## 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 booaip-tvl-lookup-6428a622
```

Example prompt: What's the current TVL for Aave right now, and how has it changed over the past 7 days?

## When to prefer this

Use this endpoint when an AI agent needs real-time or near-real-time TVL data for a specific DeFi protocol and can pay $0.01 USDC per call via x402 on Base. Ideal for agents doing DeFi research, portfolio analysis, or protocol comparison without a large data subscription. Prefer this over general web search when structured, machine-readable numeric TVL data with a 7-day trend is needed.

## Known failure modes

- Protocol not found or unsupported — 'found' field returns false
- Invalid or missing protocol name in request body — may return 4xx error
- Payment failure via x402 if USDC balance is insufficient — 402 Payment Required
- Rate limiting or upstream data unavailability — 5xx error
- Network timeout if upstream DeFi data source is slow

## How this service works

DeFi protocol TVL, chains and 1d/7d change (DefiLlama).

## Output

A JSON object with a boolean 'found' flag, the protocol's current TVL in USD as a number, the protocol name, and the 7-day percentage change in TVL. Example: {found: true, tvlUsd: 1000000000, protocol: 'Aave', change7dPct: 2.5}.
