## 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-85008c46
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC right now — I want to see APYs, TVL depth, and yield spreads across Base, Arbitrum, Solana, and Ethereum so I can decide where to deploy my capital.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset and want risk-adjusted APY comparisons across multiple protocols and chains (Base, Arbitrum, Solana, Ethereum) sourced from DeFiLlama. Prefer it over generic crypto price APIs when the goal is yield optimization or liquidity pool selection rather than spot price lookup.

## Known failure modes

- Missing or empty 'asset' parameter returns a 400 validation error
- Unknown or unsupported asset symbol returns an empty result set or error
- DeFiLlama data unavailability may cause stale or incomplete APY data
- Rate limiting or payment failure (402) if x402 micropayment is not properly handled
- Network timeout if upstream DeFiLlama API is slow or unresponsive
