## 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 mcp-compiler-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-7af39191
```

Example prompt: Scan across Base, Arbitrum, Solana, and Ethereum and find me the top risk-adjusted DeFi yield pools for USDC right now, including APY and TVL depth.

## 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 rather than raw rates. It is particularly useful for agents making capital allocation decisions, identifying yield arbitrage opportunities, or monitoring DeFi pool attractiveness across Base, Arbitrum, Solana, and Ethereum in a single call. Prefer it over manual DeFiLlama scraping when you need token-efficient, pre-ranked output.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Unknown asset symbol with no matching pools returns empty or error response
- DeFiLlama upstream data unavailability may cause stale or failed responses
- Rate limiting or payment failure (402) if USDC micropayment is not processed
- Chains with low liquidity for the requested asset may return sparse results

## How this service works
