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 shopify-spy-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-1d44508e -d '<json body>'
```

Example prompt: Scan all the top DeFi pools for USDC right now and tell me which ones have the best risk-adjusted APY across Base, Arbitrum, Solana, and Ethereum — include TVL depth so I know which pools are safe enough to actually use.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset with risk-adjusted metrics already computed — rather than querying DeFiLlama directly or using a generic web search. It is especially useful when comparing multiple chains simultaneously (Base, Arbitrum, Solana, Ethereum) and when TVL-based risk filtering matters for the decision.

## Known failure modes

- Unknown or unsupported asset symbol returns an error or empty result set
- DeFiLlama data temporarily unavailable causes stale or missing APY data
- Pools with very low TVL may be excluded or flagged as high-risk
- Network timeout if upstream DeFiLlama API is slow
- Invalid asset string (empty or whitespace) rejected by schema validation

## 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://shopify-spy.agentdiet.dev/v1/morpho-vault-apy)

## Output

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