## 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-5330df4b
```

Example prompt: What's the current total value locked in Aave right now? Pull it from DefiLlama.

## When to prefer this

Use this endpoint when you need a single DeFi protocol's current TVL and want a lightweight, paid-per-call lookup without managing DefiLlama API keys or rate limits yourself. Ideal for agents that need real-time DeFi protocol size data as part of a broader financial analysis or monitoring workflow.

## Known failure modes

- Unknown or misspelled protocol slug returns an error or null TVL
- DefiLlama API downtime causes fetch failure
- Protocol slug format mismatch (e.g. using display name instead of slug like 'aave-v3' vs 'aave')
- Network timeout from Render cold start on first request

## How this service works

Current TVL (total value locked) of a specific DeFi protocol, source DefiLlama. Parameter: ?protocol=<slug> (default: aave).

## Output

A JSON object containing the protocol slug, TVL in USD as a number, currency (USD), the source DefiLlama API URL, and a timestamp of when the data was fetched. Example: {protocol: 'aave', tvl_usd: 21000000000, currency: 'USD', source: 'https://api.llama.fi/tvl/aave', fetched_at: '2026-09-01T12:00:00.000Z'}.
