## 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 agentdiet-dev-defi-stablecoin-liquidity-pool-yield-arbitrage-scanner-5bec1a8f
```

Example prompt: What are the best risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me the top APYs and TVL depth so I can find the best opportunity?

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield comparison for a specific asset — particularly when risk-adjusted APY and TVL depth matter for decision-making. Prefer this over manual protocol browsing or single-chain yield tools when you need a unified view across Base, Arbitrum, Solana, and Ethereum simultaneously. Best suited for yield optimization, treasury deployment decisions, and DeFi arbitrage scouting.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data temporarily unavailable causing stale or missing APY data
- No pools found for the requested asset on any supported chain
- Rate limiting or payment failure (HTTP 402) if micropayment not completed
- Malformed asset symbol input returns validation error
