## 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 cardano-defi-overview-f278c5eb -d '<json body>'
```

Example prompt: Give me a full DeFi overview for Cardano — I want to see the TVL trend, top protocols by liquidity, stablecoin breakdown, DEX trading volume, and fee data.

## When to prefer this

Use this endpoint when you need a consolidated DeFi snapshot for Cardano specifically, covering TVL, protocols, stablecoins, DEX volume, and fees in a single call. Prefer it over general-purpose DeFi APIs when you need Cardano-native data from a pay-per-call micropayment model and don't want to manage API keys.

## Known failure modes

- Data source unavailable — DeFi aggregator backend may be temporarily unreachable
- Stale data returned if upstream indexing is delayed
- Empty or partial response if Cardano chain data provider is lagging
- Payment of $0.01 USDC required per call via x402 protocol; unpaid requests will be rejected
