Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability pulsechain-defi-overview-043191b1 -d '<json body>'
```

## When to prefer this

Use this endpoint when you need a holistic, multi-metric DeFi snapshot of the PulseChain network in a single call. Prefer it over chain-specific block explorers or general DeFi dashboards when you need TVL trend, stablecoin, DEX volume, and fee data together for PulseChain specifically.
