## 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 defi-protocol-tvl-lookup-via-defillama-233d1ed2
```

Example prompt: What's the current total value locked for Aave v3 — can you give me the breakdown by chain too?

## When to prefer this

Use this endpoint when you need current TVL data for a specific DeFi protocol identified by its DefiLlama slug, especially when you need the per-chain breakdown. Prefer this over generic DeFi data APIs when you specifically need DefiLlama-sourced TVL metrics for a named protocol.

## Known failure modes

- Unknown or misspelled protocol slug returns an error or empty result
- Protocol not tracked by DefiLlama returns no data
- Network timeout or DefiLlama upstream unavailability
- Payment of 0.005 USDC not provided returns 402 Payment Required

## How this service works

Total value locked for any DeFi protocol with per-chain breakdown via DefiLlama, by protocol slug such as aave-v3 or uniswap. defi tvl, protocol tvl, total value locked, defillama tvl, protocol metrics Accepts payment on Base or Solana — either network works.

## Output

Returns the total value locked (TVL) in USD for the specified DeFi protocol, along with a per-chain breakdown showing how much is locked on each individual blockchain (e.g. Ethereum, Arbitrum, Optimism).
