## 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-best-yields-by-asset-0252666a
```

Example prompt: What's the best DeFi yield available for USDC right now — which protocol is paying the highest APY?

## When to prefer this

Use this endpoint when an agent needs to find the single best or top-ranked DeFi yield for a specific token or asset. Prefer it over generic DeFi aggregators when you need a quick, programmatic, pay-per-call lookup without API key management, using the x402 USDC micropayment protocol on Base.

## Known failure modes

- Unknown or unsupported asset symbol returns an error or empty result
- Asset with no active yield pools returns empty data
- Payment failure via x402 protocol results in 402 response before data is returned
- Stale yield data if protocols have not been recently indexed
- Rate limiting or service unavailability on the Vercel deployment
