## 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 hn-pulse-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-arbitrage-31d4b965 -d '<json body>'
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC across Base, Arbitrum, Solana, and Ethereum and show me the best APYs with TVL depth so I can decide where to deploy capital.

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield intelligence for a specific asset — particularly when comparing risk-adjusted APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer it over manual DeFiLlama browsing or single-chain tools when an agent needs to programmatically identify yield arbitrage opportunities or rank pools for capital deployment decisions.

## Known failure modes

- Invalid or unrecognized asset symbol returns an error or empty result set
- DeFiLlama API unavailability causes stale or missing data
- Very low-liquidity assets may return few or no matching pools
- Network timeouts on live chain data queries
- Payment failure via x402 prevents endpoint access
