# SignalDesk AI UUID Inspector

> SignalDesk AI UUID Inspector is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Parses and inspects a UUID string, returning its version, RFC variant compliance, nil status, and syntax validity

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 signaldesk-ai-uuid-inspector-9bfc3989 -d '<json body>'
```

Example prompt: Can you inspect this UUID for me — '550e8400-e29b-41d4-a716-446655440000' — and tell me what version it is, whether it's RFC-compliant, and if the syntax is valid?

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.001 USDC) programmatic check on a UUID string to determine its version, RFC compliance, nil status, and syntactic validity — especially in agent workflows that handle user-submitted IDs, database keys, or third-party API tokens that must conform to specific UUID standards.

## Known failure modes

- Invalid or missing 'uuid' field returns an error response
- String longer than 36 characters may be rejected
- Malformed JSON body causes a 400-level error
- Non-UUID strings (e.g. plain strings, integers) may return valid_syntax: false rather than an error

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object indicating: whether the UUID is nil (boolean), the UUID version number (integer), whether it conforms to the RFC variant (boolean), and whether the syntax is valid (boolean).
