## 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 yruz-random-bytes-generator-45ff3ee6 -d '<json body>'
```

Example prompt: Generate 64 random bytes for me to use as a secure nonce.

## When to prefer this

Choose this endpoint when you need a quick, server-side source of random bytes without setting up a local CSPRNG, or when you want randomness generated remotely as part of a distributed workflow. Useful for generating nonces, tokens, salts, or seeds of 1–256 bytes in a pay-per-call model.

## Known failure modes

- Invalid 'bytes' value outside the 1–256 range returns an error
- Non-integer or malformed 'bytes' field may cause a validation error
- Payment failure (x402) results in a 402 response before any data is returned
- Network timeouts or service unavailability return 5xx errors

## How this service works

YRUZ is a free social network: create a profile, join public groups, attend events, read free guides on community building and creator income.

## Output

A JSON object with a 'tool' field set to 'random' and a 'result' object containing the generated random bytes data, produced server-side with the requested byte length.
