Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 defi-yield-and-looping-comparator-f974e8cb
```

Example prompt: Can you compare the current yield opportunities on Kamino Lend and Aave V3 for me, and also model what a manual lending loop would look like if I were to recurse through a few borrow-and-deposit cycles?

## When to prefer this

Use this endpoint when you need to compare DeFi lending yields specifically between Kamino Lend (Solana) and Aave V3 (Ethereum/EVM) and want to model leveraged looping strategies without executing any on-chain transactions. Prefer this over generic DeFi aggregators when you need side-by-side lending loop simulations.

## Known failure modes

- Upstream protocol data unavailable — returns stale or empty yield data
- Rate limit or payment failure — returns 402 or 429 error
- Protocol-specific outage on Kamino or Aave — partial data returned
- Invalid query parameters — returns validation error

## How this service works

Compare DeFi yield opportunities and model manual lending loops on Kamino Lend and Aave V3.

## Output

Returns a comparison of current DeFi yield opportunities across Kamino Lend and Aave V3, including APY rates and a modeled breakdown of manual lending loop strategies showing projected returns across recursive borrow-and-deposit cycles.
