## 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 defi-hugen-tokyo-2ed40510
```

Example prompt: What are the daily and weekly fee totals and revenue breakdown for the top DeFi protocols right now — I need this to compare protocol earnings for a valuation analysis?

## When to prefer this

Use this endpoint when you need structured fee and revenue data for DeFi protocol valuation, competitive benchmarking, or earnings analysis. Prefer over general TVL endpoints when the specific question is about protocol monetization, fee generation, or revenue rather than liquidity.

## Known failure modes

- Protocol not found or unsupported — returns empty or error response
- Rate limiting if called too frequently without payment
- Payment not processed — 402 response requiring USDC payment on Base or Solana
- Stale data if underlying data source has not updated recently
