## 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`):

```

Example prompt: What's the current USD price and 24-hour change for the token at contract address 0x4200000000000000000000000000000000000006 on Base?

## When to prefer this

Choose this endpoint when you need price data for tokens identified by contract address rather than ticker symbol, especially long-tail or newly launched DEX tokens not listed on centralized exchanges. Ideal when querying across Base, Ethereum, Polygon, Arbitrum, Optimism, BSC, Avalanche, Solana, or World Chain and needing batch lookups of up to 30 contracts at once.

## Known failure modes

- Invalid or unrecognized contract address returns an error or null price
- Unsupported chain value returns a validation error
- Exceeding 30 addresses in a single request returns an error
- Token with no liquidity or trading history may return null or zero price
- Network issues may cause timeouts for some chains

## How this service works

USD price and 24h change for any token by contract address (up to 30 at once) on Base, Ethereum, Polygon, Arbitrum, Optimism, BSC, Avalanche, Solana or World Chain. Covers long-tail DEX tokens that ticker-based price feeds miss.

## Output

Returns the current USD price and 24-hour percentage change for each requested token contract address, covering tokens traded on decentralized exchanges that may not appear on ticker-based price feeds.
