## 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 speraxos-academy-learn-topic-81248964 -d '<json body>'
```

Example prompt: Can you explain impermanent loss to me at a beginner level — I'm new to DeFi and want simple analogies, not technical jargon?

## When to prefer this

Choose this endpoint when you need on-demand, difficulty-adjusted educational explanations of DeFi and crypto concepts without managing API keys. It is especially well-suited for AI agents that need to answer user questions about DeFi topics inline, onboard new users to Web3 concepts, or provide contextual education within a DeFi product. It excels over generic LLM prompting when you want a curated, DeFi-specialized response with pay-per-use micro-payment pricing via x402 USDC on Base.

## Known failure modes

- Unrecognized or off-topic topic string may produce a generic or low-quality response
- Missing topic field returns a validation error
- Invalid difficulty enum value returns a 422 or similar input error
- Payment failure via x402 protocol results in a 402 Payment Required response before the explanation is generated
- Rate limiting or service unavailability returns a 503 or timeout

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

An AI-generated educational explanation of the requested DeFi or crypto topic, tailored to the specified difficulty level. Beginner responses use plain-language analogies, intermediate responses include technical details, and advanced responses cover protocol-level mechanics. The response is a structured text explanation suitable for displaying directly to a user or incorporating into an educational workflow.
