## 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-v1-validator-d28265a0 -d '<json body>'
```

Example prompt: Is '6ba7b810-9dad-11d1-80b4-00c04fd430c8' a valid UUID v1?

## When to prefer this

Use this endpoint when you need a fast, deterministic, no-network UUID v1 format check without spinning up your own regex logic. Prefer the free sandbox endpoint (/v1/sandbox/id-uuid-v1) for testing. Choose this paid endpoint when operating in production where reliability and guaranteed response are needed.

## Known failure modes

- Empty string input returns an error (minLength: 1 enforced)
- Non-string value passed as 'value' field may be rejected
- Payment failure (402) if x402 payment not attached; use sandbox endpoint to test for free
- Malformed request body returns a 4xx error

## How this service works

Call when an agent needs whether a string is a valid uuid-v1. No network. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/id-uuid-v1 first.

## Output

A validation result indicating whether the provided string conforms to the UUID v1 format specification, returned as a boolean or structured response indicating validity.
