## 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 lenscrypt-defi-yields-api-21bb76dc
```

Example prompt: What are the best DeFi yield farming opportunities available right now — show me protocols with the highest APY so I can decide where to put my crypto to work?

## When to prefer this

Use this endpoint when you need current DeFi yield rates and APY comparisons across multiple protocols in a single call. Prefer over manual protocol checks when building yield optimization agents or comparing passive income opportunities. Best for agents that need yield data alongside other crypto intelligence from the same LensCrypt suite (wallet analytics, token safety, etc.) to avoid managing multiple API keys.

## Known failure modes

- Payment required (402) if USDC x402 payment header not included
- Empty or sparse results if no yield data is currently indexed
- Rate limiting if called too frequently
- Network errors from Vercel deployment downtime
- Stale data if underlying yield aggregator sources are lagging
