## 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 vextorium-defi-protocol-lookup-11935997 -d '<json body>'
```

Example prompt: Look up the current TVL, category, supported chains, and social links for Aave — I want to see how it's been trending over the last day and week.

## When to prefer this

Use this endpoint when you need structured, up-to-date DeFi protocol metrics — particularly TVL and its recent trend — sourced from DefiLlama, for any named protocol. Prefer this over manual DefiLlama scraping or generic web search when you need machine-readable output including category, chains, token, and social handles in a single call.

## Known failure modes

- Unknown or misspelled protocol name returns no match or error
- Protocol slug not recognized by DefiLlama results in null/empty response
- Network timeout or upstream DefiLlama API unavailability
- Newly launched protocols may not yet be indexed
