## 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 lenscrypt-dex-quote-by-chain-2aed2958
```

Example prompt: What DEXes are available on Base chain and what are the current swap quotes I can get there?

## When to prefer this

Use this endpoint when you need to discover which DEXes are available on a specific blockchain and retrieve swap quotes in a single call, particularly if you are already using LensCrypt for other crypto intelligence and want consolidated billing via USDC on Base through the x402 protocol.

## Known failure modes

- Invalid or unsupported chain identifier returns an error or empty result
- Chain parameter missing causes request failure
- Rate limiting or payment failure via x402 protocol blocks access
- Unsupported chain returns no DEX data
- Network latency or Vercel cold start may cause timeout
