Blackcube

Turn public crypto and trading channels into a structured feed. Every post carries its tickers, any wallet or contract addresses, sentiment, views and reactions. Built for backtesting and channel comparison, not for following calls. No Telegram account needed.

Export a public channel straight to CSV, JSON, Excel or XML with one run. Flat, documented columns with no nulls where a value exists, ready for a spreadsheet or a database load. No Telegram account needed. Failures are free.

Hand it a list of websites and get back the business email addresses each one publishes, checked for deliverability and deduplicated to one row per company. Phone numbers and social profiles are included in the same row at no extra cost.

Pull the closed captions off any YouTube video - and not just one language. Each available caption track comes back separately with its language, whether it was human-written or auto-generated, and a ready-made WebVTT version, so localisation and accessibility checks stop being manual work.

Download ready-to-use subtitle files from any YouTube video, playlist or channel. Every result carries the finished SRT and WebVTT text alongside plain text, correctly timed and ready to drop into a player, an editor or a caption workflow. Batch a whole channel in one run.

Used by RAG builders and content teams that need YouTube as text, at scale. YouTube transcript API: send one URL or ten thousand, videos, playlists and channels mixed, and get clean timestamped text back in one pass. Structured JSON per row. You pay only for transcripts delivered.
