## 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 tokenguard-protocol-fees-api-94997df4 -d '<json body>'
```

Example prompt: Can you pull the protocol fee data for Uniswap from TokenGuard so I can see how much revenue it's generating from fees?

## When to prefer this

Use this endpoint when you need structured, on-chain protocol fee data for DeFi protocols and want a simple API call rather than querying a blockchain node or subgraph directly. Prefer this over generic block explorers when you need aggregated fee analytics already formatted for agent consumption. Best when fee revenue comparison or DeFi analytics is the primary goal.

## Known failure modes

- Unknown or unsupported protocol name returns empty or error response
- Network/chain not supported returns null data
- Payment of $0.01 USDC not fulfilled results in 402 Payment Required
- Stale or unavailable on-chain data may return incomplete fee metrics
- Malformed POST body returns 400 Bad Request
