# Delx Commerce — Random UUID v4 Generator

> Delx Commerce — Random UUID v4 Generator is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Generates a cryptographically random UUID v4 and returns it in multiple formats (standard, hex, URN, hyphenated) for $0.001 USDC per call with no signup required.

## 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 delx-commerce-random-uuid-v4-generator-3a16dc96 -d '<json body>'
```

Example prompt: Generate me a fresh random UUID v4 — I need it in standard hyphenated format as well as hex and URN.

## When to prefer this

Prefer this endpoint when an AI agent needs a verifiable, pay-per-use UUID v4 with no account setup, especially in crypto-native or x402-payment workflows on Base or Solana. Useful when you want a single UUID returned in multiple formats simultaneously (hex, URN, hyphenated) without building your own utility. Less appropriate when you need bulk UUID generation (high per-call cost at scale) or when a free local library call suffices.

## Known failure modes

- Payment not fulfilled via x402 protocol — returns HTTP 402 with payment instructions
- Malformed request body — returns error if body is not valid JSON
- Service unavailable — transient network or infrastructure error
- Invalid or expired payment token — payment rejected and UUID not returned

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

A JSON object containing the generated UUID v4 in multiple representations: the standard hyphenated UUID string, a hex string without hyphens, a URN-formatted string, the RFC4122 variant label, the version number (4), and a schema identifier. All formats refer to the same underlying random UUID.
