# DeFi Stablecoin & Liquidity Pool Yield Arbitrage Scanner

> DeFi Stablecoin & Liquidity Pool Yield Arbitrage Scanner is a paid API for AI agents from mcp-compiler.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Scans live DeFiLlama APYs, TVL depth, and risk-adjusted yield spreads for a given asset across Base, Arbitrum, Solana, and Ethereum pools.

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 mcp-compiler-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-d44cc177
```

Example prompt: Scan all the top DeFi pools for USDC right now and show me the best risk-adjusted APYs across Ethereum, Base, Arbitrum, and Solana — I want to see TVL depth and yield spreads so I can find the best place to deploy capital.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset and want risk-adjusted comparisons rather than raw APY alone. It is especially useful for agents performing yield optimization, capital allocation decisions, or arbitrage scouting across multiple EVM and Solana chains simultaneously, using DeFiLlama as a trusted data source.

## Known failure modes

- Missing or invalid 'asset' parameter returns a validation error
- Unknown asset symbols (e.g. obscure tokens) may return empty results or no matching pools
- DeFiLlama API downtime or rate-limiting may cause stale or failed data
- Pools with very low TVL may not appear in results due to depth filtering
- Payment failure (x402) blocks access before any data is returned

## 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://mcp-compiler.agentdiet.dev/v1/lending-rates)

## Output

Returns a structured object containing ranked DeFi pool data for the requested asset, including live APY rates sourced from DeFiLlama, TVL (total value locked) depth per pool, risk-adjusted yield spreads, and pool/protocol metadata across Base, Arbitrum, Solana, and Ethereum.
