## 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 datavault-random-string-generator-fd6446b8 -d '<json body>'
```

Example prompt: Generate a random string that is 32 characters long using hex encoding.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call random string generation without setting up your own RNG infrastructure. Useful for generating tokens, nonces, session IDs, or test data on demand with configurable length and encoding.

## Known failure modes

- Invalid encoding type specified — returns error or unexpected output
- Length parameter missing or zero — may return empty or error
- Payment not completed — 402 response blocking access
- Server-side generation failure — success: false with no data
