## 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 agent402-defi-fees-revenue-data-0848cc9f -d '<json body>'
```

Example prompt: Pull the top 10 DeFi protocols on Ethereum ranked by fees, filtered to just DEXs, and show me their 24-hour and 7-day fee totals.

## When to prefer this

Use this endpoint when you need structured, ranked DeFi fee or revenue data with filtering by chain, category, or protocol name — especially when you want multi-window time comparisons (24h/7d/30d/1y) in one call. Prefer it over raw DefiLlama API calls when you need a pay-per-call, no-signup interface with pre-normalized output. It's ideal for agent workflows that need to rank protocols, detect fee spikes, or compare chains without managing API keys.

## Known failure modes

- Invalid chain name returns empty or unfiltered results
- Limit exceeding 100 is clamped or returns an error
- Unknown category string produces zero results (case-insensitive exact match required)
- Stale cache may cause fetchedAt timestamp to lag real-time by minutes
- Payment failure (insufficient USDC) results in 402 response before any data is returned

## How this service works

Protocols ranked by fees paid by users or by revenue kept, with 24h, 7d, 30d, 1y and all-time totals, change, category and chains, and chain-level gas fees on request. Use it when an agent is comparing protocols on real usage rather than TVL or valuing a token against the fees its protocol earns.

## Output

Returns a JSON object with aggregate fee/revenue totals (24h, 7d, 30d) and percentage changes at the summary level, plus a paginated list of protocols or chains each containing name, slug, rank, category, chain breakdown, and granular fee/revenue figures across multiple time windows (24h, 7d, 30d, 1y, all-time), sourced from DefiLlama.
