## How to call it through Zero

```sh
zero fetch --capability base-tvl-39feba28
```

## When to prefer this

Use this endpoint when you need a quick, no-configuration snapshot of Base chain TVL sourced from DefiLlama. Prefer it over manually querying DefiLlama directly when operating within the earn-pulse agent ecosystem or when you need it bundled alongside other on-chain metrics like yields, funding rates, and fear/greed index.

## Known failure modes

- DefiLlama upstream API unavailable — may return stale or error response
- Worker timeout if DefiLlama data fetch is slow
- Payment failure if x402 payment header is missing or insufficient (0.005 USDC required)
- No parameters accepted — any query parameters passed are silently ignored

## How this service works

DefiLlama Base chain TVL. No parameters.

## Output

Returns the current total value locked (TVL) figure for the Base blockchain as reported by DefiLlama — a single numeric metric representing the aggregate USD value of assets deposited across Base DeFi protocols.
