## 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-defi-research-api-03daf2e4
```

Example prompt: Can you pull up AI-powered DeFi research on the Sperax USDs stablecoin protocol — I want to understand its yield mechanics, risks, and current market position?

## When to prefer this

Choose this endpoint when you need AI-generated DeFi intelligence on a specific protocol, token, or market question without managing API keys — ideal for autonomous agents that can pay per-request in USDC on Base. Prefer this over generic web search when you need synthesized, DeFi-specific analysis rather than raw data scraping.

## Known failure modes

- Payment failure if USDC balance on Base is insufficient (402 response)
- Malformed or missing query parameter returns 400 error
- Unknown or unsupported protocol/token returns empty or low-confidence result
- Network congestion on Base delays payment settlement
- Rate limiting if too many rapid requests from same wallet

## 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-synthesized DeFi research response covering the queried protocol, token, or market topic — likely including protocol mechanics, yield rates, risk factors, market data, and analytical commentary, returned as structured or semi-structured data.
