## 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 mcpfax-markets-defi-protocol-detail-3eddbe21
```

Example prompt: Can you pull up the full protocol details for Aave — TVL, fees, revenue, chain breakdown, all of it?

## When to prefer this

Use this endpoint when you need rich, protocol-specific DeFi metrics (TVL, fees, revenue, chain breakdown) for a single named protocol. Prefer this over the defi_protocols list endpoint when you already know which protocol you want and need deeper detail rather than a ranked overview.

## Known failure modes

- Unknown or misspelled protocol slug returns an error or empty result
- Protocol exists but has no recent on-chain data, resulting in null fields
- Network or upstream data source (e.g. DefiLlama) is unavailable, causing a timeout
- Payment failure on Base network results in 402 response before data is returned
