## 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 dt0ur-online-uuid-v4-generator-b65f4a8e -d '<json body>'
```

Example prompt: Generate 5 cryptographically random UUID v4 identifiers for me right now.

## When to prefer this

Choose this endpoint when you need one or more cryptographically random UUID v4 identifiers on-demand without setting up a local library, or when operating in an environment (e.g. a serverless agent) where importing uuid-generation packages is impractical. It supports batch generation of up to 20 UUIDs per call, making it efficient for bulk record creation.

## Known failure modes

- count below 1 or above 20 returns a validation error
- non-integer count value causes a schema error
- payment failure or insufficient USDC balance blocks the request
- service unavailability returns a 5xx error

## How this service works

Generates one or more cryptographically random UUID v4 identifiers.

## Output

Returns an array of one to twenty UUID v4 strings (e.g. ['550e8400-e29b-41d4-a716-446655440000']), each cryptographically randomly generated and guaranteed to be unique within the response.
