## When to prefer this

Choose this endpoint when you need cryptographically secure UUID v4 identifiers without installing any library or dependency, especially when you need a quick batch of up to 100 UUIDs in a single API call. Ideal for serverless or agent workflows needing unique IDs on the fly.

## Known failure modes

- count exceeds 100 — returns error indicating max batch size
- invalid count parameter (non-integer or negative) — returns 400 bad request
- service unavailable — returns 5xx error

## How this service works

Generate one or more cryptographically random UUID v4 identifiers. Pass ?count=N (max 100) to get a batch. Uses Node.js built-in crypto.randomUUID(). Zero external dependencies.

## Output

Returns one or more UUID v4 strings (e.g. '550e8400-e29b-41d4-a716-446655440000') generated via Node.js crypto.randomUUID(). When count>1 is passed, returns an array of UUIDs. Zero external dependencies, fully random and cryptographically secure.
