## 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 base-defi-overview-tvl-trend-top-protocols-stablecoins-dex-volume-fees-d07d5601 -d '<json body>'
```

Example prompt: Can you pull up the current DeFi overview for Base — I want to see the TVL trend, which protocols are on top, stablecoin breakdown, DEX trading volume, and what fees are being generated?

## When to prefer this

Choose this endpoint when you need a broad, multi-metric DeFi overview of the Base blockchain in a single call rather than querying individual metrics separately. Ideal for dashboards, reports, or agent workflows that need TVL, protocol rankings, stablecoin data, DEX volume, and fees all at once without assembling from multiple sources.

## Known failure modes

- Upstream DeFi data provider outage may return stale or empty data
- Payment failure (402) if x402 payment is not properly attached
- Rate limiting if called too frequently without payment
- Partial data if one of the sub-metrics (e.g. stablecoins) is temporarily unavailable from source
