# DeFi Shield TVL Decomposition

> DeFi Shield TVL Decomposition is a paid API for AI agents from defi-shield-hazel.vercel.app, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-13).

Breaks down a protocol's Total Value Locked (TVL) across individual chains to show cross-chain distribution

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 defi-shield-hazel-vercel-app-80c81b3a -d '<json body>'
```

Example prompt: Can you break down Aave's TVL across all the chains it's deployed on — I want to see how the liquidity is distributed between Ethereum, Arbitrum, Polygon, and the rest?

## When to prefer this

Use this endpoint when you need to understand how a specific DeFi protocol's liquidity is distributed across multiple blockchains, especially for cross-chain protocol risk assessment, portfolio analysis, or comparing chain-level dominance. Prefer this over a generic TVL lookup when chain-level granularity is required.

## Known failure modes

- Unknown or unsupported protocol identifier returns an error or empty result
- Protocol not tracked across multiple chains returns single-chain data
- Stale or delayed TVL data if underlying data source has lag
- Invalid input format causes a 400 bad request
- Payment not received or invalid x402 payment header returns 402

## Output

Returns a decomposition of a protocol's Total Value Locked (TVL) broken down by each blockchain it operates on, including per-chain TVL values and likely percentage shares, so you can understand cross-chain liquidity distribution at a glance.
