## 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 gadgethumans-uuid-generator-f7080ebd
```

Example prompt: Can you generate 5 fresh UUID v4 identifiers for me to use as unique keys in my test fixtures?

## When to prefer this

Choose this endpoint when you need one or more cryptographically random UUID v4 identifiers instantly without standing up your own UUID generation service. Particularly useful in agentic workflows where you need unique keys for database records, request correlation, fixture generation, or distributed system coordination and want a simple REST call rather than importing a library.

## Known failure modes

- Invalid or missing count parameter may return an error or default to 1 UUID
- Requesting an extremely large count may be rejected or throttled
- Payment failure (x402) if USDC balance is insufficient — returns 402 status
- Network timeout if the service is temporarily unavailable

## How this service works

Generate fresh random UUID v4 identifiers, one or many in a single call. Cryptographically random, instant. Use for unique ids, request keys or fixtures.

## Output

Returns a JSON object containing the count of UUIDs requested and an array of UUID v4 strings (e.g. {"count":1,"uuids":["e7de7957-baf9-468f-874b-2e3be1f2df23"]}). Each UUID is a cryptographically random, standards-compliant v4 identifier.
