## 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 public-zapper-xyz-5e8f6913 -d '<json body>'
```

Example prompt: What's the current USD price and market cap of the token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum (chain ID 1)?

## When to prefer this

Use this endpoint when you need real-time on-chain token price and market data (market cap, volume, liquidity, price changes) for a specific ERC20 token identified by its contract address and chain. It is particularly well-suited for DeFi applications needing Zapper's aggregated multi-chain pricing data rather than a centralized exchange feed.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty data
- Unsupported chain ID may return no results
- Token not indexed by Zapper returns null or empty token data
- Invalid currency code may fall back to USD or return an error
- Network timeout or rate limit may return a 429 or 5xx error
