## 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-e8b17d2f
```

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

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield comparisons for a specific asset and want risk-adjusted scoring alongside raw APY — particularly useful for stablecoin treasury management, yield arbitrage scouting, or DeFi capital allocation decisions. Prefer it over manual DeFiLlama browsing or single-chain tools when you need a cross-chain ranked view in a single API call.

## Known failure modes

- Missing or invalid asset symbol returns a 400-level error
- Unknown or unsupported asset symbol yields no matching pools
- DeFiLlama data freshness lag may cause stale APY readings during market volatility
- Payment not fulfilled (HTTP 402) if x402 micropayment is not completed before call
- Pools with very low TVL may not appear in results or may show unreliable APY data

## 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/lending-rates)

## Output

Returns a ranked list of DeFi lending and liquidity pool opportunities for the requested asset, including live APY figures sourced from DeFiLlama, TVL depth per pool, chain identifiers (Base, Arbitrum, Solana, Ethereum), protocol names, and risk-adjusted yield spread scores to help identify the best deposit opportunity.
