## 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 three-ws-market-chains-tvl-lookup-c298e625
```

Example prompt: Can you pull the current TVL breakdown across all blockchain chains — I want to see which networks have the highest market share and total value locked?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call snapshot of cross-chain TVL and market share data without requiring a subscription. Best suited for agents that need lightweight DeFi market context, chain comparison, or liquidity signals at minimal cost ($0.001 USDC).

## Known failure modes

- Invalid or malformed properties query parameter returns error
- Payment not sent (x402 payment required, $0.001 USDC) results in 402 response
- Service unavailable or upstream data feed outage returns 5xx
- Empty or stale chain data if indexer is behind

## How this service works

Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.

## Output

A JSON object containing an array of chain objects (each with name, TVL in USD, market share percentage, and token symbol) plus the aggregate total TVL across all chains.
