## 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 foundry-defi-tvl-lookup-2869d22e -d '<json body>'
```

Example prompt: What's the current total value locked for Base chain right now? Pull the TVL from DefiLlama.

## When to prefer this

Use this endpoint when you need real-time DeFi TVL data sourced from DefiLlama for a specific chain (e.g. Base, Ethereum, Polygon), a protocol (e.g. Aave, Uniswap, Compound), or want a ranked list of top chains. Prefer this over general web search when you need a structured, numeric TVL figure ready for computation or reporting.

## Known failure modes

- Unknown chain or protocol slug returns an error or null TVL
- DefiLlama upstream API unavailable causes fetch failure
- Misspelled protocol name (e.g. 'aav' instead of 'aave') may return no results
- Very new or obscure protocols may not be tracked by DefiLlama
- Rate limiting or payment failure returns 402 status

## How this service works

DeFi TVL from DefiLlama: total value locked for a chain or protocol, or the top chains. Input: 'Base', 'aave' or 'top'.

## Output

Returns a JSON object containing the chain or protocol name, TVL in USD as a numeric value, the token (if applicable), and the source (DefiLlama). For 'top' input, returns a ranked list of chains with their TVL figures.
