## 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 aptos-defi-overview-4546550e -d '<json body>'
```

Example prompt: Can you pull up the current DeFi overview for Aptos — I want to see the TVL trend, which protocols are on top, stablecoin volumes, DEX trading volume, and fee data?

## When to prefer this

Use this endpoint when you need a holistic, multi-metric DeFi snapshot of the Aptos chain in a single call rather than querying TVL, DEX volume, fees, and stablecoins separately. Prefer this over generic DeFi aggregator APIs when you specifically need Aptos data with a pay-per-call model and no API key management.

## Known failure modes

- Upstream data source unavailable — returns 5xx or empty payload
- Payment not processed — returns 402 Payment Required if x402 payment header is missing or insufficient
- Stale data if upstream DeFi data provider has not updated recently
- Empty or partial response if Aptos chain data is temporarily unavailable
