## 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-97581455
```

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

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data sourced from DeFiLlama for a specific asset, especially when you want risk-adjusted APY comparisons and TVL depth across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over manual DeFiLlama browsing or single-chain yield aggregators when an agent needs programmatic, structured yield rankings for stablecoins or major crypto assets.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Unknown or very low-liquidity token symbols may return empty results
- DeFiLlama API downtime may result in stale or unavailable data
- Payment failure via x402 prevents endpoint access
- Asset symbols with multiple representations (e.g. WETH vs ETH) may return incomplete coverage

## 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/yield-aggregator)

## Output

Returns a list of DeFi pools for the requested asset, including APY values sourced from DeFiLlama, TVL depth, risk-adjusted yield spreads, chain names (Base, Arbitrum, Solana, Ethereum), and pool identifiers to help rank and compare yield opportunities.
