## 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-topic-search-16f7075f -d '<json body>'

Example prompt: Search the SperaxOS Academy for topics about staking so I can learn how it works in DeFi.

## When to prefer this

Use this endpoint when you need to find DeFi educational content specifically within the SperaxOS Academy ecosystem, particularly for topics related to Sperax, USDs stablecoin, or general DeFi concepts taught through their platform. Prefer this over general web search when the user wants curated, structured academy-style educational content from Sperax rather than arbitrary web results.

## Known failure modes

- No matching topics found for obscure or misspelled queries — returns empty results
- Payment failure if USDC balance on Base is insufficient for the $0.001 per-call fee
- Malformed request if query field is missing or not a string
- Rate limiting or service unavailability during high load

## 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

A list of matching academy topics from the SperaxOS DeFi education platform, each likely including topic titles and relevant descriptive content that match the provided search keyword or phrase.
