Integration

How to run it

The same lookup works from the app, the API, or as a tool an agent can call mid-task.

This endpoint is synchronous: the call blocks until the lookup completes and returns the records directly. If a lookup hits its time budget before finishing, the response comes back with partial: true and whatever it collected so far — re-run with smaller limits for a complete result. url is required. Optional: max_comments (1-1,000, default 20), sort_by (TOP_COMMENTS; leave it out for newest first), newer_than (a date or a period like 30 days — returns newest first).

curl -X POST https://api.neuralverge.ai/functions/v1/run-youtube-comments \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "url": "https://www.youtube.com/watch?v=RIRyuq-AKOU", "max_comments": 100, "sort_by": "TOP_COMMENTS" }'

Handling

This source returns publicly posted comments, which are written by private individuals.

Every record is stamped with the video it was read from and a session id you can trace.

What it will not do
  • —Publish times are relative text ("6 months ago"), not exact timestamps.
  • —Videos with comments turned off return nothing — and nothing is billed.
  • —Authors are handles only; no profile details come back.
FAQ

Questions, answered

Yes — every Data Source endpoint, including this one, is synchronous: the lookup runs inside the request and the result comes back in the same response, no polling. If a lookup hits its time budget before finishing, the response comes back with partial: true and whatever records it collected so far — re-run with smaller limits to get a complete result instead of a partial one.
