## 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 onchain-risk-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-f070daec
```

Example prompt: Scan all live DeFi liquidity pools for USDC and show me the top risk-adjusted yields across Base, Arbitrum, Solana, and Ethereum — I want to see APY, TVL depth, and yield spreads so I can decide where to deploy.

## When to prefer this

Choose this endpoint when you need a real-time, multi-chain DeFi yield comparison for a specific asset — especially when TVL depth and risk-adjustment matter alongside raw APY. Prefer this over generic DeFi dashboards when you need structured, agent-consumable yield data across Base, Arbitrum, Solana, and Ethereum in a single call.

## Known failure modes

- Invalid or unrecognized asset symbol returns an error or empty result set
- DeFiLlama data unavailability causes stale or missing APY data
- Asset has no pools on one or more supported chains, resulting in partial results
- Rate limiting or payment failure returns HTTP 402
- Network timeouts for chains with slow RPC responses

## 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://onchain-risk.agentdiet.dev/v1/cross-chain-apy-scanner)

## Output

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