## 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 stablejack-defi-category-metrics-626a67ee -d '<json body>'
```

Example prompt: Pull the latest DeFi category metrics from StableJack — I want to see TVL, volume, and fees broken down by protocol category so I can spot which DeFi sectors are leading right now.

## When to prefer this

Use this endpoint when you need aggregated DeFi sector-level data rather than individual protocol or token data. It is ideal for macro DeFi research, capital allocation decisions, sector comparison, and market trend analysis. Prefer this over token-specific endpoints when the goal is to understand category-level dynamics such as which DeFi verticals are growing, leading in TVL, or generating the most fees.

## Known failure modes

- Invalid or missing body parameters return an error response with ok: false
- Unsupported category filter causes empty or error data
- Payment failure (x402) prevents access to the endpoint
- Network timeout if upstream data provider is slow
- Rate limiting if called too frequently without valid payment

## How this service works

Retrieve defi category metrics through StableJack's agent-ready research API.

## Output

Returns a structured JSON object containing aggregated metrics for DeFi protocol categories, likely including TVL, trading volume, fees generated, number of protocols, and growth rates — organized by category type (e.g. DEX, lending, liquid staking, yield, etc.).
