## 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-by-protocol-24h-7d-all-or-single-chain-d41b8482 -d '<json body>'
```

Example prompt: Show me the top 20 DEX protocols ranked by 24h and 7d trading volume on Ethereum — I want to see which ones are most active right now.

## When to prefer this

Choose this endpoint when you need a ranked, multi-protocol view of DEX trading activity — especially when comparing protocols head-to-head or monitoring volume trends across 24h and 7d windows. Prefer it over CEX volume endpoints when you specifically need on-chain decentralized exchange data. Use the chain filter when you only care about a specific L1 or L2 ecosystem.

## Known failure modes

- Invalid chain name returns empty results or error — chain identifiers must match supported chain names
- Limit out of range (>100 or <1) returns a validation error
- Payment failure (x402) if USDC balance is insufficient
- Upstream data lag may cause stale volume figures during off-hours
- No data for obscure or unsupported chains
