## 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 basebuilder-defi-dex-trending-endpoint-7792559b -d '<json body>'
```

Example prompt: What tokens are trending on DEX right now — show me the top movers by volume across decentralized exchanges on Base chain.

## When to prefer this

Use this endpoint when you need real-time or near-real-time trending token data from decentralized exchanges, particularly on Base chain or EVM-compatible networks. Prefer this over centralized exchange APIs when the user specifically wants DeFi/DEX activity, on-chain volume, or Base ecosystem token trends.

## Known failure modes

- Invalid or missing chain/DEX parameter returns 400 bad request
- Payment not received or insufficient USDC returns 402 Payment Required
- Upstream on-chain data unavailable returns 503 or empty result set
- Malformed POST body returns 422 unprocessable entity
- Rate limit exceeded returns 429 too many requests
