YouTube Replies API

Comment replies on a video. Use `limit` to say how many you want.

YouTube API pricing — $0.50 per 1,000 results

POST /api/public/v1/scrape/youtube/replies

Returns comment_reply_api

Parameters#

video_id string required

The id from watch?v=<id> in the video URL.

Example: dQw4w9WgXcQ

limit integer optional

How many results you want. The run is sized from it, and you are billed for exactly that many.

Results#

GET /runs/:id/results answers with this once the run has finished — one reply per row.

Every row also carries raw_json — the platform's own object for that row, exactly as it arrived, with nothing removed. It is left out of the example for length.

This endpoint errs towards returning more rather than less, so expect a few extra rows alongside what you asked for. Everything still comes back typed and parsed the same way.
