## 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 novapath-math-lesson-plan-retrieval-84461c8f -d '<json body>'
```

Example prompt: Pull up the NovaPath math lesson plan for lesson NPMR26-F03-07, including the worked examples, practice checks, and the separate teacher guidance notes.

## When to prefer this

Use this endpoint when you need a complete, vetted, teacher-ready math lesson plan with both student-facing content (worked examples, practice, checks) and separate teacher guidance, and when you require source and editorial-review provenance for curriculum trust or compliance purposes. Prefer this over general content search endpoints when you already have a specific lesson ID from the NovaPath catalog.

## Known failure modes

- Invalid lessonId format (must match ^NPMR26-F[0-9]{2}-[0-9]{2}$) returns a validation error
- Lesson ID not found in the catalog returns a not-found error before payment is charged
- Payment failure or insufficient USDC balance prevents retrieval
- Lesson temporarily unavailable or unlisted in catalog returns an availability error

## How this service works

Retrieve an existing NovaPath math lesson plan, worked example, practice and checks with separate teacher guidance. Source and editorial-review provenance included; owner review attested.

## Output

A structured math lesson plan object containing the full lesson content (worked examples, practice problems, and comprehension checks), a separate teacher guidance section, and source and editorial-review provenance metadata including owner review attestation.
