## 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-5ba3bce8 -d '<json body>'
```

Example prompt: Scan across Base, Arbitrum, Solana, and Ethereum and find me the top risk-adjusted DeFi yield pools for USDC right now — I want to see APYs, TVL depth, and which protocol has the best spread.

## When to prefer this

Use this endpoint when you need live, cross-chain DeFi yield data for a specific asset and want risk-adjusted comparisons rather than raw APY alone. Prefer this over manually querying DeFiLlama when you need structured, agent-consumable output across multiple chains simultaneously. Best suited for yield optimization workflows, treasury management agents, or DeFi arbitrage bots that need fast, ranked pool data.

## Known failure modes

- Invalid or unsupported asset symbol returns an error or empty results
- DeFiLlama data unavailability may cause stale or missing APY values
- Very low-liquidity assets may return few or no pools
- Network timeouts if upstream DeFiLlama API is slow
- Payment failure (402) if USDC micropayment is not attached correctly

## How this service works

## Output
