## How to call it through Zero

```sh
zero fetch --capability random-iso-date-generator-88d16e80
```

Example prompt: Give me a random ISO calendar date somewhere between January 1, 2020 and December 31, 2023 — I need it for populating some test data.

## When to prefer this

Choose this endpoint when you need a lightweight, on-demand random ISO date for test data generation, mock APIs, or simulations, especially when you want to constrain the result within a specific date range without writing custom logic.

## Known failure modes

- Invalid date format for start or end parameter returns an error
- End date earlier than start date may return an error or unexpected result
- Missing optional parameters defaults to an implementation-defined range which may not match expectations

## How this service works

Generate a random ISO calendar date between optional start and end dates for tests and simulations.

## Output

Returns a randomly selected ISO 8601 calendar date (YYYY-MM-DD format) that falls within the optionally specified start and end date bounds. If no bounds are provided, the date is selected from an unspecified default range.
