## 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-697b4100
```

Example prompt: What's the current TVL and chain-by-chain breakdown for Aave V3 on DeFiLlama?

## When to prefer this

Use this endpoint when you need detailed TVL data and chain-level breakdown for a specific DeFi protocol. Prefer this over general market data APIs when you specifically need DeFiLlama's protocol-level TVL tracking, including multi-chain distribution and token composition. Ideal for protocol research, DeFi dashboards, and competitive analysis of liquidity across protocols.

## Known failure modes

- Invalid or unknown protocol slug returns an error or empty data
- Network timeout if DeFiLlama upstream is slow
- Protocol slug must match DeFiLlama's canonical slug format (e.g. 'aave-v3', not 'aave v3'
- Payment required error if x402 payment header is missing or insufficient

## 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 JSON object with the protocol's total TVL, TVL broken down by chain and token category, protocol metadata (name, description, chains supported), and historical TVL data points as tracked by DeFiLlama.
