## 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 json-repair-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-be881bb4
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me the best APYs and TVL depth so I can decide where to deploy.

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield intelligence for a specific asset — particularly when comparing risk-adjusted APYs and TVL across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer it over manual DeFiLlama browsing or single-chain yield queries when you need a consolidated, agent-ready ranked output in one call.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Unknown or unsupported asset symbol yields empty or no matching pools
- DeFiLlama upstream unavailability may cause stale or failed data
- Payment not processed (HTTP 402) if x402 micropayment is not completed
- Rate limiting if too many calls are made in quick succession
