## 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 vextorium-aave-v3-live-rates-cc2399df -d '<json body>'
```

Example prompt: What are the current Aave v3 lending and borrowing APYs for the main assets on Base right now?

## When to prefer this

Use this endpoint when you need a quick, low-cost snapshot of live Aave v3 lending and borrowing APYs for the most liquid assets on a specific EVM chain. Prefer this over the full-market endpoint when you only need rates for the main assets (WETH, USDC, USDT, DAI, cbBTC/WBTC) and don't require TVL or incentive breakdowns. Choose the cross-chain comparison sibling endpoint if you need to compare the same asset across all networks simultaneously.

## Known failure modes

- Invalid or unsupported network value returns an error
- Network connectivity or on-chain RPC issues may cause timeouts
- Missing required 'network' field in body defaults to 'base' but malformed JSON causes a 400 error
- If Aave v3 is not deployed on the requested network, an empty or null markets list may be returned
