## 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-v7-validator-cff7c75b -d '<json body>'
```

Example prompt: Can you check if this string is a valid UUID v7: '018f4e3a-1b2c-7d4e-9f0a-1b2c3d4e5f6a'?

## When to prefer this

Use this endpoint when you need deterministic, spec-compliant UUID v7 validation without relying on local libraries or when operating in an environment where you want an authoritative external check. Prefer the free sandbox endpoint POST /v1/sandbox/id-uuid-v7 first; use this paid endpoint ($0.008 USDC) when the sandbox is unavailable or when you need guaranteed SLA.

## Known failure modes

- Empty or missing value field returns an error
- Value exceeding 20,000 characters is rejected
- Malformed request body returns 400-level error
- Payment failure prevents endpoint access

## How this service works

Call when an agent needs whether a string is a valid uuid-v7. No network. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/id-uuid-v7 first.

## Output

Returns a validation result indicating whether the provided string is a valid UUID version 7, including a boolean pass/fail and potentially details about why it failed format checks.
