## How to call it through Zero

```sh
zero fetch --capability api-strale-io-7ce9c887
```

Example prompt: What are the fees and revenue for Aave V3 — give me the 24h, 7d, 30d, and all-time numbers.

## When to prefer this

Use this endpoint when you need structured fee and revenue metrics for any DeFi protocol across multiple time horizons. It is ideal for protocol comparison, due diligence, yield analysis, or tracking DeFi ecosystem revenue trends. The 7,000+ protocol coverage via DeFi Llama makes it the best choice for broad DeFi analytics without needing to integrate DeFi Llama directly.

## Known failure modes

- Unknown or misspelled protocol name returns an error or empty result
- Protocol exists on DeFi Llama but has no fee tracking data
- Rate limiting or payment failure returns 402 or 429 status
- Protocol slug differs from common name (e.g., 'uniswap-v3' vs 'uniswap') causing no match
- Newly launched protocols may have incomplete or missing historical data
