## 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 coin-railz-token-price-lookup-0c30a52c -d '<json body>'
```

Example prompt: What's the current price, 24-hour change, and market cap for the token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum?

## When to prefer this

Use this endpoint when you need real-time token price data including 24h change, volume, and market cap for a specific token identified by its on-chain contract address and blockchain network. Prefer this over generic market APIs when you need DEX-level coverage for tokens not listed on major centralized exchanges, or when you want data aggregated from both CoinGecko and DEX Screener simultaneously.

## Known failure modes

- Invalid or unrecognized contract address returns an error or empty data
- Unsupported chain identifier causes a validation error
- Token not indexed by CoinGecko or DEX Screener returns no data
- Payment of $0.25 USDC not processed results in HTTP 402 response
- Network timeout from upstream data provider causes delayed or failed response
