## 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 protocol-fees-revenue-rankings-7d65c917
```

Example prompt: Show me the top 20 crypto protocols ranked by revenue over the last 7 days on Ethereum — I want to use this for fundamental analysis.

## When to prefer this

Use this endpoint when you need protocol-level fee and revenue rankings for fundamental analysis or valuation — especially when comparing multiple protocols across time horizons (24h/7d/30d). Prefer this over price-based endpoints when evaluating real economic activity. Ideal for screening DeFi protocols, chains, and stablecoin issuers by actual cash flows rather than market cap.

## Known failure modes

- Invalid chain name returns empty results or error
- Limit outside 1-100 range may be rejected
- Invalid metric value (not 'fees' or 'revenue') may return error
- Service may be unavailable if the Render.com deployment is cold-started or down
- No historical data beyond 30d window

## How this service works

Crypto protocols ranked by fees paid by users or revenue kept (Tether, Circle, Uniswap, Hyperliquid, chains...) over 24h, 7d and 30d, for all chains or one chain. Use for fundamental analysis and protocol valuation.

## Output

A ranked list of crypto protocols (e.g. Tether, Circle, Uniswap, Hyperliquid, major L1/L2 chains) with their fees paid by users and/or revenue kept, broken down by 24h, 7d, and 30d time windows, optionally filtered to a specific chain.
