## 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 github-audit-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-7fac60e2
```

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 aggregated from DeFiLlama with risk-adjusted scoring — particularly useful for agents making yield optimization decisions across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over raw DeFiLlama API access when you want pre-ranked, risk-weighted results without building your own scoring logic.

## Known failure modes

- Unknown or unsupported asset symbol returns empty or error response
- DeFiLlama data temporarily unavailable causing stale or missing APY data
- Rate limiting or payment failure (HTTP 402) if USDC micropayment not processed
- Malformed asset parameter (empty string) rejected per schema minLength:1
- Pools with very low TVL may be excluded from risk-adjusted rankings

## How this service works
