## 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 agent402-tools-uuid-generator-a27b243a
```

Example prompt: Generate 5 random UUIDs for me — use version 4.

## When to prefer this

Use this endpoint when you need cryptographically random or time-ordered unique identifiers (UUIDs) without setting up a local library, especially in agentic workflows that require unique IDs for database records, resource creation, or distributed systems. Prefer version 7 when sortability/chronological ordering matters, and version 4 for pure randomness.

## Known failure modes

- Invalid version parameter (not 4 or 7) — returns error response
- Count out of range (less than 1 or greater than 100) — returns error response
- Payment failure or insufficient USDC balance — returns 402 Payment Required

## How this service works

Generate UUIDs. ?version=4 (default, random) or 7 (time-ordered), ?count=1..100.

## Output

Returns a JSON object containing one or more UUIDs (version 4 random or version 7 time-ordered), with count matching the requested amount (1–100).
