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 email-verify-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-5597c00d
```

Example prompt: Scan all DeFi liquidity pools for USDC and show me the top risk-adjusted yields ranked by APY and TVL depth across Base, Arbitrum, Solana, and Ethereum right now.

## When to prefer this

Choose this endpoint when you need a real-time, cross-chain comparison of DeFi yield opportunities for a specific asset, particularly when risk-adjusted APY and TVL depth matter. Prefer this over manually querying DeFiLlama or checking individual protocol dashboards when an agent needs structured, rankable yield data programmatically for USDC, ETH, SOL, WBTC, or other major assets.

## Known failure modes

- Missing or invalid asset symbol returns a 400 validation error
- Unknown or unsupported asset symbols may return empty pool results
- DeFiLlama data unavailability may cause stale or missing APY data
- Payment not completed (HTTP 402) if x402 micropayment is not handled
- Rate limiting or timeout if upstream DeFiLlama API is slow or down

## 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/aave-v3-yields)

## Output

Returns a ranked list of DeFi liquidity pools for the requested asset, including APY rates sourced from DeFiLlama, TVL depth figures, risk-adjusted yield spreads, and the associated protocol and chain for each pool, enabling direct yield comparison across Base, Arbitrum, Solana, and Ethereum.
