## 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 serp-extract-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-3afbe864
```

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 the best APYs and TVL depth?

## When to prefer this

Prefer this endpoint when you need live, cross-chain DeFi yield comparisons for a specific asset, especially when risk-adjusted APY and TVL depth are important signals. It is ideal for yield arbitrage discovery, DeFi portfolio optimization, and stablecoin yield routing decisions. It is not suited for CEX rates, traditional finance rates, or non-DeFi savings products.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- DeFiLlama data feed delay or downtime may result in stale or empty results
- Unsupported or low-liquidity assets may return few or no matching pools
- Network timeout if upstream DeFiLlama API is slow
- Payment failure via x402 may block access to results

## 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://serp-extract.agentdiet.dev/v1/lending-rates)

## Output

Returns a structured object containing live APY rates, TVL depth figures, and risk-adjusted yield spreads for the queried asset across supported chains (Base, Arbitrum, Solana, Ethereum), ranked by yield attractiveness and risk profile.
