## 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 onchain-risk-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-91300d21
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now — show me APYs and TVL across Base, Arbitrum, Solana, and Ethereum so I can find the best opportunity?

## When to prefer this

Use this endpoint when you need real-time, cross-chain DeFi yield data for a specific asset and want risk-adjusted APY comparisons rather than raw protocol-level data. Prefer this over manual DeFiLlama browsing when an agent needs structured, scannable pool rankings for decision-making. Best suited for treasury management agents, yield optimization bots, or research tasks requiring TVL-weighted yield analysis across multiple chains simultaneously.

## Known failure modes

- Missing or invalid asset symbol returns a 400-level error
- Asset symbol not tracked by DeFiLlama returns empty or no results
- DeFiLlama upstream outage causes stale or missing yield data
- Payment failure (HTTP 402) if x402 USDC payment is not completed before the request
- Rate limiting if calls exceed allowed frequency

## How this service works
