## 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-9f78150e
```

Example prompt: What are the best risk-adjusted DeFi yield pools for USDC right now across Ethereum, Base, Arbitrum, and Solana — show me live APYs and TVL depth so I can pick the safest highest-yielding option?

## 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 particularly useful when comparing opportunities across Base, Arbitrum, Solana, and Ethereum simultaneously, sourcing data from DeFiLlama. Prefer this over manual DeFiLlama browsing when an agent needs programmatic, token-efficient yield intelligence for treasury management, yield arbitrage, or portfolio rebalancing decisions.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data temporarily unavailable causing stale or missing APY data
- Payment failure (HTTP 402) if x402 micropayment is not correctly handled
- Rate limiting if called too frequently without proper payment
- Pools with very low TVL may show misleadingly high APYs that are not practically accessible

## 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/pendle-pt-yields)

## Output

Returns a ranked list of DeFi pools for the requested asset, including live APY rates sourced from DeFiLlama, TVL depth figures, risk-adjusted yield spreads, and chain breakdown across Base, Arbitrum, Solana, and Ethereum — enabling direct comparison of yield opportunities.
