## 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-b5aca444 -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 and TVL depth right now.

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield intelligence for a specific asset rather than static or aggregated data. It is ideal for agents optimizing treasury deployment, yield farming strategies, or arbitrage detection across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer it over manual DeFiLlama browsing when you need programmatic, risk-adjusted ranking rather than raw APY lists.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data unavailability causes stale or missing APY data
- Very new or illiquid tokens may have no matching pools
- Payment failure (HTTP 402) if USDC balance is insufficient
- Rate limiting or timeout if DeFiLlama upstream is slow

## How this service works
