## 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 x402-audit-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-61a84bbe
```

Example prompt: Scan the best risk-adjusted DeFi yield pools for USDC across Base, Arbitrum, Solana, and Ethereum — show me APYs, TVL depth, and any notable yield spread opportunities.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield comparisons for a specific asset (USDC, ETH, SOL, WBTC, etc.) sourced from DeFiLlama, especially when risk-adjusted APY and TVL depth across Base, Arbitrum, Solana, and Ethereum are needed in a single call. Prefer this over manual DeFiLlama browsing or single-protocol yield queries when you need a ranked, multi-chain view for yield arbitrage or treasury allocation decisions.

## Known failure modes

- Missing or empty 'asset' parameter returns a validation error
- Unknown or unsupported asset symbol may return empty results or an error
- DeFiLlama API downtime may cause stale or unavailable yield data
- Payment failure via x402 protocol results in HTTP 402 and no data returned
- Rate limiting or quota exhaustion may return a 429 response

## How this service works

Scans live DeFiLlama APYs, TVL depth, and risk-adjusted yield spreads across Base, Arbitrum, Solana, and Ethereum pools. (Live x402 v2, IETF MPP & MCP endpoint at https://x402-audit.agentdiet.dev/v1/aave-v3-yields)

## Output

Returns a ranked list of DeFi liquidity pools for the queried asset, including live APY rates sourced from DeFiLlama, TVL depth per pool, chain identifiers (Base, Arbitrum, Solana, Ethereum), and risk-adjusted yield spread comparisons to help identify the best yield opportunities.
