## 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 email-verify-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-6a438f93
```

Example prompt: Scan live DeFi pools across Base, Arbitrum, Solana, and Ethereum and show me the top risk-adjusted yield opportunities for USDC right now, including APYs and TVL depth.

## When to prefer this

Choose this endpoint when an agent needs live, cross-chain DeFi yield comparisons for a specific asset, especially when risk-adjusted APY and TVL depth matter more than just raw headline APY. It is best suited for yield optimization decisions across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over manually querying DeFiLlama or chain-specific protocols when you need a consolidated, ranked view in a single call.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- DeFiLlama data temporarily unavailable causes stale or empty results
- Unknown asset ticker not tracked by DeFiLlama returns no pools
- Payment not processed (HTTP 402) blocks the response
- Rate limiting or upstream API timeout returns an error

## 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://email-verify.agentdiet.dev/v1/morpho-vault-apy)

## Output

Returns a structured object containing live APY rates, TVL depth figures, and risk-adjusted yield spreads for the queried asset across multiple chains (Base, Arbitrum, Solana, Ethereum), ranking pools so the agent can identify the best yield opportunities.
