## 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 clonecho-protocol-fees-leaderboard-b757dc6e -d '<json body>'
```

Example prompt: Show me which DeFi protocols are generating the most fees right now — I want the live 24-hour leaderboard ranked by real economic activity, not just hype.

## When to prefer this

Use this endpoint when you need a real-time, fee-based ranking of DeFi/crypto protocols as a proxy for genuine economic activity — ideal for filtering out hype and identifying protocols with actual usage. Prefer this over market-cap or TVL rankings when economic throughput matters.

## Known failure modes

- Upstream data source unavailable — may return 502 or empty dataset
- Stale data if live feed is temporarily delayed
- Payment required error (402) if USDC payment not attached
- Protocol list may be incomplete if some chains are not indexed
