## 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 pyfile-toolkit-dex-token-price-liquidity-019fb558
```

Example prompt: What's the current DEX price and liquidity for WETH across chains?

## When to prefer this

Use this endpoint when you need real-time DEX-sourced token prices and liquidity data across multiple chains, particularly for DeFi workflows, arbitrage detection, portfolio valuation, or on-chain analytics. Prefer this over centralized exchange APIs when you need decentralized, on-chain pricing data.

## Known failure modes

- Unknown or unrecognized token symbol returns empty or error response
- Invalid contract address format causes a bad request error
- Token with no DEX liquidity returns zero or null liquidity data
- Network or upstream DEX data provider outage causes timeout or 503
- Misspelled token symbol returns no results

## How this service works

DEX token price and liquidity across chains. ?q=WETH or ?q=<token address>

## Output

Returns real-time DEX price and liquidity information for the queried token, including current price, liquidity pool depth, and relevant chain data, sourced from decentralized exchanges across multiple chains.
