## 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-e473d46f -d '<json body>'
```

Example prompt: Scan all live DeFi pools for USDC and show me the top risk-adjusted yields across Base, Arbitrum, Solana, and Ethereum — I want to see APY, TVL, and how they compare.

## When to prefer this

Use this endpoint when you need live, cross-chain DeFi yield comparison for a specific asset and want risk-adjusted APY and TVL data aggregated from DeFiLlama in a single call. Prefer this over manual DeFiLlama browsing when an agent needs to programmatically rank yield opportunities across Base, Arbitrum, Solana, and Ethereum without building a custom scraper.

## Known failure modes

- Unknown or unsupported asset symbol returns an error or empty pool list
- DeFiLlama upstream data unavailable causes stale or missing APY data
- Asset symbol too short or malformed triggers validation error (minLength:1)
- Low TVL pools may appear with unreliable or outlier APY figures
- Rate limiting or payment failure (402) if USDC micropayment not processed
