## 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 physical-sample-color-proof-approval-agent-pack-mf-tpl-043-2d705bb9 -d '<json body>'
```

Example prompt: Pull up the Materials Factory physical sample and color proof approval playbook so I can run the client sign-off workflow for this print job.

## When to prefer this

Use this endpoint when you need a structured, ready-made agent workflow for managing physical sample or color proof approvals in print, signage, or manufacturing contexts — specifically when you want pre-built communication scripts and task definitions rather than building a custom approval flow from scratch. Prefer this over generic project management templates when the workflow involves physical artifacts requiring client sign-off before production proceeds.

## Known failure modes

- 404 if the pack_id does not exist or endpoint path changes
- 402 Payment Required if USDC micropayment not processed
