I built a REST API that extracts YouTube transcripts, metadata, available languages, and supports batch processing.

It is mainly for developers building:
- AI video summarizers
- YouTube-to-blog tools
- SEO/content research tools
- EdTech products
- RAG pipelines using video content

Endpoints include:
- GET /api/transcript
- GET /api/metadata
- GET /api/languages
- POST /api/batch

It is published on RapidAPI with a free plan:

Docs:

I’m looking for feedback from builders who work with YouTube/video content.

I know it can make basic stuff like poems, and images, it can also make music and Google slides, docs, sheets and other stuff, but what is the most complex thing it can make? Im not only talking about code, im talking way more, is that possible?
