## How to call it through Zero

```sh
zero fetch --capability dex-token-price-liquidity-lookup-105211de
```

Example prompt: What's the current on-chain DEX price and liquidity for WETH right now?

## When to prefer this

Use this endpoint when you need real-time, on-chain DEX price and liquidity data for a token — especially when you have a contract address or symbol and need cross-chain DEX market data rather than centralized exchange prices. Prefer this over CEX price APIs when the token may not be listed on major centralized exchanges or when on-chain liquidity context is critical.

## Known failure modes

- Unknown or unrecognized token symbol returns empty or error result
- Invalid contract address format causes a bad request response
- Token exists on-chain but has no DEX liquidity, returning null or zero values
- Network congestion or RPC issues may cause stale or delayed data
- Missing required 'q' query parameter returns an error

## How this service works

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

## Output

Returns DEX market data for the queried token including current price, liquidity depth, trading volume, and relevant cross-chain data from decentralized exchange sources
