## 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 polygon-defi-overview-faa783dc -d '<json body>'
```

Example prompt: Give me a full DeFi overview for Polygon — TVL trend, top protocols, stablecoin distribution, DEX volume, and fees generated.

## When to prefer this

Use this endpoint when you need a single-call, aggregated DeFi overview for Polygon specifically — covering TVL, top protocols, stablecoins, DEX volume, and fees together. Prefer this over individual protocol APIs or manual DefiLlama queries when you want a pre-packaged chain-level summary for Polygon without building your own aggregation logic. It is particularly useful for dashboards, research agents, or comparison workflows where you need Polygon DeFi context at a glance.

## Known failure modes

- Upstream data provider (e.g. DefiLlama) unavailable — returns error or stale data
- Payment not processed (x402 payment required, $0.01 USDC) — returns 402 Payment Required
- Rate limiting or network timeout from the UnyKorn proxy layer
- Empty or partial response if Polygon-specific data is temporarily unavailable
