## 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-yields-intelligence-api-47ad5c5b
```

Example prompt: What are the best DeFi yield opportunities available right now, especially for stablecoins like USDC? I want to see APYs ranked across different protocols.

## When to prefer this

Choose this endpoint when you need up-to-date, AI-curated DeFi yield intelligence without setting up an API key — ideal for agents that pay per-call with USDC on Base via x402. Prefer this over generic DeFi aggregators when you want intelligence-layer ranking and filtering rather than raw protocol data dumps.

## Known failure modes

- Payment not included or insufficient USDC balance returns HTTP 402 Payment Required
- Invalid or malformed property filters return 400 Bad Request
- Data may be delayed if on-chain indexing is lagging
- No results returned if queried asset/protocol has no current yield data
- Rate limits may apply per wallet address

## 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

Returns a list of DeFi yield opportunities including protocol names, asset pairs, APY/APR rates, liquidity depth, and chain information, curated and ranked by an AI-powered intelligence layer.
