## Tool details

**About this tool**

Reddit: fetch post comments (app) Retrieve one bounded result or page. Pagination is explicit; each follow-up page is another call. The catalog price is the maximum per request. Quotes use the selected limits. Completed requests cost their quote, including valid empty pages and no-match answers. Failed requests are uncharged. Read public social data without a connected social account. Results include reviewed business data and available pagination. The worked example shows selected fields from a recorded response, with at most one selected item from each list.

**Inputs and outputs**

### Input

`after` string · optional

Pagination parameter for fetching next page

minLength: 1 · maxLength: 500

`post_id` string · required

Reddit post FULLNAME — the t3_ prefix is required. Build it from the URL: reddit.com/r/.../comments/1v7z1m7/ → t3_1v7z1m7. A bare id answers HTTP 200 with data.postInfoById null and STILL BILLS (see miss).

minLength: 1 · maxLength: 30

`sort_type` string · optional

Sort method: CONFIDENCE, NEW, TOP, HOT, CONTROVERSIAL, OLD, RANDOM

minLength: 1 · maxLength: 500

### Output

`data` object

Returned data value.
