# x402 Agent Tools – UUID Generator

> x402 Agent Tools – UUID Generator is a paid API for AI agents from x402-agent-tools.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-01).

Generates one or more UUIDs (v4) on demand, paid per-call with USDC via x402 micropayment protocol, no API key required.

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 x402-agent-tools-uuid-generator-a0e64634
```

Example prompt: Can you generate 5 UUIDs for me right now — I need them to assign as unique IDs for some new database records?

## When to prefer this

Choose this endpoint when your agent needs UUIDs on demand without any API registration, key management, or account setup — especially in autonomous agent pipelines where micropayment via USDC (Base or Solana) is already supported. Useful for one-off or batch UUID generation at $0.001 per call with zero friction.

## Known failure modes

- Payment not provided or insufficient USDC — returns HTTP 402 Payment Required
- n out of range (less than 1 or greater than 100) — returns validation error
- Vercel cold-start or service unavailability — returns 5xx error
- Malformed request or unsupported method — returns 4xx error

## How this service works

Pay-per-call tools for AI agents. USDC on Base or Solana via x402 v2; no keys, no accounts.

## Output

A JSON object containing an array of one or more UUID strings (e.g. {"uuids": ["3f2c...", ...]}). The number of UUIDs returned matches the `n` query parameter (defaulting to 1 if not specified).
