Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x-data-gateway-defillama-tvl-lookup-aac81196
```

Example prompt: What's the current total value locked for Aave? Look it up using the slug 'aave' from DefiLlama.

## When to prefer this

Choose this endpoint when you need real-time TVL data for a specific DeFi protocol by its DefiLlama slug, especially within an agent workflow that also uses X/Twitter data or Base chain intel from the same gateway. Ideal for pay-per-call usage without managing API keys, using USDC micropayments via x402.

## Known failure modes

- Invalid or unknown slug returns empty or error response
- DefiLlama upstream unavailability causes failed fetch
- Missing required 'slug' query parameter causes validation error
- Rate limiting or payment failure (x402) blocks the request

## How this service works

Current TVL for a protocol slug from DefiLlama free API. e.g. GET /v1/defi/tvl?slug=aave

## Output

Returns a JSON object containing TVL data for the specified DeFi protocol as sourced from DefiLlama, including aggregate and possibly chain-specific TVL figures.
