## How to call it through Zero

```sh
zero fetch --capability alpha-palmvox-com-d1c0d7ea
```

Example prompt: What tokens and DeFi pools are trending on Base right now, and what's the overall market sentiment?

## When to prefer this

Use this endpoint when you specifically need trending token and DeFi yield data scoped to the Base blockchain ecosystem. Prefer this over generic crypto trending APIs when Base-native protocols and tokens are the focus, or when you want a combined view of price momentum, yield opportunities, and sentiment in a single call.

## Known failure modes

- Stale data if scan cycle has not recently completed — check lastUpdated field
- Confidence levels may be LOW for volatile tokens — interpret trending data cautiously
- Payment failure (x402) if USDC balance insufficient — returns 402 status
- No Base-specific data available if indexing is temporarily down — empty trending array

## How this service works

What's trending on Base right now — top moving tokens, hottest DeFi pools, and social buzz. Updated every scan cycle. Zero competition on Bazaar for Base-specific trending.

## Output

Returns an array of trending tokens with price, percent change, and confidence level; an array of hot yield opportunities with protocol name, APY, and TVL; an overall market sentiment string (e.g. 'neutral'); and a lastUpdated ISO timestamp. Also includes a link to a free track record endpoint and references to sibling endpoints.
