## 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-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-0db4d9c0
```

Example prompt: Can you scan the top risk-adjusted DeFi yield pools for USDC right now — I want to see the best APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum?

## When to prefer this

Use this endpoint when you need real-time, cross-chain DeFi yield data for a specific asset and want risk-adjusted APY comparisons rather than raw rates. Prefer this over manual DeFiLlama browsing when automating yield optimization decisions or building DeFi agent workflows that need structured, ranked pool data across multiple chains in a single call.

## Known failure modes

- Unknown or unsupported asset symbol returns empty or error response
- DeFiLlama upstream API unavailability causes stale or missing data
- Misspelled asset symbol (e.g. 'USDT' vs 'USDC') returns wrong asset pools
- Payment not processed (402) if x402 USDC payment is not included
- Thin TVL pools may appear with inflated APYs that are misleading without context

## How this service works

## Output
