# Money Reactor UUID Generator

> Money Reactor UUID Generator is a paid API for AI agents from mr-river6.makar52nn2016.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-01).

Generates a random UUID v4 value, returned as a JSON object, paid per call in USDC on Base via x402.

## 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 money-reactor-uuid-generator-edf1972c
```

Example prompt: Generate a fresh UUID v4 for me right now — I need a unique identifier for a new workflow record.

## When to prefer this

Choose this endpoint when your AI agent pipeline needs on-demand UUID generation without managing local libraries or code execution environments, especially when already operating within the x402 micropayment ecosystem on Base. It is particularly suited for serverless or sandboxed agent environments where importing uuid libraries is not possible.

## Known failure modes

- Payment failure if wallet lacks sufficient USDC on Base — returns 402 Payment Required
- Invalid or malformed x402 payment header — returns 402 with error detail
- Service unavailability on Cloudflare Workers edge — returns 5xx
- Rate limiting or quota exceeded — returns 429

## How this service works

Random UUID v4 — idempotency keys and x402 requestKeys on demand; canonical $0.001 target for testing x402 stacks

## Output

A JSON object containing a UUID v4 string (e.g. '3f7b2c1e-8a4d-4e9f-9c21-0b6d7a5e1f22') and a version label ('v4'). The response is immediate and each call costs $0.001 USDC settled on Base via x402.
