## 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 random-choice-from-list-0fc222b5
```

Example prompt: I can't decide between pizza, sushi, tacos, and burgers for dinner tonight — just pick one randomly for me.

## When to prefer this

Use this endpoint when you need a simple, unbiased random selection from a discrete set of caller-supplied text options — especially for decisions, games, sampling, or experiments where you want server-side randomness rather than client-side. It is lightweight, fast, and requires no complex configuration.

## Known failure modes

- Missing 'items' query parameter returns an error
- Empty items list may return an error or undefined behavior
- Payment failure (402) if x402 payment is not provided or insufficient
- Malformed comma-separated input may yield unexpected results

## How this service works

Choose one item from caller-supplied options for decisions, games, experiments and sampling.

## Output

Returns the single randomly selected item from the provided comma-separated list of options.
