## 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 ragradar-dex-list-by-chain-db1f80b4
```

Example prompt: Can you pull up all the DEXes available on Base from RagRadar so I know which decentralized exchanges I can route trades through on that chain?

## When to prefer this

Use this endpoint when you need to discover which DEX protocols are active and supported on a specific chain (Base, Arbitrum, or Solana) before routing a swap, analyzing liquidity, or building a DeFi workflow. Prefer this over manual research or general web search when you need structured, up-to-date DEX enumeration per chain.

## Known failure modes

- Invalid or unsupported chain identifier returns error or empty list
- Chain parameter missing causes 400 bad request
- Payment not included or insufficient results in 402 Payment Required
- Network timeout or upstream analytics service unavailable returns 5xx
- Unsupported chain names not in Base/Arbitrum/Solana set may return empty or error

## How this service works
