## 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 24k-labs-eli5-explainer-78a89cae -d '<json body>'
```

Example prompt: Can you give me an ELI5 explanation of how the x402 payment protocol works — something a total beginner could understand?

## When to prefer this

Choose this endpoint when you need to convert a complex, technical, or jargon-heavy concept into a simple beginner-friendly explanation in one call, especially within the x402 micropayment ecosystem where per-call pricing is acceptable. Prefer it over general LLM prompting when you want a standardized, consistent ELI5 output format with a predictable response schema.

## Known failure modes

- Missing or empty input topic returns an error or generic fallback response
- Overly vague prompts may produce shallow or off-topic explanations
- Payment failure (insufficient USDC balance) results in 402 response before processing
- Rate limiting may occur under high request volume
- Very long or compound inputs may produce truncated or fragmented explanations
