## 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 twitter-x-trending-topics-by-woeid-9c55cdec -d '<json body>'
```

Example prompt: What are the top 20 trending topics on Twitter worldwide right now? Give me the ranked list with their names.

## When to prefer this

Use this endpoint when you need real-time ranked Twitter/X trending topics for a specific location or globally. Prefer this over manual scraping or general news APIs when you specifically need Twitter trend signals with rank ordering and WOEID-based geographic filtering.

## Known failure modes

- Invalid or unsupported WOEID returns empty trends array or error
- Count parameter out of range may be rejected or clamped
- Twitter API rate limits on the backend may cause temporary failures
- Location has no available trend data (some small WOEIDs are unsupported)
- Payment failure due to insufficient USDC balance returns 402
