YoTrends
Trend research for YouTube and TikTok through the YoTrends REST API: what is trending now by platform and region, the creators that trend most, and content categories with their trend weight, subcategories and trendlines. It runs on FlyMyAI's YoTrends plan, so there is nothing to set up. Connect your own YoTrends API key to use your plan instead.
What it can do
| Method | What it does |
|---|---|
yotrends_trend_videos | Trending videos of one platform (youtube or tiktok) in a region: a window of 1-30 days, sort, language filters and up to 100 videos a page. |
yotrends_trend_influencers | The creators that appear in trends most often on one platform in a region, paged. |
yotrends_categories | Content categories with their trend weight in a region - which niches grow. |
yotrends_category_subcategories | The subcategories of one category, rising first. |
yotrends_category_trendline | A category's trendline over time - is the niche growing or fading. |
All of it is public trend data, read only. A call costs compute time. On FlyMyAI's plan every user has a monthly share of API calls, and the error says when it is used up. With your own key the share does not apply and YoTrends counts the calls against your plan.
To keep a list of trends you follow, save the results in FlyMyAI - in your files or in the run's result. YoTrends' own tracked topics are not part of this tool.
How to get credentials
None on FlyMyAI Cloud - the tool runs on FlyMyAI's YoTrends plan, so just enable it. To use your own YoTrends plan instead:
- Sign up at yotrends.ai on the Team or Agency plan - the REST API is on those plans.
- Open Settings and copy your API key.
It is not the MCP token that starts with
ytm_. - Paste it into the optional field below.
Fields to fill in FlyMyAI
| FlyMyAI field | Where it comes from |
|---|---|
YOTRENDS_API_KEY (optional) | YoTrends -> Settings -> API key (Team and Agency plans); leave empty to use FlyMyAI's plan |
Troubleshooting
- HTTP 401 - YoTrends rejected the API key. Copy it again from YoTrends Settings and update the field.
- HTTP 403 - the plan does not include the REST API (it is on Team and Agency). Reconnecting does not change it.
- HTTP 429 - YoTrends rate limit: wait and retry. When the plan's API calls for the billing cycle are used up, the error says when they renew. On FlyMyAI's plan, connect your own key to go on before that.
- "This month's share of FlyMyAI's YoTrends plan is used up" - connect your own API key, or wait for the next month.
- "That is a YoTrends MCP token (ytm_...), not an API key" - this tool takes the REST API key from YoTrends Settings, not the MCP token.
- Region refused - use a two-letter region code such as US.
