## 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 basebuilder2-crypto-dex-screener-endpoint-f862d22d -d '<json body>'
```

Example prompt: Can you pull up the current DEX Screener data for the PEPE/WETH trading pair on Ethereum — I want to see the price, 24h volume, and liquidity?

## When to prefer this

Choose this endpoint when you need real-time DEX trading data including prices, volumes, and liquidity for tokens traded on decentralized exchanges. Prefer it over CEX-focused APIs when the token is only listed on DEXes or when on-chain liquidity data is specifically needed.

## Known failure modes

- Token or pair not found on DEX Screener — returns empty or null result
- Invalid contract address format causes request error
- Chain ID not supported returns no data
- Payment failure (402) if USDC balance is insufficient
- Rate limiting or upstream DEX Screener API outage causes timeout
