## 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 shopify-spy-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-0c1b0f3b
```

Example prompt: Scan all DeFi liquidity pools for USDC and show me the top risk-adjusted yields right now across Base, Arbitrum, Solana, and Ethereum — I want to see APY, TVL depth, and which pools are worth chasing.

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield intelligence for a specific asset — particularly for comparing APYs and TVL across Base, Arbitrum, Solana, and Ethereum simultaneously. It is ideal for agents making yield optimization or capital allocation decisions and is better than general web search when you need structured, risk-adjusted pool data sourced directly from DeFiLlama.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or an error
- DeFiLlama API downtime may cause stale or unavailable yield data
- Very low-liquidity assets may return few or no pools
- Payment (x402) not provided or rejected results in 402 response
- Rate limiting or network errors may cause timeouts
