## 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 api-strale-io-0f4304c4
```

Example prompt: What's the current TVL for Aave — and which chains is it deployed on and is it audited?

## When to prefer this

Use this endpoint when you need current TVL, chain distribution, category, or audit information for any DeFi protocol. Covers 7,000+ protocols via DeFi Llama, making it the broadest DeFi protocol metadata source available. Prefer over manual DeFi Llama web scraping or on-chain queries when you need structured, aggregated cross-chain TVL data quickly.

## Known failure modes

- Unknown protocol slug returns 404 or empty result
- Protocol name ambiguity may return wrong protocol if slug is not exact
- Stale TVL data if DeFi Llama upstream is delayed
- Rate limiting or payment failure returns 402
- Network timeout for obscure protocols with complex chain distributions

## How this service works

Get the current Total Value Locked (TVL), chain distribution, category, audit status, and metadata for any DeFi protocol. Covers 7,000+ protocols across 500+ chains via DeFi Llama.

## Output

Returns a structured object containing the protocol's current Total Value Locked in USD, a breakdown of TVL across each chain, the protocol's DeFi category (e.g. lending, DEX), audit status, and general metadata such as description, website, and token info. Coverage spans 7,000+ protocols across 500+ chains via DeFi Llama.
