## 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-da3218df
```

Example prompt: Scan all the top DeFi liquidity pools across Ethereum, Base, Arbitrum, and Solana and tell me where I can earn the best risk-adjusted yield on USDC right now, including APY, TVL, and which protocol each pool is on.

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield comparison for a specific asset, especially when risk-adjusted APY and TVL depth matter — not just raw APY. Prefer it over manual DeFiLlama browsing when an agent needs structured, scannable yield data programmatically across Base, Arbitrum, Solana, and Ethereum in a single call.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or an error
- DeFiLlama data unavailable or stale due to upstream outage
- Asset symbol ambiguity (e.g. multiple tokens sharing same ticker) may return incorrect pools
- Payment failure via x402 results in 402 response with no data
- Rate limiting may occur under heavy usage
- Very new or low-liquidity tokens may return zero pool results

## How this service works

## Output

Returns a ranked list of DeFi liquidity pools for the queried asset, including protocol name, chain, current APY, TVL depth, and risk-adjusted yield spread, sourced live from DeFiLlama data across Base, Arbitrum, Solana, and Ethereum.
