## 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 supertutor-explain-it-e051749b -d '<json body>'
```

Example prompt: Can you explain how neural networks work as if I'm a curious high schooler who knows basic algebra but has never coded before?

## When to prefer this

Choose this endpoint when you need dynamically leveled explanations of arbitrary concepts — especially when the audience's background varies widely and a one-size-fits-all explanation won't work. It is ideal for tutoring agents, educational chatbots, or any workflow where the same concept must be re-explained to users with different expertise levels without manual rewriting.

## Known failure modes

- Empty or missing 'input' field returns a validation error
- Input exceeding 8000 characters is rejected
- Ambiguous level description may produce a mismatched explanation depth
- Payment failure on the x402 layer results in no response
- Overly vague concept may yield a generic explanation
