## 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 domain-osint-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-b6ad2ebd
```

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

Choose this endpoint when you need a real-time, cross-chain yield comparison for a specific asset across major DeFi protocols (Base, Arbitrum, Solana, Ethereum). It is best suited for yield arbitrage scanning, portfolio allocation decisions, and risk-adjusted yield ranking using live DeFiLlama data. Prefer this over generic DeFi aggregators when you need TVL depth alongside APY to assess liquidity risk.

## Known failure modes

- Missing or invalid asset symbol returns a 400 validation error
- DeFiLlama data unavailable or stale may result in incomplete pool coverage
- Asset not listed on DeFiLlama returns empty results or 404
- Payment not completed (HTTP 402) blocks access to results
- Network latency on live data fetches may cause timeouts

## 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://domain-osint.agentdiet.dev/v1/yield-aggregator)

## Output

Returns a structured list of top DeFi liquidity pools for the requested asset, including APY rates sourced from DeFiLlama, TVL depth, risk-adjusted yield spreads, and pool metadata broken down by chain (Base, Arbitrum, Solana, Ethereum), enabling yield comparison and arbitrage identification.
