## 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-b016c79b
```

Example prompt: Scan the best risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me APYs, TVL depth, and which protocols have the highest spreads.

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data for a specific asset and want risk-adjusted comparisons across real liquidity pools rather than static or aggregated summaries. It is especially useful for agents executing yield optimization strategies, portfolio rebalancing decisions, or DeFi arbitrage workflows where current APY and TVL depth matter. Prefer this over generic DeFi news or price feeds when the goal is actionable yield placement.

## Known failure modes

- Missing or empty asset symbol returns a validation error
- Unknown or unsupported asset symbol may return empty results or an error
- DeFiLlama API downtime may cause stale or missing yield data
- Highly illiquid assets with no indexed pools return empty result sets
- Payment failure (HTTP 402) if x402 micropayment is not properly handled

## 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/morpho-vault-apy)

## Output

Returns a ranked list of DeFi liquidity pools and vaults for the queried asset, including live APY rates pulled from DeFiLlama, TVL depth figures, risk-adjusted yield spreads, protocol names, and chain identifiers across Base, Arbitrum, Solana, and Ethereum.
