## 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 x402-audit-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-fbc380de
```

Example prompt: What are the top risk-adjusted USDC yield pools right now across Base, Arbitrum, Solana, and Ethereum — ranked by APY and TVL depth?

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset aggregated from DeFiLlama — especially when comparing risk-adjusted APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum in a single call. Prefer this over manual DeFiLlama browsing or chain-specific tools when your agent needs a ranked, arbitrage-ready yield comparison.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Unknown or unsupported asset symbol may return empty results
- DeFiLlama data latency may cause slightly stale APY readings
- Payment failure via x402 blocks the request
- Rate limiting if called too frequently
