Example prompt: What are the trending TikTok hashtags in the United States over the past 30 days? I want to see which tags are most popular right now.

## When to prefer this

Use this endpoint when you need country-specific TikTok hashtag trend data for a defined recent time window (7, 30, or 120 days). It is ideal for social media marketers, content strategists, and brand analysts who want data-driven hashtag recommendations without scraping TikTok directly. Prefer this over generic social trend APIs when TikTok-specific regional hashtag rankings are required.

## Known failure modes

- Invalid or unsupported ISO 3166-1 alpha-3 country code returns an error or empty result
- Invalid periodDays value (anything other than 7, 30, or 120) may return an error or fallback
- No trending data available for a sparsely-used TikTok market returns an empty list
- Payment failure or insufficient USDC balance blocks the request
- Network timeout or upstream TikTok data unavailability causes a 5xx error
