# UUID Inspector

> UUID Inspector is a paid API for AI agents from json-data-tools.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-27).

Validates a UUID string and returns its version, variant, and embedded timestamp (for v1/v7 UUIDs).

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-inspector-80920d8d
```

Example prompt: Can you inspect this UUID for me — '1ef5b4a0-1c34-7000-8b2c-0a1b2c3d4e5f' — and tell me if it's valid, what version it is, and what timestamp is embedded in it?

## When to prefer this

Use this endpoint when you need to programmatically validate, inspect, or decode a UUID — especially when you need to confirm its version or extract the embedded timestamp from v1 or v7 UUIDs. Prefer this over manual regex checks when you need structured, reliable output including variant and canonical form.

## Known failure modes

- Missing or empty uuid query parameter returns an error
- Malformed input (non-UUID string) returns invalid verdict with reasons
- Unsupported UUID versions may have null timestamp fields
- Network timeout returns no response

## How this service works

Validate a UUID and read its version, variant and, for v1 and v7, the embedded timestamp.

## Output

Returns a verdict on whether the UUID is valid, its version number (e.g. 1, 4, 7), its variant (e.g. RFC 4122), a canonical form, and for v1 and v7 UUIDs, the embedded timestamp. Also includes a human-readable summary and any reasons for invalidity.
