## 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 cve-intel-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-a6d62cb9
```

Example prompt: What are the best risk-adjusted DeFi yield pools for USDC right now — scan across Base, Arbitrum, Solana, and Ethereum and show me the top APYs with TVL depth?

## When to prefer this

Use this endpoint when an agent needs live, cross-chain DeFi yield data for a specific asset to identify the best liquidity pool opportunities by APY and risk profile. Prefer over static yield tables or single-chain tools when the user wants a multi-chain scan (Base, Arbitrum, Solana, Ethereum) with TVL-weighted risk adjustment. Best suited for treasury optimization, yield arbitrage discovery, or pre-deployment pool scouting.

## Known failure modes

- Missing or invalid asset symbol returns an error — only recognized token symbols (USDC, ETH, SOL, WBTC, etc.) are supported
- DeFiLlama data unavailable or stale may result in incomplete or cached pool data
- Pools with very low TVL may be excluded from risk-adjusted rankings
- Payment failure via x402 returns HTTP 402 before scan is executed
- Unknown or illiquid assets may return empty pool results

## 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://cve-intel.agentdiet.dev/v1/yield-aggregator)

## Output

Returns a ranked list of DeFi liquidity pools for the requested asset, including live APY rates sourced from DeFiLlama, TVL depth per pool, risk-adjusted yield spreads, and chain attribution (Base, Arbitrum, Solana, Ethereum), enabling direct comparison of yield opportunities.
