Reddit is a social news platform with user-driven communities (subreddits), offering content sharing, discussions, and viral marketing opportunities for brands On Nagent, Reddit is exposed as a fully-configurable social media accounts integration that any agent can call — 23 actions, and OAuth authentication. No code is required to wire Reddit into your workflow — connect it once via the External Integrations panel and reuse it across every agent you build.
Agent builders use Reddit to automate the kinds of tasks social media accounts teams previously handled manually. Concrete examples — each one is a single agent step in Nagent — include:
Every action and trigger is paired with a structured input/output schema (visible in the sections below), so when you wire Reddit into Helix — our agentic agent builder — the editor knows exactly what each step expects and produces. Configure once, deploy anywhere across your Nagent agents.
Every operation an agent can call against Reddit, with input parameters and output schema. Drop these into any step of an agent built in Helix.
REDDIT_CREATE_REDDIT_POSTCreates a new text or link post on a specified, existing Reddit subreddit, optionally applying a flair. Immediately publishes publicly visible content — confirm subreddit, title, and body with the user before executing. Posts may be silently removed post-submission by automoderator or subreddit rules (errors: SUBMIT_VALIDATION_BODY_BLACKLISTED_STRING, POST_GUIDANCE_VALIDATION_FAILED); verify visibility via the returned permalink. Rapid consecutive calls trigger RATELIMIT errors with cooldown hints.
Input parameters
The URL for a 'link' post. Required if `kind` is 'link'.
The type of the post. Use 'self' for a text-based post (when providing 'text') or 'link' for a post that links to an external URL (when providing 'url'). If omitted, it is automatically inferred: 'self' when 'text' is provided, 'link' when 'url' is provided.
The markdown-formatted text content for a 'self' post. Required if `kind` is 'self'. Body must not exceed ~40,000 characters.
The title of the post. Must be 300 characters or less.
ID of the post flair template (UUID format). Must be a valid flair template ID that exists for this specific subreddit. To get valid flair IDs, first use LIST_SUBREDDIT_POST_FLAIRS action for the target subreddit. Do not pass generic strings like 'general' or 'news' - these are not universal flair IDs. Some subreddits enforce mandatory flair; omitting or providing an invalid ID returns SUBMIT_VALIDATION_FLAIR_REQUIRED.
The name of the subreddit (without the 'r/' prefix) where the post will be submitted.

REDDIT_POST_REDDIT_COMMENTPosts a comment on Reddit, replying to an existing submission (post) or another comment. Fails if the target thread is locked, archived, or restricted — verify thread state beforehand. Rapid successive calls trigger Reddit RATELIMIT errors with explicit cooldown hints (e.g., 'take a break for 9 minutes'); honor the specified wait before retrying. A successful API response does not guarantee public visibility — automod or spam filters may silently remove the comment. Publishes immediately and publicly; confirm target and text before executing.
Input parameters
REQUIRED. The raw Markdown text of the comment to be submitted. This field must be provided and cannot be empty.
REQUIRED. The ID of the parent post (link) or comment, prefixed with 't3_' for a post (e.g., 't3_10omtdx') or 't1_' for a comment (e.g., 't1_h2g9w8l'). This field must be provided.

