## 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 edupulse-exam-grader-84b27bba
```

Example prompt: Can you grade this bar exam practice essay I wrote on negligence — score it using a rubric and give me detailed feedback on what I got right and where I lost points?

## When to prefer this

Use this endpoint when an AI agent or student needs rubric-aligned scoring and detailed written feedback on a practice exam response, especially for high-stakes professional exams like the bar or CPA. Prefer this over generic essay reviewers when structured, format-specific scoring (bar/CPA) is required.

## Known failure modes

- Missing or empty exam response body returns error
- Unsupported exam format type returns validation error
- Ambiguous or missing rubric context may reduce scoring accuracy
- Overly short responses may receive minimal feedback
- Request without valid x402 payment header returns 402 Payment Required
