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 cve-intel-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-3d17ee52
```

Example prompt: Scan the best risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me APYs, TVL depth, and which pool gives the top yield spread.

## When to prefer this

Choose this endpoint when you need a real-time, multi-chain comparison of DeFi yield opportunities for a specific asset, particularly for stablecoins or major crypto assets like ETH, SOL, or WBTC. It is ideal for yield optimization agents, DeFi treasury management, or arbitrage scanning workflows that require aggregated APY and TVL data from DeFiLlama across Base, Arbitrum, Solana, and Ethereum in a single call.

## Known failure modes

- Unknown or unsupported asset symbol returns an error or empty result set
- DeFiLlama data latency may cause stale APY values if upstream is lagging
- Very low-liquidity assets may return few or no pools
- Payment not processed (402 response) if x402 micropayment fails
- Malformed asset parameter (e.g. empty string) 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://cve-intel.agentdiet.dev/v1/defi-apy)

## Output

Returns a structured response containing top-ranked DeFi liquidity pools for the requested asset, including live APY rates sourced from DeFiLlama, TVL (total value locked) depth per pool, risk-adjusted yield spreads, and pool/chain metadata across Base, Arbitrum, Solana, and Ethereum.
