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 manylives-me-uuid-hex-generator-4cdd156b
```

Example prompt: Can you generate 5 fresh random UUIDs for me? I also want a random hex string alongside them.

## When to prefer this

Choose this endpoint when you need cryptographically random UUID v4 values or raw hex bytes on demand, especially in bulk (up to 50 at once), without setting up a local library or depending on a platform-specific UUID function. It is ideal for agents that need to mint unique identifiers for records, sessions, jobs, or tokens at runtime via a simple HTTP call.

## Known failure modes

- count parameter exceeds 50 — server likely returns an error or caps at 50
- count parameter is 0 or negative — undefined behavior, may return an error
- non-numeric count value — query param validation may reject the request
- payment not included or invalid — HTTP 402 returned, no UUIDs generated
- service unavailability — HTTP 5xx, no output

## How this service works

Fresh random identifiers from a secure generator: UUID v4 (up to 50) plus random hex bytes.

## Output

Returns a JSON object containing an array of UUID v4 strings (up to 50, quantity controlled by the 'count' query param) and a random hex byte string, both freshly generated from a secure random source on each call.
