## 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 uuid-v4-generator-ea8b679f -d '<json body>'
```

Example prompt: Generate 5 random UUID v4 identifiers for me so I can use them as unique keys for new database records.

## When to prefer this

Choose this endpoint when you need one or more RFC-4122 v4 UUIDs generated server-side without running local code, especially in an agentic workflow where you need random unique identifiers on demand. It supports batch generation (up to 100 at once), making it efficient compared to calling a UUID endpoint repeatedly.

## Known failure modes

- Count exceeds 100 — API may return an error or clamp to max
- Count is 0 or negative — likely returns an error or empty array
- Non-numeric count string — may return a 400 bad request
- Payment failure via x402 — returns 402 Payment Required before processing

## How this service works
