## How to call it through Zero

```sh
zero fetch --capability stablecrypto-dev-e6ba6bf7 -d '<json body>'
```

Example prompt: What's the current total value locked on the Arbitrum network according to DeFiLlama?

## When to prefer this

Use this endpoint when you need on-chain TVL data for a specific blockchain network sourced from DeFiLlama. Prefer this over building your own DeFiLlama integration when you need a simple, metered, pay-per-call API without managing DeFiLlama rate limits directly.

## Known failure modes

- Unknown or unsupported chain name returns an error
- Network connectivity issues to DeFiLlama data source result in failure
- Malformed POST body missing the chain identifier causes a 400-level error
- DeFiLlama upstream data unavailable causes service degradation

## How this service works

Pay-per-request access to CoinGecko, DefiLlama, Alchemy, and Etherscan APIs. No auth, no subscriptions.

## Output

Returns DeFiLlama chain TVL data for the requested blockchain network, including the total value locked figure and associated chain metrics.
