## 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-b949e745
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now — scan across Base, Arbitrum, Solana, and Ethereum and show me APYs and TVL depth so I can spot the best arbitrage opportunity.

## When to prefer this

Choose this endpoint when an agent needs real-time, multi-chain DeFi yield data for a specific asset and wants risk-adjusted comparisons rather than raw APY alone. It is ideal for yield optimization workflows, DeFi portfolio management agents, or arbitrage scouts that need TVL depth alongside APY. Prefer this over generic DeFi dashboards when you need programmatic, per-asset structured data across Base, Arbitrum, Solana, and Ethereum simultaneously.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data unavailability causes stale or missing APY data
- Payment failure (HTTP 402) if x402 micropayment is not processed
- Rate limiting if called too frequently without valid payment
- Malformed asset symbol (e.g. typo) may return no matching pools

## 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/stablecoin-yields)

## Output

Returns a structured object containing ranked DeFi liquidity pool opportunities for the queried asset, including live APY rates sourced from DeFiLlama, TVL depth metrics, risk-adjusted yield spreads, and chain identifiers (Base, Arbitrum, Solana, Ethereum), enabling agents to identify the best yield arbitrage opportunities.
