Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 one-engine-uuid-v4-generator-6dfc4282 -d '<json body>'
```

Example prompt: Generate 5 cryptographically random UUID v4 identifiers for me right now — I need them to tag a new batch of records.

## When to prefer this

Choose this endpoint when your agent needs one or more cryptographically secure UUID v4 identifiers on demand without running local code — especially in serverless or sandboxed environments where Math.random() or native UUID libraries are unavailable. It supports batch generation of up to 100 UUIDs per call, making it efficient for provisioning identifiers in bulk at sub-cent cost via x402.

## Known failure modes

- count below 1 or above 100 returns a validation error
- malformed request body returns 400
- payment not attached or insufficient returns 402
- transient Cloudflare Workers error returns 500

## How this service works

Generate one or more cryptographically random UUID v4 identifiers

## Output

Returns an array of one or more UUID v4 strings (e.g. '550e8400-e29b-41d4-a716-446655440000'), generated cryptographically at random. The number of UUIDs matches the requested count (default 1, max 100).
