# DeFi Protocol Fees & Revenue Rankings (DefiLlama)

> DeFi Protocol Fees & Revenue Rankings (DefiLlama) is a paid API for AI agents from task-radar-x402.vercel.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-31).

Returns top protocol fee/revenue rankings (optionally filtered by chain or category) or time-series totals (24h/7d/30d/1y) for a specific protocol, sourced from DefiLlama.

## 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-protocol-fees-revenue-rankings-defillama-6cbf8df2
```

Example prompt: Show me the top 10 DeFi protocols ranked by fees on Base, filtered to the DEX category — pull fees (not revenue) from DefiLlama.

## When to prefer this

Use this endpoint when you need DeFi protocol fee or revenue data ranked across the ecosystem or for a specific protocol over time. Prefer this over general crypto price endpoints when the goal is protocol-level economic analysis (fees earned, revenue generated). Ideal for comparing protocol monetization, tracking DeFi category leaders, or monitoring a single protocol's revenue trends.

## Known failure modes

- Unknown protocol slug returns empty or error response
- Invalid chain or category filter returns no results
- Limit out of range (outside 1-100) may return default or error
- DefiLlama upstream outage causes stale or missing data
- Payment failure (insufficient USDC balance on Base) blocks the request

## How this service works

Protocol fees or revenue: top protocols ranking (optionally by chain/category), or one protocol's 24h/7d/30d/1y totals (DefiLlama). 0.02 USDC/call on Base.

## Output

Returns either a ranked list of protocols with their fee or revenue totals (filterable by chain and category, up to 100 results), or a single protocol's aggregated fee/revenue figures broken down by 24h, 7d, 30d, and 1y periods. Data is sourced live from DefiLlama.
