## 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-defillama-via-task-radar-x402-3a0b6dfd
```

Example prompt: Show me the top 10 DEXes by trading volume on Solana — I want to see their 24h, 7d, and 30d numbers ranked.

## When to prefer this

Use this endpoint when you need ranked DEX trading volume data across multiple time horizons (24h/7d/30d) with optional chain filtering. Prefer this over general DeFi endpoints when the goal is comparing DEX activity or identifying which exchange dominates a specific chain. This endpoint is specifically sourced from DefiLlama and costs only $0.01 USDC per call on Base.

## Known failure modes

- Invalid chain name returns empty results or error
- Limit out of range (>100 or <1) may return default or error
- DefiLlama upstream outage causes failure or stale data
- Payment failure on Base blocks the call from being processed

## How this service works

DEX trading volume ranking 24h/7d/30d, optionally by chain (DefiLlama). 0.01 USDC/call on Base.

## Output

A ranked list of decentralized exchanges with their trading volume figures across 24h, 7d, and 30d time windows, optionally scoped to a specific blockchain. Includes DEX names, chain info, and volume metrics for comparison.
