## 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 defillama-tvl-lookup-278c816b -d '<json body>'
```

Example prompt: What's the current total value locked for Uniswap? Use the protocol slug 'uniswap' to look it up.

## When to prefer this

Use this endpoint when you need the current TVL for a single, specific DeFi protocol by its DeFiLlama slug. Prefer this over scraping DeFiLlama directly or using general crypto data APIs that may not provide TVL. Ideal for agents building DeFi dashboards, comparing protocol sizes, or monitoring a specific protocol's liquidity health.

## Known failure modes

- Invalid or unknown protocol slug returns an error or null
- Protocol slug is case-sensitive or formatted incorrectly causing no match
- DeFiLlama upstream API is unavailable causing a timeout or 5xx error
- Protocol has been delisted or renamed, returning stale or missing data

## How this service works

## Output

A single numeric value representing the current TVL of the requested protocol in USD, returned as a plain number (e.g. 5234891234.12).
