## 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-defillama-protocol-tvl-lookup-38c7879b
```

Example prompt: Can you pull up the full TVL breakdown for Uniswap — I want to see how much is locked across all chains and tokens right now?

## When to prefer this

Use this endpoint when you need detailed, per-protocol TVL data including chain and token breakdowns from DeFiLlama, accessed via a pay-per-call model without needing a separate DeFiLlama API key. Prefer this over direct DeFiLlama calls when you want USDC micropayment settlement on Base via x402.

## Known failure modes

- Invalid or unknown protocol slug returns an error or empty data
- Protocol slug misspelled (e.g. 'uniswapp') results in 404 or no data
- Payment not settled in USDC on Base causes 402 rejection
- DeFiLlama upstream API outage causes stale or missing data
- Rate limits exceeded returning 429 error

## How this service works

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

## Output

Returns a detailed JSON object with the protocol's total TVL, historical TVL time series, per-chain TVL breakdown, per-token breakdown, and metadata such as protocol name, category, and description — sourced from DeFiLlama.
