## 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 blockrun-ai-defillama-protocol-tvl-lookup-1b18f9c0
```

Example prompt: Pull up the full TVL breakdown for Aerodrome from DeFiLlama — I want to see how much is locked across chains and by token.

## When to prefer this

Use this endpoint when you need detailed, structured TVL data for a single DeFi protocol including chain-level and token-level breakdowns. Prefer this over generic DeFi data sources when you need DeFiLlama-sourced protocol analytics via a pay-per-call x402 model without setting up a DeFiLlama API key directly.

## Known failure modes

- Invalid or unknown protocol slug returns an error or empty data
- Protocol slug casing mismatch may cause lookup failure
- Network or upstream DeFiLlama API unavailability causes 5xx errors
- Payment not processed results in 402 response blocking data access

## How this service works

Detailed TVL + breakdown for a single protocol. Pass slug as `/v1/defillama/protocol/{slug}` (e.g. `aave`, `uniswap`).

## Output

A JSON object containing the protocol's total TVL, a breakdown by chain, a breakdown by token, historical TVL data, and other protocol-level metadata sourced from DeFiLlama.
