## 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-96d51b0d
```

Example prompt: Can you scan the best risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — I want to see APYs and TVL depth so I can decide where to deploy capital?

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data for a specific asset symbol and want risk-adjusted APY comparisons across Base, Arbitrum, Solana, and Ethereum in a single call. Prefer it over manual DeFiLlama browsing or single-chain yield checkers when cross-chain arbitrage scanning is needed.

## Known failure modes

- Missing or empty 'asset' parameter returns a validation error
- Unsupported or misspelled asset symbol may return no results or an error
- DeFiLlama data unavailability may result in stale or empty yield data
- Rate limiting or payment failure (HTTP 402) if USDC micropayment not fulfilled
- Network timeouts if upstream DeFiLlama API is slow

## 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/pendle-pt-yields)

## Output

Returns a ranked list of DeFi liquidity pools for the queried asset, including live APYs sourced from DeFiLlama, TVL depth per pool, risk-adjusted yield spreads, and chain attribution (Base, Arbitrum, Solana, Ethereum) to help identify the best yield opportunities.
