## 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 training-lesson-paragraph-change-report-b93b535e -d '<json body>'

Example prompt: Compare my updated training lesson against the previous draft and give me a paragraph change report — here's the new version: '## Objectives
Students will learn core concepts.
## Lesson
This section covers advanced topics.
## Exercise
Complete the worksheet.' and the old version was '## Objectives
Earlier supplied content.'

## When to prefer this

Choose this endpoint when you need a deterministic, reproducible paragraph-level change report specifically for training lesson documents formatted in Markdown or plain text. It is ideal when you do not need generative AI commentary or fact-checking — just a structured diff of what changed paragraph by paragraph. Prefer this over generic diff tools when working within the datapackvibe assistant-sector writing pipeline and when cost predictability ($0.01 per call) matters.

## Known failure modes

- Missing or empty text field — report cannot be generated
- previous_text not provided — comparison may default to empty baseline
