## 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 vape-dex-volumes-c530d316
```

Example prompt: Show me all the DEX venues on Base ranked by trading volume, including their logos so I can see which exchanges are most active right now.

## When to prefer this

Use this endpoint when you need a per-venue breakdown of DEX trading volumes on a specific EVM-compatible chain (especially Base). Prefer this over chain_overview when you need granular exchange-level data rather than aggregate TVL, and over chain_protocols when you specifically care about trading activity rather than total value locked.

## Known failure modes

- Unsupported chain slug returns empty result or error
- Payment of $0.01 USDC not fulfilled results in 402 Payment Required
- Chain with no tracked DEX data returns empty array
- Network timeout if upstream data provider is slow

## How this service works

VAPE dex_volumes — DEX trading volume on a chain by venue, each with its logo (default Base) — real trading activity across the chain's exchanges.

## Output

A list of decentralized exchanges (DEXes) on the specified chain (default: Base), each with its trading volume and logo URL, ranked or grouped by venue — enabling a ranked view of real trading activity across the chain's exchanges.
