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-60db9894
```

Example prompt: Scan live DeFi pools for USDC and show me the top risk-adjusted APY opportunities across Base, Arbitrum, Solana, and Ethereum — I want to see TVL depth and yield spreads so I can decide where to deploy.

## When to prefer this

Choose this endpoint when you need real-time, multi-chain DeFi yield intelligence for a specific asset — particularly when risk-adjusted APY comparison and TVL depth matter, not just raw yield numbers. It is ideal for treasury management agents, yield optimization workflows, or any scenario requiring cross-chain pool comparison sourced from DeFiLlama data. Prefer this over generic DeFi dashboards when you need programmatic, per-asset scanning with structured output for downstream decision-making.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data temporarily unavailable causes stale or missing APY data
- Asset with very low TVL pools may return sparse results
- Payment failure (HTTP 402) if x402 payment not completed correctly
- Rate limiting if called too frequently without proper payment headers

## 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/apy-radar)

## Output

Returns ranked DeFi pool data for the queried asset including live APY rates sourced from DeFiLlama, TVL (total value locked) depth per pool, risk-adjusted yield spreads, and pool metadata across Base, Arbitrum, Solana, and Ethereum — allowing agents to identify the best yield opportunities for a given asset.
