YouTube Channel Stats Extractor - Subscribers by Domain

company-checked

Once per company for which the discovery cascade completed and a non degraded channel row was produced, whether or not a channel was found. Does not fire on a degraded row.

profile-resolved

Once per company whose candidate channel URL passed the identity gate. Fires on the validation work, not on a populated subscriber cell.

follower-count-extracted

Once per channel where a numeric subscriber count was read off the public page. Does not fire when the owner has hidden the count, which reports not_extractable.

transcript-extracted

Once per video for which transcript TEXT was actually returned. A video with no caption track does not charge, and neither does a video whose caption track exists but whose content YouTube refused to serve. Never fires when transcripts are turned off. This is deliberately strict: the fetch costs us roughly a cent whether or not it yields text, and the buyer should not carry that.
