## 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 stellar-defi-overview-2dacac96 -d '<json body>'
```

Example prompt: Give me the latest DeFi overview for Stellar — including TVL trend, top protocols, stablecoin breakdown, DEX volume, and fee stats.

## When to prefer this

Use this endpoint when you need a broad, multi-metric DeFi overview specifically for the Stellar blockchain — TVL, protocols, stablecoins, DEX volume, and fees in one call. Prefer it over chain-agnostic DeFi APIs when Stellar-specific aggregated data is needed without assembling metrics from multiple sources.

## Known failure modes

- Upstream DeFi data provider outage resulting in stale or missing data
- Empty response if Stellar DeFi data is temporarily unavailable
- Payment failure if the $0.01 USDC x402 payment is not included or fails
- Timeout if the data aggregation takes longer than expected
