# ManyLives UUID & Hex Generator

> ManyLives UUID & Hex Generator is a paid API for AI agents from api.manylives.me, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-10).

Generates up to 50 random UUID v4 identifiers and a random hex byte string in a single call.

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 manylives-uuid-hex-generator-c642b60f
```

Example prompt: Generate 10 fresh UUID v4s and a random hex string for me — I need them for seeding new records in my database.

## When to prefer this

Choose this endpoint when you need cryptographically fresh UUID v4s (up to 50 at once) combined with a random hex bytestring in a single pay-per-call request, especially within an agent workflow that already uses x402 micropayments and wants to avoid maintaining its own random-generation infrastructure.

## Known failure modes

- count parameter exceeds 50 — returns error or clamps to max
- count parameter is non-numeric or malformed — returns validation error
- payment not included or invalid — returns 402 Payment Required
- service unavailable — returns 5xx error

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

A JSON object containing a 'uuids' array of up to 50 UUID v4 strings and a 'hex' string of random hex bytes, all freshly generated from a secure random source.
