## 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-d60589d7 -d '<json body>'
```

Example prompt: Scan live DeFiLlama pools for USDC and show me the top risk-adjusted yields across Base, Arbitrum, Solana, and Ethereum right now — I want to see APY, TVL depth, and any yield spread arbitrage opportunities.

## When to prefer this

Choose this endpoint when an agent needs live, cross-chain DeFi yield comparisons for a specific asset with risk-adjusted ranking and TVL context. Prefer over generic crypto price APIs when the goal is yield optimization, liquidity pool selection, or stablecoin arbitrage scouting. Best suited for DeFi treasury management, yield farming automation, or investment decision support.

## Known failure modes

- Missing or empty 'asset' field returns validation error
- Unsupported or misspelled asset symbol may return empty pool results
- DeFiLlama upstream data unavailability could result in stale or incomplete yield data
- Payment failure via x402 results in 402 response and no data returned
- Network timeouts if DeFiLlama API is slow to respond

## 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/stablecoin-yields)

## Output

Returns a ranked list of DeFi liquidity pools for the specified asset, including live APY rates sourced from DeFiLlama, TVL (total value locked) depth, risk-adjusted yield spreads, and cross-chain comparisons across Base, Arbitrum, Solana, and Ethereum. Enables agents to identify yield arbitrage opportunities and select optimal pools.
