## 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 defi-yield-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-f32a88e1 -d '<json body>'
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — ranked by APY and TVL depth?

## When to prefer this

Use this endpoint when you need a real-time, multi-chain comparison of DeFi yield opportunities for a specific asset, especially when TVL depth and risk-adjusted spreads matter for deployment decisions. Prefer this over single-protocol dashboards or manual DeFiLlama browsing when you need aggregated, ranked results ready for agent consumption.

## Known failure modes

- Invalid or unrecognized asset symbol returns an error or empty result set
- DeFiLlama data unavailability may cause stale or missing APY data
- Low-TVL or newly launched pools may lack sufficient depth data
- Rate limiting or payment failure (HTTP 402) if per-call payment is not processed

## 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://defi-yield.agentdiet.dev/v1/yield-aggregator)

## Output

Returns a ranked list of DeFi liquidity pools for the requested asset, including live APYs sourced from DeFiLlama, TVL depth per pool, chain labels (Base, Arbitrum, Solana, Ethereum), and risk-adjusted yield spread metrics to help identify the most attractive yield opportunities.
