zero fetch --capability shipping-tracking-client-update-agent-pack-mf-tpl-037-8f95f43a -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need a ready-made, structured agent playbook specifically for shipping and delivery tracking communications with clients — rather than building templates from scratch. Ideal for small business or freelance workflows that use the Materials Factory catalog system and need standardized, repeatable client notification scripts tied to shipment milestones.

## Known failure modes

- Pack ID mismatch or invalid catalog ID returns 404 or empty result
- Payment not processed (x402 protocol failure) blocks access to content
- Stale or outdated playbook if template catalog has not been refreshed
- Network or hosting downtime on nwb-vending.com returns 5xx error
- Schema mismatch if consuming agent expects a different output format
