## 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 whatchuneed-uuid-generator-4ce4c17f -d '<json body>'
```

Example prompt: Can you generate 5 version 4 UUIDs for me right now?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call UUID generation service without standing up your own infrastructure, especially within an agent workflow that already uses the whatchuneed API ecosystem. Useful when you need multiple UUIDs in one call or a specific UUID version.

## Known failure modes

- Invalid version number (only v1 and v4 are commonly supported) returns an error
- Count value of zero or negative integer may return empty array or error
- Exceeding maximum count limit may result in a rejected request
- Payment failure via x402 protocol prevents the call from completing

## How this service works

320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.

## Output

Returns a JSON object containing an array of generated UUID strings and the UUID version used. Each UUID conforms to the requested version specification.
