## 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 tokenguard-crypto-category-market-data-b7ea1d5c -d '<json body>'
```

Example prompt: What crypto market categories exist right now and which ones have the biggest market cap and 24-hour volume — like smart contract platforms, DeFi, layer 2s?

## When to prefer this

Use this endpoint when you need a high-level overview of crypto market sectors and their aggregate performance metrics, rather than data on individual tokens. Ideal for portfolio sector analysis, market trend dashboards, or determining which crypto verticals are gaining or losing momentum. Prefer over individual token endpoints when the user's question is sector- or category-level.
