Reddit User Activity API - Public Posts & Comments

Request the documented public activity listing for a bare username. filter selects comments or posts, sortType selects new, hot, or top, and cursor is an optional continuation value. The configured defaults are filter=comments and sortType=new. This endpoint has not been live-validated; its filtering, sorting, pagination, and current availability need validation before production use. The supplied documentation's comment sample has a body array with id, name, author, body, body_html, created_utc, subreddit, parent_id, link_id, link_title, link_permalink, permalink, and score. That sample describes comment records, not a verified schema for every mode. Do not assume post rows use the same text field or that every documented option returns the expected entity type. Follow only actual returned continuation values and treat the result as a bounded public activity sample, not a complete account archive or access to private activity.

API Features

Named-account activity scope Select a public username for the documented activity workflow rather than requesting an entire community's feed.

Posts or comments selector Choose the endpoint's documented posts or comments mode, validating actual row types before using either in an application.

Documented author-activity ordering Configure new, hot, or top through sortType; these modes and their returned ordering have not been live-confirmed.

Comment-sample linkage fields The documentation sample includes comment IDs, parent IDs, source-post links, text, and timestamps for traceable activity records.

Use Cases

After validating the activity filters, build a public author-activity panel for an explicitly selected account with links to its original discussions.
Assemble a bounded editorial timeline of public statements from an organization representative or project maintainer.
For a consent-based study, compare topics in returned public posts and comments without inferring an account's private behavior.
Test an ingestion pipeline against the documented comment row fields before enabling live collection or relying on post-mode schema assumptions.

Frequently asked questions

Was public user activity checked live?

No. This endpoint is included from its documentation and supplied sample, not a successful live request. Validate filtering, sorting, row shapes, cursors, and availability before building a production workflow around it.

Which activity filters and sort values should I start with?

The endpoint description documents posts and comments, ordered by new, hot, or top. The provided defaults are comments and new. Other entity filters mentioned in generic parameter wording are not offered here because they are not established account-activity modes.

Can I treat the returned activity as a complete account history?

No. Treat it as a bounded sample of available public activity. The documentation's comment sample uses body for text and includes post references, but post-mode fields and cursor behavior were not live-verified. Neither private activity nor complete historical coverage is promised.
