Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 mesh-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-arbitrage-5c0dcce8
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC across Base, Arbitrum, Solana, and Ethereum — show me the best APYs and TVL depth so I can figure out where to deploy capital.

## When to prefer this

Use this endpoint when you need live, cross-chain DeFi yield data for a specific asset symbol (USDC, ETH, SOL, WBTC, etc.) with TVL and risk-adjusted spread context — particularly for yield arbitrage decisions across Base, Arbitrum, Solana, and Ethereum. Prefer this over generic crypto price APIs when yield farming or liquidity pool optimization is the goal, and over static data sources when real-time APY accuracy matters.

## Known failure modes

- Missing or invalid asset symbol returns a 400/validation error
- Unknown or unsupported asset symbol may return empty pool results
- DeFiLlama data latency may cause slightly stale APY values during off-peak indexing
- Payment failure via x402 results in 402 response blocking data delivery
- Network/upstream DeFiLlama outage may cause 500 or empty response

## 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://mesh.agentdiet.dev/v1/yield-scanner)

## Output

Returns a structured list of DeFi pools for the queried asset, including live APY rates sourced from DeFiLlama, TVL depth, risk-adjusted yield spreads, and chain/protocol attribution across Base, Arbitrum, Solana, and Ethereum — enabling direct comparison and arbitrage decision-making.
