## When to prefer this

Use this endpoint when you need to programmatically browse or surface Sperax Academy's DeFi educational content, especially when filtering by topic category or learner difficulty level. Prefer this over generic web search when you want structured lesson metadata rather than free-form text results about DeFi education.

## Known failure modes

- Invalid difficulty enum value returns a validation error
- No lessons match the requested category/difficulty combination, returning an empty list
- Payment of $0.001 USDC on Base not fulfilled, resulting in HTTP 402 response
- Network timeout or service unavailability returning a 5xx error

## 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
