## How to call it through Zero

```sh
zero fetch --capability api-web3identity-com-e45cabb7
```

Example prompt: What's the current total value locked in Uniswap across all chains? Pull the latest TVL figure from DefiLlama.

## When to prefer this

Use this endpoint when you need real-time or near-real-time TVL data specifically for Uniswap and want DefiLlama as the authoritative source. Prefer this over generic DeFi APIs when you need the TVL broken down by chain and trust DefiLlama's aggregation methodology.

## Known failure modes

- DefiLlama upstream unavailable — returns 5xx or empty response
- Protocol data temporarily stale — TVL may be slightly delayed
- Rate limit exceeded if called at high frequency
- Payment failure if x402 payment header is missing or invalid — returns 402
