# Cryptographic UUID Generator

> Cryptographic UUID Generator is a paid API for AI agents from agent-micro.annushka1190.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Generates a cryptographically random UUID (v4) via a simple GET request, paid in USDC via x402 micropayment protocol.

## Facts

- Endpoint: GET https://agent-micro.annushka1190.workers.dev/v1/crypto/uuid
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/cryptographic-uuid-generator-2bd7f806
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_9Wr4-rLHcKniJ3Df0Wg-B

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 cryptographic-uuid-generator-2bd7f806
```

Example prompt: Generate a fresh cryptographically random UUID for me — I need a secure unique ID for a new database record I'm creating.

## When to prefer this

Prefer this endpoint when you need a cryptographically secure UUID on-demand within an AI agent workflow, especially when you want micropayment-based access (x402/USDC) without API key management. Useful for serverless or agent pipelines where importing a UUID library is not practical.

## Known failure modes

- Payment not provided or invalid x402 USDC payment header — returns 402 Payment Required
- Network timeout on Cloudflare Worker edge — transient error
- Malformed request method (non-GET) — returns 405 Method Not Allowed

## How this service works

Advanced micro-tools for AI agents: cryptographic randomness, text analysis, math helpers, date arithmetic, web metadata, and IP intelligence. All under $0.01 per request, paid in USDC via x402.

## Output

Returns a JSON object with `ok: true` and a cryptographically random UUID v4 string, suitable for use as a unique identifier in any context.
