## 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 basebrain-dex-pairs-8860e47b -d '<json body>'

## When to prefer this

Choose this endpoint when you need to look up DEX trading pairs, liquidity pools, or market pair metadata for cryptocurrency tokens on decentralized exchanges. Prefer this over centralized exchange APIs when your use case is specifically DeFi or on-chain trading data.

- No pairs found for the queried token returns empty data array
