## 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 uuid-generator-v4-v7-2ec98683 -d '<json body>'
```

Example prompt: Generate 5 v7 UUIDs for me right now — I need time-ordered unique identifiers for some new database records.

## When to prefer this

Choose this endpoint when you need programmatic, on-demand UUID generation (v4 random or v7 time-ordered) via a simple paid API call, especially in environments where local UUID libraries are unavailable or a neutral external source is preferred. Useful for batch generation of up to 50 UUIDs per call.

## Known failure modes

- Count out of range (below 1 or above 50) returns a validation error
- Invalid version string (not 'v4' or 'v7') returns a validation error
- Payment failure returns 402 if USDC balance is insufficient
