Reddit Toolkit

The Reddit toolkit integrates Reddit's platform into Arcade, enabling LLMs to read and interact with Reddit content on behalf of authenticated users.

Identity & account: Retrieve the authenticated user's username and their own post history.
Subreddit discovery & moderation info: Check subreddit existence and access status, fetch subreddit rules, and list posts by listing type (hot, new, top, controversial) with time-range filtering.
Post retrieval: Fetch the content of a single post or multiple posts in one request; prefer the batch tool when retrieving more than one post.
Commenting & engagement: Read top-level comments on a post, reply to existing comments, and comment on posts.
Content creation: Submit new text-based posts to any accessible subreddit.

This toolkit uses OAuth 2.0 via Reddit as the identity provider. Arcade handles the OAuth flow automatically.

See the Reddit auth provider docs for setup and configuration details.
