# HeyReagent, free: LinkedIn post comment API

> List the comments on one post, or the replies to one comment.

HeyReagent's Free plan for the LinkedIn post comment API costs $0.00 per 1,000 comments. We check each provider's docs for 2 fields. HeyReagent's docs list both: Comment and Commenter.
HeyReagent limits how many pages you get but gives no number.
We haven't run HeyReagent through [our LinkedIn post comment API benchmark](https://datacircle.dev/best-linkedin-post-comment-api.txt) yet.
This plan is free. We rank 148 plans for LinkedIn post comment APIs by price. Half the plans cost $0.49 or less per 1,000 comments. [See the best free LinkedIn post comment API plan.](https://datacircle.dev/best-linkedin-post-comment-api.txt)
