## 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`):

zero fetch --capability project-date-offset-calculator-7b8db29c -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need a simple, reliable, project-workflow-oriented date offset calculation by whole days from an ISO date — especially inside automated pipelines where you pay per call and need a deterministic, fast result without spinning up a local date library.

## Known failure modes

- Invalid or malformed ISO date string returns an error
- Non-integer or non-numeric days value may cause unexpected results
- Missing required fields may result in fallback to default values (2026-01-15, 14 days)
- Network or payment authorization failure returns 402 or 5xx error
