Why it exists

YouTube trend data, without the plumbing

The official YouTube Data API is built for metadata: videos, channels, playlists. It does not tell you how often people search for a topic, and it bills you in quota units that differ per endpoint. Trends API gives you the demand metric the official API omits, at a flat one-request-one-call rate.

Search interest on YouTube behaves differently from Google: tutorials, reviews and long-tail how-to queries dominate. Tracking a topic on both platforms tells you whether interest is informational (Google) or consumable content (YouTube), which matters for content planning.

FAQ

Common questions

What YouTube data does Trends API provide?

Keyword search volume over time (normalized 0-100), growth over 3M/6M/12M/5Y windows, and the live YouTube Trending feed of top videos right now.

How is this different from the YouTube Data API?

The YouTube Data API returns video and channel metadata but no search-interest metric. Trends API gives you the demand side: how often people search for a topic, on a normalized scale you can compare against TikTok, Google and 13 other sources.

Do I need a Google Cloud project?

No. One Trends API key, one POST endpoint, no OAuth and no quota-unit accounting.

How fresh is the data?

The trending feed updates continuously through the day. Keyword series are pulled on demand at request time; every response carries its own timestamp.

Can I track a topic across YouTube and TikTok together?

Yes. Make one get_growth call per source with the same keyword and compare the percentages directly; both are on the same normalized scale.
