## 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 retainer-ongoing-service-client-agent-pack-mf-tpl-045-ef51ee07 -d '<json body>'
```

Example prompt: Pull up the Materials Factory retainer and ongoing service client playbook so I can set up automated communications and workflows for my long-term retainer clients.

## When to prefer this

Choose this endpoint when an AI agent needs ready-made, structured templates and playbooks specifically for retainer or ongoing service clients — covering recurring billing, status updates, and long-term relationship management — rather than one-off project or transactional client workflows.
