## 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 defi-yield-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-2e7ab05f
```

Example prompt: Scan live DeFi pools for USDC and show me the top risk-adjusted APYs across Base, Arbitrum, Solana, and Ethereum right now — I want to know where to get the best yield with the most TVL backing.

## When to prefer this

Choose this endpoint when you need real-time, multi-chain DeFi yield data for a specific asset and want risk-adjusted comparisons across major EVM and Solana ecosystems — especially when Morpho vault data is relevant. Prefer it over generic DeFi dashboards when an agent needs structured, machine-readable APY and TVL data it can act on programmatically.

## Known failure modes

- Unsupported or misspelled asset symbol returns empty results or error
- DeFiLlama API downtime causes stale or missing data
- Low-TVL assets may have sparse pool coverage
- Payment failure (HTTP 402) if x402 microtransaction is not properly handled
- Rate limiting if called too frequently without payment
