Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-fcc7d2fd
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC across Base, Arbitrum, Solana, and Ethereum and show me which pools have the best APY and TVL depth right now.

## When to prefer this

Use this endpoint when an agent needs to compare live DeFi yield opportunities for a specific asset across multiple chains simultaneously, particularly when TVL depth and risk-adjusted spread matter alongside raw APY. Prefer this over manually querying individual protocol APIs when cross-chain arbitrage scanning or stablecoin yield optimization is the goal.

## Known failure modes

- Invalid or unrecognized asset symbol returns an error or empty result
- DeFiLlama data unavailability may cause stale or missing pool data
- No pools found for obscure or illiquid assets
- Payment failure (HTTP 402) if x402 USDC micropayment is not properly handled
- Rate limiting if called too frequently

## 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/lending-rates)

## Output

Returns a structured breakdown of top DeFi pools for the requested asset, including live APY rates sourced from DeFiLlama, TVL depth per pool, risk-adjusted yield spreads, and rankings across Base, Arbitrum, Solana, and Ethereum chains.
