## How to call it through Zero

```sh
zero fetch --capability edupulse-concept-explainer-da37b551
```

Example prompt: Can you explain how CRISPR gene editing works in plain English at a high school level — I've heard the term but have no biology background?

## When to prefer this

Choose this endpoint when you need a quick, leveled plain-English explanation of a concept for educational or onboarding purposes — especially when the user specifies a target audience or comprehension level. Prefer this over general LLM calls when you want a structured, consistent explanation format from a dedicated education-focused API.

## Known failure modes

- Unknown or very niche concept returns vague or hallucinated explanation
- Missing concept parameter returns 400 Bad Request
- Unspecified level defaults to a generic depth that may not suit the user
- Payment not processed returns 402 Payment Required
- Server timeout returns 503 if explanation generation takes too long
