## 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-96d7e22c -d '<json body>'
```

Example prompt: Scan DeFi for the best risk-adjusted yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — I want to see top APYs with TVL depth so I know which pools are actually liquid.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset and want risk-adjusted APY comparisons with TVL depth in a single call. It aggregates DeFiLlama data across Base, Arbitrum, Solana, and Ethereum, making it ideal for yield optimization, liquidity pool selection, and DeFi arbitrage research. Prefer it over manually querying DeFiLlama directly when you want pre-filtered, agent-ready output.

## Known failure modes

- Invalid or unrecognized asset symbol returns empty or error response
- DeFiLlama API unavailability may cause stale or missing data
- Very small or niche assets may have no indexed pools
- Network timeout if upstream DeFiLlama data fetch is slow
- Malformed request body (missing required 'asset' field) returns 400-level error

## 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/lp-apy-scanner)

## Output

Returns a structured list of top liquidity pools for the requested asset, including live APY rates sourced from DeFiLlama, TVL depth per pool, protocol names, supported chains (Base, Arbitrum, Solana, Ethereum), and risk-adjusted yield spreads to help identify the most attractive yield opportunities.
