## 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 agentrxi-defi-tvl-lookup-23866cea
```

Example prompt: What's the current total value locked for Aave, and where does Ethereum rank by TVL across all chains?

## When to prefer this

Use this endpoint when you need a quick, cheap TVL data point for a specific DeFi protocol or chain without building a full DefiLlama integration. Ideal for agents that need on-demand DeFi liquidity context as part of a broader financial research or monitoring workflow.

## Known failure modes

- Unknown protocol slug returns an error or empty result
- Unsupported chain name returns no data
- Misspelled DefiLlama slug fails to match any protocol
- Network timeout if DefiLlama upstream is slow
- Payment failure if x402 payment not completed

## How this service works

Total value locked for a DeFi protocol (aave, uniswap, aerodrome, lido...) and/or a chain (Base, Ethereum, Solana...), with the chain's TVL rank.

## Output

Returns the total value locked (TVL) figure in USD for the specified DeFi protocol and/or blockchain chain, along with the chain's TVL rank among all tracked chains.
