## 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 hn-pulse-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-arbitrage-e0d240cd
```

Example prompt: What are the best risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me APYs and TVL depth so I can see where to put my stablecoins?

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data for a specific asset and want risk-adjusted APY comparisons rather than raw APY alone. It is ideal for DeFi yield optimization, treasury management, or arbitrage scouting across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over general-purpose DEX price feeds when TVL depth and yield spread analysis across multiple chains is the primary goal.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Asset symbol not tracked by DeFiLlama returns empty or no results
- DeFiLlama API downtime may cause stale or unavailable data
- Very low-liquidity tokens may return minimal pool options
- Payment failure (HTTP 402) if x402 micropayment is not processed correctly

## 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://hn-pulse.agentdiet.dev/v1/yield-scanner)

## Output

Returns a structured list of top DeFi liquidity pools for the queried asset, including live APY rates sourced from DeFiLlama, TVL depth per pool, risk-adjusted yield spreads, and chain-level breakdowns across Base, Arbitrum, Solana, and Ethereum — enabling direct comparison and arbitrage opportunity identification.
