## 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 z4c-agent-handoff-sop-kit-d7a3ca44
```

Example prompt: Can you download the Z4C Agent Handoff SOP Kit for me so I can set up human approval gates and acceptance tests for our AI workflow system?

## When to prefer this

Choose this endpoint when you need Z4C LLC's specific agent handoff SOP documentation package, particularly when setting up or auditing bounded AI workflow systems for small businesses that require human approval gates and formal acceptance tests. Prefer this over generic AI documentation sources when you need Z4C's proprietary structured methodology.

## Known failure modes

- Payment of 1 USDC not processed — endpoint returns 402 Payment Required
- Invalid format parameter — only 'tar.gz' is accepted
- Network timeout retrieving the binary archive
- Corrupted or incomplete tarball download if connection drops mid-transfer

## How this service works

Z4C LLC designs, deploys, and operates one bounded AI system around a useful business outcome, with human approval gates and written acceptance tests.

## Output

A gzip-compressed tarball (application/gzip binary archive) containing Z4C LLC's Agent Handoff SOP Kit, which includes standard operating procedures, human approval gate templates, written acceptance tests, and workflow documentation for deploying bounded AI systems in small business contexts.