REDDIT_RETRIEVE_POST_COMMENTSRetrieves all comments for a Reddit post given its base-36 article ID. Response is a two-element listings array: post metadata in `listings\[0\]`; comments in `listings\[1\].data.children` with text at each `\[\].data.body` and nested replies under each comment's `replies` field. Replies require recursive traversal to capture full discussion. Large, locked, or archived threads may return truncated trees or `more` placeholders rather than full results. Filter out comments where `body` is `\[deleted\]` or `\[removed\]`; use `parent_id` to reconstruct conversation flow. No time-filter parameter — compare `created_utc` against a UTC cutoff to filter by date.
Input parameters
Base-36 ID of the Reddit post (e.g., 'q5u7q5'), typically found in the post's URL and not including the 't3_' prefix.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
REDDIT_RETRIEVE_REDDIT_POSTRetrieves posts from a specified, publicly accessible subreddit. Responses nest post data under `data.children\[\].data`; inspect the structure before parsing. Pagination uses a `data.after` cursor; deduplicate across pages by post `id`. No built-in date filtering; compare `created_utc` (Unix seconds, UTC) client-side. Rate limit: ~1–2 requests/second; back off on HTTP 429.
Input parameters
Sort order for posts. Options: 'hot' (default, most active posts), 'new' (newest first), 'top' (highest scoring), 'rising' (trending posts), 'controversial' (most controversial).
The name of the subreddit from which to retrieve posts (e.g., 'popular', 'pics'). Do not include 'r/'. Subreddit names must be 3-21 characters and can only contain letters, numbers, and underscores.
The maximum number of posts to return. Default is 5. Set to 0 to retrieve the maximum allowed by the Reddit API (100 posts). Valid range: 0-100.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
REDDIT_RETRIEVE_SPECIFIC_COMMENTRetrieves detailed information for a single Reddit comment or post using its fullname. Returns only the specified item, not surrounding thread context; use REDDIT_RETRIEVE_POST_COMMENTS for full discussion retrieval. Deleted, removed, or quarantined items may return empty or partial payloads.
Input parameters
Reddit fullname identifier. Format: type prefix (t1_ for comments, t3_ for posts) followed by a base36 ID. Examples: 't1_abc123', 't3_1abc2de'. Note: Share URL tokens from reddit.com/r/.../s/... links are NOT valid fullnames and cannot be used directly. Note: REDDIT_RETRIEVE_POST_COMMENTS expects the bare base-36 ID without the t3_ prefix, unlike this tool.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
REDDIT_SEARCH_ACROSS_SUBREDDITSSearches Reddit for posts/comments using a query. Results nested under `data.children\[i\].data` (kind `t3` for posts); a `posts` array may also appear — inspect actual response path. No native time-range filter; compare `created_utc` (Unix epoch, UTC) client-side for recency filtering. Empty `children` is a valid no-results outcome. Key post fields: `score`, `num_comments`, `created_utc`, `permalink`. Rate limit: ~1–2 requests/sec; HTTP 429 indicates throttling.
Input parameters
The criterion for sorting search results. 'relevance' (default) sorts by relevance to the query. 'hot' sorts by trending posts with recent upvotes and activity. 'new' sorts by newest first. 'top' sorts by highest score (typically all-time). 'comments' sorts by the number of comments.
Pagination cursor to fetch the next page of results. Use the `after` value from the previous response to get subsequent results.
The maximum number of search results to return. Default is 5. Maximum allowed value is 100. Paginate beyond the first page using the `after` cursor from `data.after` in the response; deduplicate results across pages by post `id`.
Pagination cursor to fetch the previous page of results. Use the `before` value from the previous response to get preceding results.
If True (default), confines the search to posts and comments within subreddits. If False, the search scope is broader and may include matching subreddit names or other Reddit entities.
The search query string. Supports Reddit search operators: 'title:', 'author:', 'subreddit:', 'url:', 'site:', 'flair:', 'self:yes/no', 'nsfw:yes/no', and boolean operators (AND, OR, NOT). Raw URLs (starting with http:// or https://) are not allowed - use the 'url:' or 'site:' operators instead (e.g., 'url:example.com' to find posts linking to that domain).

No publicly available marketplace agent is found using this tool yet. There are 90 agents privately built on Nagent that already use Reddit.
Build on Nagent
Connect Reddit to any Nagent agent in minutes — no API key management, no boilerplate. Just configure and deploy.
The five questions agent builders ask before adopting a new integration.
Open the External Integrations panel inside Nagent (app.nagent.ai/externalIntegration), find Reddit, and click "Connect Now." You'll authenticate with OAuth — Nagent handles credential storage and refresh automatically. Once connected, Reddit is available to any agent in your workspace.
No. Nagent provides no-code integration for every tool. Once Reddit is connected, you configure its 23 actions directly in the agent builder UI — no API calls, no boilerplate, no schema management.
Helix — Nagent's agentic agent builder — lets you drop Reddit steps into any workflow visually. Pick an action (e.g., one of those listed above), fill in the inputs (Helix knows the required vs. optional schema for each parameter), and connect it to upstream/downstream steps. Triggers run as the entry point of an agent, so when a Reddit event fires, the agent kicks off automatically.
Every Reddit action and trigger ships with a fully-typed schema — input parameters with name, type, required flag, and description, plus the output payload shape. The schemas are documented in the sections above. Helix uses these schemas to validate your configuration at build time and to type-check the data flowing between steps.
Yes. While Reddit ships with 23 pre-built social media accounts actions, you can layer custom logic around them inside Helix — pre/post-processing steps, conditional branches, retries, or stitching Reddit together with other connected tools. For deeper customization, talk to our team about Nagent's Agentic AI Lab — forward-deployed engineers who build Reddit-based workflows tailored to your business.
