## 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 defi-yield-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-b3162bd6
```

Example prompt: Scan live DeFi pools across Base, Arbitrum, Solana, and Ethereum and show me the top risk-adjusted yields for USDC, including APY and TVL for each pool.

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data for a specific asset and want risk-adjusted rankings rather than raw APY alone. It is particularly valuable when comparing yield opportunities across Base, Arbitrum, Solana, and Ethereum simultaneously, or when TVL depth matters for assessing liquidity risk. Prefer this over generic crypto price APIs when the goal is yield optimization or liquidity pool selection.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data temporarily unavailable causes stale or missing APY data
- Very new or low-liquidity assets may have no matching pools
- Payment not processed (x402) results in 402 response blocking data access
- Rate limiting or network errors return 5xx responses

## 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://defi-yield.agentdiet.dev/v1)

## Output

Returns a ranked list of DeFi liquidity pools for the requested asset, including live APY rates sourced from DeFiLlama, TVL (total value locked) depth per pool, risk-adjusted yield spreads, and chain attribution across Base, Arbitrum, Solana, and Ethereum.
