## 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 hn-pulse-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-arbitrage-1b97d75c -d '<json body>'
```

Example prompt: What are the best risk-adjusted DeFi yield pools for USDC 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 and want risk-adjusted pool rankings rather than raw APY lists. It is ideal for agents managing treasury allocations, DeFi yield optimization strategies, or arbitrage detection across Base, Arbitrum, Solana, and Ethereum. Prefer this over generic DeFiLlama API calls when you need pre-ranked, agent-ready output with TVL depth context included.

## Known failure modes

- Unknown or unsupported asset symbol returns empty or error response
- DeFiLlama data unavailability causes stale or missing APY data
- Pools with very low TVL may be excluded from risk-adjusted ranking
- Payment failure via x402 returns HTTP 402 before scan executes
- Malformed asset input (empty string) rejected by schema validation
