## 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-quotes-by-chain-21a7f00a
```

Example prompt: What decentralized exchanges does RagRadar support on Base? I want to know which DEX venues are available before I request a swap quote.

## When to prefer this

Use this endpoint when you need to discover which DEX venues RagRadar can query for a particular blockchain before requesting swap quotes or price data. Prefer this over generic DEX lists when you are already using RagRadar's x402-gated on-chain intelligence APIs and need to enumerate valid sources programmatically.

## Known failure modes

- Unsupported or misspelled chain name returns an error or empty list
- Missing chain path parameter results in a 404 or bad request
- Service unavailable returns a non-200 status
- x402 payment not fulfilled results in 402 Payment Required response
