## 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 rootstock-defi-overview-77ac03cf -d '<json body>'
```

Example prompt: Give me a full DeFi overview for Rootstock — I want the current TVL trend, which protocols are leading, stablecoin breakdown, DEX volume, and fee data.

## When to prefer this

Use this endpoint when you need a quick, aggregated DeFi overview specific to the Rootstock (RSK) Bitcoin sidechain — covering TVL, protocols, stablecoins, DEX volume, and fees in a single call. Prefer this over general blockchain explorers when you want DeFi-specific metrics rather than raw transaction data, and when Rootstock is specifically your chain of interest rather than Ethereum, Solana, or other chains.

## Known failure modes

- Upstream DeFi data provider unavailable — may return partial or stale data
- Rootstock chain data temporarily unavailable — 5xx error
- Payment not fulfilled — 402 response requiring x402 USDC payment
- Empty or null fields if Rootstock has very low activity in a given period
