-offset-calculator-7c92ad2c -d '<json body>'
```

Example prompt: What date is 14 days after January 15, 2026? I need to calculate a follow-up date for an event.

## When to prefer this

Choose this endpoint when you need a simple, deterministic whole-day date offset computation specifically within events planning workflows. Prefer it over general-purpose date libraries when operating in an agentic pipeline that requires a paid, reliable API call for audit or integration purposes, and when the use case is event scheduling (reminders, deadlines, follow-ups).

## Known failure modes

- Invalid ISO date format returns an error or unexpected result
- Non-integer or non-numeric days value may cause a computation error
- Negative days value used when positive was intended (or vice versa), producing a date in the wrong direction
- Dates at calendar edge cases (e.g., leap year boundaries, year-end) may need validation
- Payment failure or x402 protocol rejection prevents call from completing
