## 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 delx-commerce-nonce-hex-generator-4f723642 -d '<json body>'
```

Example prompt: Generate a random 8-byte nonce as a hex string for me to use in my signing workflow.

## When to prefer this

Choose this endpoint when you need a verifiably delivered, pay-per-use random nonce in hex format with no API key or account required — especially useful in agent workflows on Base or Solana that already handle x402 micropayments and need cryptographic randomness on demand.

## Known failure modes

- Invalid or missing 'bytes' field returns an error
- Zero or negative byte count may be rejected
- Extremely large byte values may be rejected or rate-limited
- Payment failure via x402 protocol results in 402 response and no nonce returned

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

A JSON object containing the hex-encoded nonce string (e.g. 'd9903033aec23a97'), the number of bytes generated, and a schema version identifier ('delx/util-nonce-hex/v1').
