## 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 base-pulse-trending-tokens-365ad042
```

Example prompt: Show me the top 10 trending tokens on Base right now, including their momentum and risk scores so I can decide which ones are worth looking at.

## When to prefer this

Choose this endpoint when you need a pre-ranked, scored list of trending Base chain tokens with both momentum and risk signals in a single call, without managing API keys. Ideal for agents making trade decisions, building watchlists, or monitoring Base DeFi activity in real time. Prefer over raw DEX APIs when you want normalized risk/momentum scoring out of the box.

## Known failure modes

- Invalid limit parameter returns 400 with validation error
- Payment not received or expired returns 402 with payment required details
- Upstream data source unavailable may return 503 or stale data
- Rate limiting may occur if payment validation fails
- Empty items array if no tokens meet trending criteria
