# DEX Trading Volume Rankings by Protocol

> DEX Trading Volume Rankings by Protocol is a paid API for AI agents from crypto.apitoll.cloud, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Returns decentralized exchange trading volumes ranked by protocol, with 24h and 7d USD volume, percent changes, and supported chains, optionally filtered to one blockchain.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 dex-trading-volume-rankings-by-protocol-a3578f99
```

Example prompt: Can you show me the top 20 decentralized exchanges ranked by trading volume on the Base chain, including their 24-hour and 7-day USD volumes and how much those volumes have changed?

## When to prefer this

Use this endpoint when you need protocol-level DEX volume rankings across all chains or a specific chain, with percent-change context over 1d/7d windows. Prefer this over general crypto market endpoints when the focus is specifically on decentralized trading activity and protocol comparison rather than token prices or DeFi TVL.

## Known failure modes

- Invalid chain name returns empty results or an error — must use supported chain slugs like 'ethereum', 'base', 'solana', 'arbitrum'
- Limit value outside 1–100 range is rejected
- DefiLlama upstream outage may cause stale or missing data
- Payment failure (x402) returns 402 status before data is served

## How this service works

Decentralized exchange (DEX) trading volume ranked by protocol: 24-hour and 7-day volume in USD with 1d/7d change, plus the chains each DEX runs on. Pass ?chain=base to scope to one chain. See where on-chain trading is happening across Uniswap, Curve, Raydium, PancakeSwap and more. Sourced from DefiLlama.

## Output

A JSON array of DEX protocols ranked by volume, each with protocol name, 24h USD volume, 7d USD volume, 1-day and 7-day percent changes, and the list of chains each DEX operates on. Also includes aggregate totals (total24hUsd, total7dUsd), the chain filter applied, the count of results, and source attribution (DefiLlama).
