Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 24k-labs-eli5-concept-explainer-5b4f4469 -d '<json body>'

## When to prefer this

Choose this endpoint when you need a concise, beginner-accessible explanation of a concept rather than a detailed technical breakdown. It is ideal for onboarding, education, content creation for general audiences, or any situation where jargon must be removed. Prefer this over a general LLM call when you want a consistently scoped, cost-controlled, pay-per-use simplification service.

## Known failure modes

- Empty or missing concept input returns a validation error
- Extremely vague topics may produce overly generic explanations
- Very niche or newly coined terms may be explained with limited accuracy
- Rate limiting or payment failure via x402 protocol returns a 402 response
