## 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 ethereum-defi-overview-tvl-protocols-stablecoins-dex-volume-fees-5fe01967 -d '<json body>'
```

Example prompt: Give me a full DeFi overview for Ethereum — TVL trend, the top protocols by TVL, stablecoin supply, DEX volume, and fee revenue right now.

## When to prefer this

Use this endpoint when you need a broad, multi-metric DeFi overview for Ethereum in a single call — covering TVL, protocols, stablecoins, DEX volume, and fees simultaneously. Prefer this over building separate calls to DeFiLlama or other sources when you need a consolidated snapshot for reporting, monitoring, or research purposes. Best suited for agents that need chain-level DeFi intelligence rather than deep dives into a single protocol.

## Known failure modes

- Upstream DeFi data source unavailable — returns an error or stale data
- Payment not processed correctly via x402 — returns 402 Payment Required
- Empty or malformed response if the Ethereum chain data feed is temporarily down
- Rate limiting if too many calls are made in rapid succession
