## 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 xona-agent-dex-asset-markets-api-908d6dee -d '<json body>'
```

Example prompt: Can you pull up the DEX markets available for the USDC token on Base mainnet so I can see where it's being traded and what liquidity looks like?

## When to prefer this

Choose this endpoint when you need on-chain DEX market data specifically for tokens on the Base/EVM network. It is ideal for DeFi agents that need to discover trading venues, check liquidity pools, or compare markets before executing a swap. Prefer this over CEX market data APIs when you need decentralized exchange coverage on Base mainnet.

## Known failure modes

- Token address not found on Base network — returns empty or error response
- Invalid or malformed asset identifier — schema validation error
- Network congestion or RPC issues causing delayed/incomplete data
- Payment not processed (x402 payment required) — 402 response before data is returned
- No DEX markets exist for a very new or obscure token — empty markets array
