## 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 nwb-vending-scope-creep-say-no-boundary-rubric-mf-tool-003-c08e4496 -d '<json body>'
```

Example prompt: Pull up the scope creep say-no rubric from NWB Vending's Materials Factory — I need the boundary rules so I can figure out whether this client's new request falls outside our original agreement.

## When to prefer this

Choose this endpoint when you need a pre-built, agent-ready decision rubric specifically for scope creep and client boundary-setting in small business / contractor contexts, rather than prompting an LLM to generate ad hoc rules. Particularly useful in agentic workflows that need a stable, versioned artifact to apply consistently across client interactions.

## Known failure modes

- Wrong or missing pack_id returns an unrelated or empty artifact
- Payment failure (402) if x402 funds are unavailable
- Endpoint downtime returns a 5xx error with no rubric data
- Schema mismatch if the version field changes and downstream agent logic breaks
