# NovaPath Next Teaching Move Selector

> NovaPath Next Teaching Move Selector is a paid API for AI agents from instructional-decision-engine-x402.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-31).

Selects a bounded, grade-appropriate (3-8) instructional teaching move based on observed student error patterns, prior instruction, and available time.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-next-teaching-move-selector-e496bef3 -d '<json body>'
```

Example prompt: I'm teaching 5th grade fraction addition and most students are adding denominators instead of finding common denominators — I just finished a worked example and have about 10 minutes left. The error came up on an exit ticket. What teaching move should I do next?

## When to prefer this

Use this endpoint when a teacher or instructional agent needs a structured, bounded next teaching move grounded in an observed student error pattern and remaining class time — specifically for grades 3-8 math and literacy skills enumerated in the schema. Prefer this over generic LLM-generated instructional advice when authored, reviewed decision logic is required and no efficacy claims should be made.

## Known failure modes

- Invalid grade outside 3-8 range returns validation error
- Unsupported skill enum value causes request rejection
- minutes value outside 4-20 range is rejected
- Unknown or missing required fields may result in incomplete decision output
- Edge combinations of errorPattern and skill with no authored logic may return limited guidance

## How this service works

Select a bounded grade 3-8 teaching move, practice and check for supported error patterns. Authored guidance; historical content owner-reviewed; bounded authored decision logic; no efficacy claim.

## Output

A recommended, bounded teaching move from the authored decision logic — such as error analysis, visual model, guided practice, or worked example — appropriate to the specified grade, skill, error pattern, prevalence, and available time, with supporting instructional guidance. No efficacy claims are made.
