## 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 joe-market-data-protocol-revenue-leaders-38f92974
```

Example prompt: Can you pull up the top DeFi protocols by fees earned in the last 24 hours, including their take rates, from DefiLlama?

## When to prefer this

Use this endpoint when you need a real-time ranked leaderboard of DeFi protocols by 24-hour fee revenue, especially when comparing protocol monetization or identifying the most economically active protocols. Prefer this over generic token price endpoints when the focus is protocol-level revenue and take rates rather than token valuations.

## Known failure modes

- DefiLlama upstream unavailable — may return empty data or error status
- Payment not processed — x402 payment required before data is returned
- Stale data if DefiLlama has not refreshed its fee metrics recently
- Malformed response if upstream schema changes
