## 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 omnicall-defi-protocol-tvl-lookup-9d73dd05
```

Example prompt: Can you pull the live TVL, chain, and category for the Lido protocol right now so I can check its health for my DeFi portfolio?

## When to prefer this

Use this endpoint when an AI agent needs quick, keyless, pay-per-call access to live DeFi protocol TVL and metadata without setting up API keys or accounts — ideal for DeFi portfolio agents, allocation monitors, or any workflow that needs on-demand protocol health checks for protocols like Aave, Uniswap, or Lido.

## Known failure modes

- Unknown or misspelled protocol slug returns 404 or empty result
- DefiLlama upstream outage causes stale or unavailable data
- Payment failure on Base/Solana results in 402 error and no data returned
- Rate limiting or payment processing delay causes timeout

## How this service works

Live DeFi protocol TVL by chain + category & links (DefiLlama) — pass a protocol slug like 'aave', 'uniswap', 'lido'. For DeFi, portfolio and research agents. Pay-per-call USDC, no key.

## Output

Returns live protocol data sourced from DefiLlama including total value locked (TVL) in USD, the blockchain chain(s) the protocol operates on, and its DeFi category (e.g. lending, DEX, liquid staking).
